- After a few weeks using the Aiyima T9, I knew it would be tough to make a short video due it all of it's strange quirks. If you can hang in there, I show all of the features, what I find annoying and compare the T9 to my Cambridge AXA25 amp.
I recently purchased the T9 Pro and did a comparison video with the OG model here: • Did they really fix EV...
Purchase here: amzn.to/3zPOKwW
Also, apologies in advance for calling the T9's outputs when I meant obviously meant inputs, lol.

Aiyima T9 Review - เพลง
I recently purchased the T9 PRO model and compared it with this OG model to see if they fixed everything. Check out the link to that video in the description above!
I bought my T9 from Randy's review and I've been really impressed. I used it to drive my Magnepan MMG's, which are demanding 4 Ohm speakers and it drove them plenty loud and clear. It doesn't have the rich lusciousness of my McIntosh MA6900 integrated; but, at 3% of the price of my McIntosh, it's a respectable little Class D integrated amp
Awesome. I’m enjoying mine as well! Thank you for watching the nice comment.
Just the review I was looking for. Many thanks!!
Thank you! I was hoping to make a shorter video but it’s such an odd unit that I went in deep to try and include everything lol.
Great job :) Any way I agree with you on getting a Cambridge Audio which, by the way, is amazing!
Thank you for the info!
And I love the Minor Threat painting in the background.
Thank you for watching. I bought the artwork from Nathan McKee!
You are great at explaining things compared to other channels.
Thank you! That really means a lot as a new channel.
Good video. I like the fact this product exists
Thank you for watching!
Bought mine 5 month ago and I was also impressed! Well, and now I put a pair of GE Jan 5654W valves 🤩 Now it's more precisely at the hights, more definition, airly. Worthing also each centavo! Next step will be changing the capacitor...
Awesome. Thanks for watching!
I need to change up my old amp and this definitely seems the way forward thank you
Check out the update T9 pro model as well!
Thanks for the review. What speakers did you use for the comparison? I happen to have CA axa35 series plus the CD player. Very surprise if the sound is the same. If the tubes are just buffer, did you test if the T9 can run without the tubes?
I bought the T9 3 months ago, I have a pair of Chinese-made Q6 Toulihao single-source speakers. Together they sound really great. The Q6 are 8 ohms and 93 dB sensitivity. I am amazed at what sound comes out of this set-up. The clicking does not disturb me at all. The DAC inside the T9 is also decent. BTW I paid US$ 72 for my T9 and $350 for the Q6. They worth every penny I paid.
Awesome!
Hello, I'm also one of those who bought one of these amps based on Randy's review, then saw the "caveat emptor" review that Sean posted before my purchase arrived. Naturally, I was pretty anxious about what I'd be getting. I've had mine for a while now, and honestly, I totally love it! I did not have the severe clicking issue that some have reported, but did notice that the amp does have some kind of a "sleep" mode if input goes away on some modes. I tried all inputs except coax, as I have no source for that mode, and the amp sounds great with all of them. I use it to drive some little Polk T15 speakers, and they sound very good to my ear. As far as the remote issue - what I believe is happening is that the IR coding that Aiyima uses obviously has some similarities to codes of other IR systems. I have had the issue you describe with other IR remotes for my TV and some other audio equipment. It's not particular to Aiyima, unfortunately, and to resolve it would require Aiyima having a database of every other IR remote system's coding, and finding codes that were unique to them. I'm pretty sure that's not going to happen any time soon. My BT seems to work just fine, it only connects to sources it has already paired with, as far as I can tell.
All in all, I am very pleased with my purchase, and hope that Aiyima fixes what appear to be quality control problems. One thing that does come to mind is that I recall reading on a review somewhere; a user had asked Aiyima about the clicking, and their reply was that it was an intentional design they added, as the TI amp chip doesn't do that natively. Perhaps some enterprising engineer will figure out what activates that circuit and come up with a simple mod to eliminate it???
Yes to everything you mention. Very well put!
