I'm just here to say that I appreciate Aiyima equipment. It suits my budget. I have an Aiyima A5 Pro DAC connected to one of my Rasperry Pi Volumio nodes. It works great and it is super simple
I am old man so I am often wrong on the internet! I would call this an intergrated amplifier! Why? Because that is what you call an amplifier when it intergrates other functionality like a preamp or DAC. If it had a tuner in it and amplifier it would be a Intergrated amp with tuner or tuner/Intergrated amp etc......When I was a child the first "intergrated amplifiers" combined pre-amplifier with the amplifier. I have to say that made far more sense than the Monster Recievers that came before that had 250wpc housed in an AM/FM Tuner that was often huge! To my way of thinking the Pre-Amplifer function is huge since a preamp can cost you a small fortune so having that functionality in this black box with amp is the huge the DAC is icing on the cake if you need a DAC. It appears that is has tone controls. If it also has built in eq no matter the type it is quickly aproaching an all in one solution just needing a tuner. Maybe add in HDMI ARC functionality that works every time and is idiot proof and again your approaching what could be an all in one box for a younger person with a small apartment a phone and some speakers.
Hi! Thanks so much. In future reviews, if you have a moment to give info on what formats can be sent into the Coax input it would be useful to know. There are several options these days that come via that cable so please expand (I like to be able to send AES without using an additional stage for example. Or other digital formats that may need selection in the menu etc). Cheers.
I've used Aiyima dac/amps in the past and have been pleased with their sound and features. I was running an Aiyima D05 up until recently but upgraded to something better. The A80 has very similar specs and inputs/outputs to the D05 but has a newer screen (the A05 also has a proper rca sub out). I'm sure the A80 is a solid product.
Please consult the TI TPA3255 datasheet regarding power output . A 48 V 10 A power supply is required to produce 300 Wpc. Ideally, the chip should have 51-54 V according to TI. A trimmable fan-cooled power supply is ideal. These units are often bundled with lesser power supplies.
Enjoy your channel, and your British humor is growing on me...I would like to point out, however, that you should be careful to account for inefficiency when projecting the potential max power output of the amp by observing the max wattage consumption of the amp's power supply. I realize it's a class D and therefore pretty efficient, but would guess that not all the 240 watts from the power supply are getting to the speakers as true effective power, due to losses. You pointed out that it's rated at 300 watts per channel at 4 Ohms, so a good guess might be 150 watts per channel at 8 Ohms...but then again... Also, with most of these little Chinese class D amps, you can replace the stock power supply with one having higher voltage and or amperage and develop even more output power to the speakers, something possible with the outboard power supply and not so easily done if it was internal...Of course, one would need to check the maximum voltage in, usually printed right next to where the power supply cord goes into the amp! Enjoy this channel, please carry on!
As soon as you revealed the power output of the external brick, I wondered if it was charging lithium cells internally storing up power for those 300 watt bursts. No big capacitors in that lil' box.
I have never used optic connection. It seems too Jetsons for my vintage tastes. I am still getting used to the idea of stereo, after all. However that said -- from the purchase a cheap soundbar for use under my desktop monitor when I don't feel like firing up the real equipment, I acquired my first optic cable. I had it coiled up for storage in my desk drawer, or so I thought. It somehow got caught in the drawer works and snapped in half. Not even the cheapest speaker wire from a 1970's combo stereo would have done that. For me, it is copper and gold all the way, in the A and D domains. Optics, schmoptics! Thanks for a nice review. PS I thought hey there's the headphone jack right there on the back with the hash marks around it.
Speaking of practicality-I got a Fosi ZD3 SPECIFICALLY because reviewers thought it was decent for its very cheap price *AND* it has HDMI (ARC) for my TV! (as well as blue tooth, both of which I have been using exclusively). This doesn’t have HDMI.
Aiyima products are win win i.e good products n cost friendly. I have two sets of power n mono aiyima amplifier. I put my yamaha n Sony entry level amp. into state of hibernation.. Tq Aiyima engineering engineering