I literally had the same scenario - saw Randys video went out and got (the Douke Audio St-01 in my case - same thing) Then saw the OTHER video that Sean Posted - and was anxious as well! In fact I feel like I have been looking for things wrong this amp - but I cant find any. I get the clicking every once in a while if Im not using the amp and left it on - it actually reminds me to turn it off! Other then that its been great. I plan on making a full review video about it.
@@PiecesofVinyl awesome news. Also just subscribed and looking forward to your review!
@@PiecesofVinyl What is interesting is that I've noticed that when I have the amp plugged into my laptop, using it as a USB sound card, when I'm working in Audacity doing sound editing, there is sometimes a small delay until the amp kicks on when I start playing a track, but if I'm in Amazon music, as soon as I select a track to play, I hear the amp kick on. Apparently some function tells the amp that sound is coming! The Audacity issue is not really a problem for me, but IO can see how some would see it as make or break issue. I've been using mine pretty regularly for a while now, and it is just a great-sounding little amp.
I just ordered one, I’m going to use it for my portable backyard system with Sony sscs5 speakers. Hoping for an early spring
That will be a perfect use! Thanks for watching!
It's so fun that the remote control can cross-transmit with the TV signal. I think you should install a radio barrier between the two.:)
I just bought the normal T9 from Amazon a few days ago, and im happy to say they have the option to disable the "auto mute" function with the remote, which eliminates that weird clicking sound
Great to know. Thanks for sharing!
Normal T9 not the pro? Upgraded version? How to disable the auto mute? What box of your T9?
@@ArczAngel I have the normal, not the pro,
If you read the manual of their latest shipments (I got mine from Amazon a few days ago), you'll see that the "M1" button on the remote disables the auto mute function, so when the music or audio gets to a period of silence longer than 10 seconds, it won't click anymore or cut out the audio
You still hear the click when you switch inputs, but not during actual listening, so you won't hear that intermittent random clicking when watching a movie or when it's hooked up to your computer.
And yes, after the amp is powered off and powered back on again, it saves the setting and keeps the "auto mute" feature disabled
Also for those of you who don't own a T9 and have not heard this clicking sound in person, I should note that the clicking sound is just a mechanical relay sound coming from the T9 box itself. The click sound does not get played through the speakers
¡Aloha from Spain! Thank you for the honest review! Here in my country the T9 is at 103€ and the D03 at 123€. Which one would you recommend for a desktop/TV soundbar replacement? I'd use it with a pair of Jamo S803 I recently bought.
Is there anything better for 150/200? Thank you!
Thanks for watching! Hmm, I’ve only owned the T9 so I can’t make an honest comparison to the D03 at this time.
Nice video mate thanks. Is it way better than he A07? Nice seeing Randy get such recognition
Do you mean the A07? I only have the A07 Max and working on video comparing it to Fosi V3, but on the T9 or T9 Pro. I like the T9 models offer more connectivity options which you would find more valuable than a difference in sound which is often very minimal at this price point (to my ears at least).
@ForeverAnalog yes sorry, typo. Ok I see, will be looking forward to the video, mate. I feel the same way wrt connectivity options, I had the A07, I liked but not loved it. Reliable and never had issues. I understand what u say about the sound for price, also. But if u were to decide solely on sound, I guess the T9? I didn't know ow there was an A07 Max lol
How would you hook up a Schiit mini equalizer to the T9 Pro?
I enjoyed your review! Thanks. My Aiyima T9 has been my daily computer amp for 6 months now with no problems at all. I swapped in GE tubes right away, mainly just a habit from the Seventies when Telefunkens and Amperex made noticeable sonic improvements on my old modified Dynaco 70 and PAS3a preamp...back when Chinese everything was a no-no :/...but I'm presently really enjoying the sound from this amp. Very detailed and lifelike imo. :)
Thank you for watching. Yeah I think your set up is the optimal use for the T9. Great info on the tubes. Very informative, thank you!
I really love the Russian tubes too! but I have the Douk x1.
I finally bought this and a pair of Sony ss-cs5 about four months ago after 7 years of loving a $40 nobsound with 20 year old Sony three-ways... and I'm completely floored by how great music can sound at this price point.
Awesome! Enjoy and thank you for watching!
How can you tell what the volume level is with no markings on the volume dial??
I don't know about the Aiyima T9, but according to Douk Audio's eBay store, "doukmall", the company has fixed the issue for the Douk Audio ST-01 and the Douk Audio ST-01 Pro. "Add a M1 button on the remote control of ST-01 and ST-01 PRO, to turn on and off the function that it will auto enter mute mode when there is no signal input for 10s."
I can confirm this is true for the the Douk Audio ST-01 since I own one and it's one amazing-sounding amplifier! Douk Audio should be sending me a monthly check for this testimonial. 🤣
I will second your motion for a royalty check lol! Thanks for the update!
Hi. I buy elac debut 6.2 its good for that bars???
If you base your sound experience on a CD player. They are both using sonya cd dac system. Don't play it down on less you upgrade to a high end CD player. Tubes generally sound warmer.
Very useful video 👌👌💞💞
Thank you!
hi, great video. will the USB connection to this DAC from my I MAC play through my computer speakers the are connected to my computer on the headphone jack?
No. The USB connection is for power only, not an audio connection.
Is there a problem with t9? Is there a delay problem?
Did you compare both amps at high volume? I've got one of these and when I turn it up loud I don't hear any distortion or clipping.
I played it loud but not enough to distort or clip. No one in my house would enjoy that process lol.
MINE has never clicked. The sound quality is great. Apartment loud, not college party loud. I respectfully have no time to intellectualize about. Great choice of inputs for what it is. $129 on Amazon.
Awesome. Thank you for watching!
thanks for the review. insaneeeeeeeeeeeeee that this product exists. 3 well known youtubers say that a $150 amp with analog and digital sounds really good. insaneeeeeeeeeeee
Thanks for watching. I think those of us reviewing this are surprised at how well it sounds for just $150 lol. But I’ll most likely keep my regular gear in place for now.
@@ForeverAnalog Yeah, true that. My old Rotel integrated is acting up. Here in Canada the CA AXR85 is reduced to $729. So that is an option. But I was reading amazon reviews and there are people with really solid gear running cheap class D amps now, like the Aiyima A07. We will see.
Because all of those tubes are pentodes, i assume that's why, and they are preamp tubes, i have the 5654 from sylvania (USA) and 6ak5 from OTK-1 (Russia), and another pair of 6AK5 from CEI (Russia again), the 6J1 are chinese equivalent of these that i mentioned. i only can say that im curious because these vacumm tubes (6AK5 and 5654, and 6J1) are sorter in leght (they are actually smaller) than the 6K4. Take note that the Aiyima t9 pro has 6j1 from factory.
The edit was because I put the wrong number on the vacuum tube from Silvania.
Just found the channel and Sub'd, good video!
Thank you!
LIKE number 1 which is always fun. :)
review is missing details about the speakers used and ... what's in the amp?... what chip, etc.
For those who are curious, a few days ago Aiyima announced the updated T9 PRO. Here are the electronic differences in the new model:
TPA 3250 Power Amp Chip (unchanged)
100W x 2 (unchanged)
DC 18V to 32V (note says: Power will be more sufficient)
Tube is now a JAN5725
Display screen & VU Meter.
Display Spectrum
Bluetooth is now QCC3031, Bluetooth 5.0, Apt-X HD
Decoding Chip is now ES9018K2M
OP amp Chip is now DSP Sound Chip
MCU chip is now NJW1194
PC-USB is now SAS9123L (24bit/192Khz)
Inductance is now Phase Mode Choke (from Winding Inductance)
Single chip Microcomputer is now the AT32F421K8T7
and finally, they put some blingy gold rings around the meter and display.
So, the old one had only a VU Meter, the new one has two round displays, VU meter, and now a digital display.
Controls are now digital, so no mechanical Bass and Treble. The specs suggest not really an update, but an entirely new model. How does it sound? What about longevity? Clicking sounds?
All answers to be had!
Did you describe the sound?
Can you hook this up to your stereo receiver and use Bluetooth play music from my phone
No this can only be used to power speakers and not as a preamp. Check out the Wiim mini pro if you need to stream to your receiver.