The Yamaha NS-10s were ubiquitous in studios large and small in the 1980s and 1990s. They were so popular that as a teenager I spray painted the cones on my no-name speakers. Sad but true.
I'm a little disappointed you never open these things up. I'm not expecting you to do a breakdown of the electronics or explain the signal path but I would like to see the quality of the build.
Now don't go casting aspersionson on the wisdom of using optical inputs and outputs. Sure, the Toslink standard has been around for a while now, but for connection between a digital source and a DAC, the Toshiba link - with it's immunity to RFI, EMI and ground loop noise coupled with a high bandwidth, is the cable of choice.
Now, now specifications only demonstrate overall through put and don't affect the sound as much as the components used in a speakers crossover. I refer you to Danny Richie's channel and his showing 3 identical crossovers each produce the same frequency response in measurements yet with each unit the components increase in quality as subsequently costs, but that's not the reason for the demonstration, but how they change the sonic experience versus identically measuring the same with identical electrical impedances etc.
@@TriAmpMyFi Frankly, unless you have a need for super long cable runs, I think fibre optic USB cables are a little... overkill in domestic audio applications. I mean, it's not as if there is any audible difference at audio frequencies, and beside, have you compared the prices? However I can perhaps see the case for FO USB in studios and at live events.
@@Lif-999 Fiber Optic is cheap. About $100 for the convertor or PCie card & next to nothing for the LC to LC cable. It's not overkill because data streams are getting denser & denser every month. It's not just the distance for audiophiles, it's the DtoD optical bridge to reduce noise.
But those do allow for an upgrade path. Please see my other post for details. Also, it allows for heat dissipation to occur outside the amp enclosure. But yeah, they're ugly!
Really, oh dear?? Another cheap looking Chinese product from a make we haven't heard of. You don't judge Hi-Fi by its specifications. They tell you very little. You judge it by its sound - which you barely mention. But the quoted power output was quite funny at least.
@@AudioMasterclass. Tone & Timbre are within the audible frequency range of average old people so nutz to the Golden Ears theory. And giving weight to one manufacturer's specification whilst making excuses for their others' isn't objective. Acid Jazz. Funk & Brass🔈🔉🔊
What's missing is sub out with selectable crossover frequency (high pass speakers+low pass sub). Also, it's not completely acurate to say when there are digital inputs there's a dac inside. You have digital amplifiers now that have those inputs but no dac inside.
Well it depends on what model, though none of the B&W 801 was actually specified to go below 20hz, the series 1 with no port became one with a port to augment low frequency base with a claimed +-2db at 20hz if you used an equalizer, the later 801 matrix with a 15" driver was +-2db at 37hz. All three went low, but relied on room gain and often EQ to get clean defined low frequencies. The Series 1 and 2 cannot handle the modern bass of movies all that well due to just how much gain is added to LF movie content, the bigger 801D could handle power a bit better but was way down in output level at meaningful low frequencies. Great speakers, but not your subwoofer class, subwoofer class is in my opinion below 20hz with meaningfull output.
If you had your speakers for long enough (mine is more than 30 years) the compliance has increased significantly and therefore so does the LF response. I bet if you measured them now you would find that they will operate far below 20 Hz. Much better than their original specification. A loudspeaker is about the only mechanical thing that gets better with age and use.
@@AudioMasterclass I think the gentleman / lady is referring to the lack of tb in your music re the spectroscope rendering. It had lots of bs and a fair bit of md but not so much tb. You probably cooked that separate spectrograph.

What about the DAC section? What’s the tech even? ESS SABR? Or AKM dual “velvet sound” tech?
Does Aiyima make a class a/b amplifier?

You don't see white cones that often...they look nice..

What is better than 1 VU meter? 2 VU meters!
I totally agree, I have way more than enough power supplies!
I had a minor dyslexia attack, I read it as Yamaha. There goes objectivity. It looks fine, the electronic VU meters looks comatose.

Give an example.
If you needed a sub woofer with B&W 801 there is something very wrong with them (or your ears)
Looking at the specs I could have a sub going down further into LF. On the other hand, I’m OK as I am.