BUYER BEWARE is valid! I got the unit from Amazon two weeks ago, and it regularly clicked. It also had an issue with the remote being unable to adjust the volume or select inputs. The unit sounds terrific but is useless with all of these defects. The SMSL DA9 and AO200 are more expensive but worth every penny more! The Cambridge Audio is a WAY more dependable option. I actually ended up just paying way more and went with the PS Audio Sprout.
The Sprout is awesome!
Hi. Did you pay $599-$699 for the Sprout. I saw a review where he said it was $599. But here in Canada, I saw the Sprout selling for $1299. i am confused.
Seems like no one can answer this question..can this amp be used with a dj dvs system which is vinyl controllers with laptop and analog mixer?
Depends on the outputs of the DVS as the T9 has RCA inputs and not XLR.
@@ForeverAnalog The mixer has RCA outputs. I'm hoping that I won't need a separate DAC for sound output. Great review. Somehow I trust your review more than cheapsoundguy
@@coldcrush1 also check out my T9 Pro review. It might be an even better option! Also, these are easy to return via Amazon if you order and it doesn’t work out. But I hooked up my Numark mixer to the OG T9 and used my 1200s to spin records fine at home. I don’t know that I would use this amp in a live setting but for home use it was fine!
Customers on Amazon have reported yet another quirk that is a total dealbreaker for me.
The tubes seem to interfere with DAB+ reception, making it impossible to receive any DAB station !
Interesting. Thank you for sharing!
@@ForeverAnalog You're welcome. Please note that I cannot confirm this quirk, but I was planning on buying the T9 specifically for a DAB receiver, and after reading the Amazon reviews I decided to skip the T9. Also, there are more components inside the T9 that can cause interference than just the tubes. It could even be related to the power brick.
in every review I have seen no one talks about the bluetooth and what it sounds like. I wonder if that means they never tested it, or it sounded the same as any other source.
Bluetooth sounds fine! I would suggest using Tidal or Quobuz over Spotify for best performance.
@@ForeverAnalog do you know what codecs it uses?
I just bought a A07 pro and upgraded to 48v 5a is it normal for amp to runs warm even when not using or volume is turned town. It doesn’t shut off or anything? And sounds fine no static or hissing. Should I go back to stock PSU?
Folks have left comments on my other class d videos advising against the upgraded power supply. Check out comments on my video on the a08 pro.
@@ForeverAnalog thank you
I use a T9 in combination with a pair of Fenton speakers I bought for 59 euro and a Vulkkano 8 inch active subwoofer for 109 euro.
Awesome! Thanks for watching!
I believe that Shawn's unit was going to sleep, shorting, thus causing it to recieve siginal and wake up, then going back to sleep.
Totally agree!
Hey just subbed got some wharfedale diamond bookshelf speakers and have a ao7 power amp knocking around going to use this for my son as has optical Bluetooth etc out of curiosity I see it has one set of rca could you run a power amp with this ?
Thanks! According to Aiyima, one could connect the T9 to a power amp via the 3.5 mm jack on the rear of the unit. I did not test this option out so can’t speak to how well it works.
That's great thank you very much would it use 3.5 jack to rca or 3.5 jack to 3.5
I believe it would go 3.5 from the T9 to RCA into the A07.
Great fantastic I will give it a try 😀
Hi buddy I contacted aiyima direct they say you can't run a power amp with the t9
I've had my T9 for about 2 weeks and I bought it for my small bedroom and it works fine for what it is. The only issue I have with it is the Bluetooth connectivity. I live in an apartment building and one day after work when I turned on the T9 and the integrated amp I am running the T9 through, I then reached for my phone to start my music player, but I heard music coming through my speakers and I hadn't turned the Bluetooth or the music player on. The T9 picked up a neighbor's BT signal and there is no way to select or prioritize which BT signal that the T9 connects to. It just grabs the first one it encounters. I wrote Aiyima to ask if they have a work around or if they have plans to have a passcode written into the software so only the holder of the code can connect and they said no to both questions.
I figured that those of us that could encounter this problem should make sure your device must be on with the BT signal already sending out first, then turn on the T9 and it should connect to you since the closer stronger signal will get connected. Seems to work so far doing it that way.
That’s wild about the Bluetooth. Thank you for sharing!
@@ForeverAnalog --- you know, it never crossed my mind that there wouldn't be a way to prioritize which BT signal the T9 receives.
I thought maybe there was a way but I wasn't figuring it out. That is when I wrote Aiyima and got that very surprising reply that there was no way to control the BT connection AND they thought my suggestion for a password or code was a good idea but they had no plans of any such changes for the future as of now.
I'm no electronics or computer guy, I'm just a 30 yr experience electrician but I would imagine it couldn't be much work to program a code into the device that only the owner would have and it has to match the devices for them to pair up. I guess that would raise the cost of the T9 and crush their profit margin. Hahahahaha
@@13_13k you are correct and what I wonder is if they just crank these out quickly and then see negative reviews and THEN fix it before sending out the next batch. So who knows, your issue just might get fixed in the future! I suppose in the end we can't ask too much from a $150 device, lol.
@@ForeverAnalog ---- I agree with all your points. It would be the logical way to get a cheap product on shelves and to deal with issues in the next production run. My unit is part of the new stock after they sold out on Amazon recently and the issues people were having prior to that time were the clicking noise and something I can't remember right now but I don't have any other problems so far.
It can't just be my T9 doing this, it has to be all of them, I would think every unit would do the same thing.
You could check it by having a phone with its music or a podcast playing with its BT on in another room close by and then turn on the T9 and another device's BT with music or whatever and it will pair with whichever signal it receives first and there is no way to change it. They all must do the same thing.
@@13_13k Would you please tell me if in the faceplate of your unit the model designation is: TUBE-T9 or just T9. I realised that are both of these out there and started to think if one or the other could be a newer version with the clicking issue fixed. Many thanks!
I have Audio Technica turn table with built in preamp. Can I use this tube amp to make the sound warm on my powered Edifier speakers?
No. This amp is for passive speakers, not powered speakers like the Edifiers. You might want to shop for a tube phono preamp instead to insert between the turntable and the powered speakers.
@@ForeverAnalog Thank you so much. One last question: will something like Fosi Audio Box X2 do the trick?
@@chandrakant1479 yep, that will work great! can't speak to how it sounds as I've never used it but Amazon has easy returns should it not sound like you hoped.
@@ForeverAnalog once again thank you so much for your time :)
@@chandrakant1479 any time! Enjoy the new gear!
Did anyone have a lot of sparks flying out when plugging in the power cable to their T9? I can't tell if that's normal or if I got a defective unit.
Yikes. No sparks here. Was yours powered on by chance? The speaker connections are crammed in there so if it was accidentally powered on I could see how crossing wires would be easy.
This happened to me too hopefully it didn’t damage it
Hello.
My question is; do the 'clicks' come from the amp itself, or from the speaker?
Just from the amp!
@@ForeverAnalog Thank you.
@@ForeverAnalog I have purchased a Aiyima T9 to power the audio side of my computer/gaming system. To reduce extraneous noise I keep the computer and associated fans in a different room. I pass all the required cables through a small hole in the wall to run the screen etc. in my actual leisure room. The T9 will live in the computer room so it is unlikely I will hear a relay click.
Therefore, knowing the 'click' is an amp side problem, my mood has improved.
My T9 arrives in three weeks.
Thank you again. Your video has been most helpful.
Thank you! Hope you enjoy the T9!
@@ForeverAnalog I've been using my T9 for a while now and these are my thoughts.
I like the T9. Plenty of power for my application and clear as a bell. I used the usb connection with no issues at all.
The 'click power saving' problem is interesting. I am unable to hear the 'click' as the amplifier is in a different room, but I find if I have had no sound for a while (more then 10 seconds), I lose the first 1/2 second of new sound. Mostly unnoticeable if it's action or music, but a voice may have the first word cut in half. To me not too much of an issue. A good chance I wouldn't have noticed if I was not forewarned. If the power saving started after 30 seconds, then even less of a problem.
A benefit of the power saving is the silence issuing from the speakers when the power saving clicks in. A funny thing, and small, but I think it's awesome. No idle hum, not that there was much in the first place.
I would purchase the T9 again.
15:16 No, that's just expectation bias based on equipment cost. Just because it's cheap doesn't mean to say it's rubbish. There's a lot of very expensive hyped up rubbish out there, together with a great deal of denial by those who've parted with good money for it. The sooner audiophiles lose the "it's only good if it's expensive" snobby attitude, the sooner we get more good gear at sensible prices. This is also why pro audio equipment by the likes of Benchmark and RME is priced sensibly: audio engineers are not audiofools.
16:20 The pre-amp section is active and buffered by the tubes, so they are part of the pre-amplification. The Class D part of the amp is its power amplification section and if you wish to use the T9 as a pre-amp only, you use the line in (not any of the digital inputs) and line out.
16:35 And who would spend that amount of money, I wonder, on an amplifier who's design had been matured decades earlier (no R & D) and who's cost (including components and assembly) would probably sum to £200?
I find that what "makes" the T9 is its pre-amp section; the DAC section's nothing to write about and I'm not bothered about the power amp section. Feeding the T9 with output from an Arcam rDAC into and into an Arcam Alpha 9P power amp produces astonishingly good results, better than using an Arcam Alpha 7R as pre-amp to the Arcam 9P.
o unico problema do teste é que a fonte sonora nao foi a mesma e segundo meus conhecimentos os CD player Cambridge é superior ao modelo sony usado no teste
can you use this as a stand alone DAC?
I don't think so as it's meant to be used as an integrated amp to power speakers.
Thank you for the reply!
How hot is this amp supposed to get? Got mine recently and it is runs very hot. This is my first amp so I know nothing about them.
Hmmm. Mine has yet to ever run hot so that makes me worry a bit.
Has anyone tried the new replacement version, the T9 Pro yet?
I have not! Is there a big difference in the newer model?
@@ForeverAnalog according to the, yes. Lots of changes and improvements. I've requested to review it, but they are out of stock.
Hope you get your hands on one soon!
Subbed,,,,,
I guess the power symbol below the on button is quite small, but it is inverted compared to the other writing..... I noticed it pretty well straight away to be honest lol. :)
Thanks for the information. Looks like these amps are a little hit and miss as to the quality you get. The GE 5654w Tubes are pretty good as are NOS 6AK5's. There are considerable substitutions with tubes available. Just do research as some tubes are expensive. As far as warranty, Amazon have to abide by the legal requirements in the consumer laws for your country, so if you buy from Amazon or similar place you will have at minimum your legally binding warranty.
Thank you for watching!
My questions - what is the purpose of the tubes in a class-D amp, and if this takes digital in, then it contains a DAC - can we get that briefly reviewed? People sometimes treat 'digital in' as just another input, when it really means you're buying a DAC along with everything else. Let's hear about the DAC chipset and performance, which can be a big deal depending on how you use the unit. Otherwise, loved the review, thx.
The tube is acting as a buffer. Lots of fun arguments in the world as to whether or not buffers really sound like a proper tube set up. I haven’t used this amp much since reviewing but I recall it didn’t sound anything like my Primaluna tube preamp which is not surprising.
Massive thanks for pointing out the non compatibility with a turntable without a phono saved me going down a rabbit hole only to find out this isn't for me lol
It’s an important feature missing that people often overlook! I’ve noticed most of these small class D amps often do not come with phono inputs.
@@ForeverAnalog one ive found and im looking at now is a AIYIMA T5 6K4 don't suppose you have any experience with it?
I don’t but I looked online and just wanted to point out that it’s a preamp only and doesn’t have a phono input either.
@@ForeverAnalog the one I found on Amazon says it does, two secs!

@@ForeverAnalog sorry my English is not good.
Thank you I’ll probably save up and get a more expensive option….maybe Akitika….on another note nb I must pick up some mastodon.
I would love to build an Akitika amp!
🤩clicking stop solution-🤩
To all those who bought this nifty little amp please press m1 on your remote to stop clicking in the amp worked on my unit no click From then 🥳🥳🥳
Great tip thank you
I've bought tons of cheap Chinese stuff. I've almost never had any problems. And when I have had any problems, the item was so inexpensive I really didn't care.
Yeah I’ll probably buy more just for fun lol
The T9 Aiyima sounds better😇
Uunfortunatly, just as the t6 pro which i have the dac is poor and you cannot bypass it as there is no spdif/optical out on these devices. Switching between my Cambridge Audio CXR120 Dac and the t6 pro dac revieled to me the Aiyama's dac is sinoly ni match. On all fronts the Cambridge Audio sounds better, way better. So, these rube amps with mediocre dacs and no spdif out, are cute toys but not for your hone hifi gear Buyers beware!!
The Douk Audio ST-01 is actually a bit cheaper. And exactly the same. 😀
Good to know! Thank you for sharing.
I own one of these for use with my PC and while the 'clicks' don't annoy me, the 10 second auto standby does as it takes the T9 a few seconds to restart playback. I am always missing the first few seconds of recordings/conversations when it resumes playback. This can be particularly annoying when using video messaging programs like Skype. Also, the 100W into 4ohms and 50W into 8ohms may not be accurate as Aiyima often rate the power output at 10% distortion.
It’s such a strange little amp. Thank you for further pointing these issues out!
@@ForeverAnalog I also have an Aiyima A08. This is a pure Class D amp with DAC which I feel sounds better than the T9. However my example has two issues. The first is there is a bit of noise on start up that disappears after around 20 seconds to a persistent 'tick' from the speakers. I have managed to reduce this noise by routing the internal mains wires a bit better and placing the op-amps on chip blocks. I am currently waiting on some replacement op-amps in the hope it solves the issue completely. The other problem is with USB input which has the occasional stutter and cuts out momentarily. I am not sure if this is a buffering or driver problem but there are no software updates to correct it.
If I'm playing a cd or feeding a Turntable through this thing am I going to experience this delay?
@@crazyprayingmantis5596 From memory, this delay is only on the USB input. Pretty sure it doesn't occur with the RCA inputs. Haven't tested it with the optical or digital coaxial inputs.
i ask randy about it but he dosent reply to his viewers lol so i was just about to buy a vintage reciever pioneer sx 680 30 watts and use it to run my internet radio and play mp3s and youtube maybe a cd sometimes but then i saw this and figured it out .the new version has corrected the bugs .i see most of these that function well .the vintage reciever is gonna need repaired sooner or later unless you triple pay and get ripped of from one of these audiophile repair men that think they have to support a wife and 3 kids on the repairs but i still see many old timer tv repairmen that will repair them for half the price of some of these rip off guys on here and ebay so maybe im better off with this t9 pro .maybe the pioneer would sound better than the class d or mor vintage which i want so not made up my mind yet but i like the look of this t9 pro and littlebear looks a little vintage very cool but i dont buy this shit just for looks lol which one will sound better im playing mostly digital music so maybe it dosent matter also i see pure tube amps 6.8 watts for about 350.00 that is pure tube so i think maybe you can get pure tube from douk or the uk nobsound 6p1 do you know about this amp ???i think its pure tube maybe a good deal not sure anyway thanks for your video
I have a tube amp but not from Douk
@@ForeverAnalog do you know of any chaeper ones 300-400 range that are full tube thanks
If you look at my recent videos, I reviewed one but it has to be ordered from Ali Express, I think it was around $300. Unfortunately, I haven't heard the other tube amps to be able to say one is better than the other. I hope to stumble on one soon!
The click indicates that you have taken the power off the main drive of the amplifier the next click tells you that the amplifier is ready to accept an audio signal. These three amplifiers are all.from the same factory in China. Aiyilma T9,Fosi T 20 and probably a few others. The power supplies are close in voltage. As to details. No they aren't that similar. Thee Aiyilma T9 has a warmer sound and is very detailed in the mids.And as to your comparing them with other amps. Remember the speakers are never the total reality.
Thanks for watching!
Love my Cambridge Azur 851A Amp...
Wonderful. Thank you for watching!
if click drives u crazy u need get help, hahaha
dei deslike depois que vi nao ter feito o teste de audio para o telespectador ouvir com fone
Why are you rationalising a reason to buy or not as if you don’t want it sold necessarily sold don’t say anything, we know you are American and don’t want to be pushing the enemy’s product!
