I tested this amp and the most unique feature in this price bracket was omitted in this amp review. It has a highpass filter and allows a very simple 2.1 setup, where speakers are only responsible for mid and high tones, while the heavy lifting is done by an active sub (using app you can select crossover at 50, 100,150, 200, 250 ad 300 Hz), hence 30W at 8Ohm is not that bad at all, especially in case of near field or desktop setting or if you an hook up the sub.
Is there an option which allows use of the subwoofer output without any high-pass filter? My main speakers and subwoofer amp work best with the main speakers naturally rolling off and meeting the subwoofer's roll-off in the middle. They don't need high-pass filtering. The video says the amp uses a low-pass filter for the sub output - he doesn't mention a high-pass filter for the main speaker outputs in conjunction with this. Hence I'm still wondering, is there a high-pass filter for the main speakers, or a low-pass filter for the subwoofer output, or does it use both of these?
The standout feature of this amp is the programmable DSP. You can adjust the EQ, harmonic excitation and sound stage etc. with the ACP workbench tool. When configured correctly the amp can sound amazing. My Android TV connects to the USB C DAC input via the USB A port on the TV. This offers the best sound output from the MV silicon DAC chip in the B50 SE as the sample rate is 48 KHz on both ends. There ACP tool can be used to adjust the gain for the various inputs. In my experience, the order of sound quality from the B50 SE is DAC, followed by Bluetooth, Optical and then Analog. Analog input quality takes a hit as there is A to D followed by D to A. Separate DSP settings can be assigned to the 6 x IR remote buttons. You can learn loads by experimenting with the DSP in this AMP.
I like the foam packaging in these Chinese boxes. That's another incentive for buying these Amps. Foam always comes in handy for bodging solutions to niggling little problems on my guitar pedal board.
Why I would watch you "unbox" is a curious pursuit I can't control...or maybe its your wonderful soothing voice....it can't be humans watching another open a box....something is going on here I can't see......haa
I _still_ call my electromagnetic receiver and decoder unit a wireless. It has nice glowing valves in it, and transformer hum that brings back memories of happy childhood. The wartime civilian wireless is a grand piece of kit.
If you want to demonstrate some speakers/amplifier, i think a good way to do so is to speak near speaker position and record how you sound. We know human voice and we get a feel of surroundings then when we hear the speakers in the same position we can deduce how they actually sound.
@@charlesngugi777 Hate to burst yer bubble there but any conductive material can act as an inductor *if you make a coil from it* Binding posts are not coils The actual inductance of a barrel connector or binding post is so totally trivial (in picohenries) as to be considered zero.
@@Douglas_Blake_579 Its ok if you prefer that kind of connector in the signal path and you can't hear the difference. They are not that bad compared to the iron connectors.
All I can say is thank goodness my interest in HiFi 10 years ago,and not finding a decent tech near by me, lead me down the path of learning to build my own amplifiers,pre-amps and speakers and cables.😊
I love the review, the added graphics, the dulcet tones, the humour, etc. I just don’t know what I am supposed to do with something like this. I have a small integrated amp (NAD c328), new Apple TV 4K, TT, CD Carousel, and a smart 4K TV. Most of my tv and music listening is through 2 HomePods via either ATV4K and my amp is currently used just for my TT. Would this device give me something extra? I have watched NODEs, Wiims, reviews and I just don’t know if these devices would give me something that I haven’t got or experienced. Any advice appreciated.
I recognise the song in your test. This 'birdie' themed song was early Pink Floyd. I loved it. They didn't. They decided to go off in a completey different direction. I often wonder what happened to them.
itll get there eventually, prob sound hasnt ready since its a really dam powerful cans but yeah after listening to those level smth like phonix sounds lacking lul
I dont know why manufacturers dont start making amplifiers with 3 outputs for 3 way speakers, makes sense to me, as a properly designed 3way speaker will totally destroy 2 way for sound quality.
So I crept round the back with my torch and extra-strong reading glasses and, glory be, it does! I shall use it for my review of audiophile-grade optical cables.
@@AudioMasterclass Well i misjudged you. You obviously are like me genre blind i try not to listen with preconeptions and if its good its good. You are very self critical mind u in always putting my stuff down lol
the market is seemingly saturated with classd amps these days but I enjoyed the review, and even though the video of your desktop doesn't really illustrate any sound quality per say it was useful to see an example use for this type of amp :-) I see you have to pay more for an aptx bluetooth driver... an audiophile must ;-)
The unit I received did not function properly. I have contacted the company twice, with no positive outcome. Now they want me to send them a video of the unit in use. I just considered this a bad experience and pushed the unit to side.
SD cards are prone to failure plugging them in and out a lot. So, (because I also produce video professionally) I use them to record, then transfer to a computer, then wipe completely. If you don't, you'll get misreads eventually. And your hard work will be gone. The reader also needs to be treated with care. Any gunk, dirt and it falters. Third problem is: The SD cards, depending on how fast these are, are very expensive. While you can plug ANY drive into an USB slot. A gen 4 SSD with a thunderbolt 4/USB C on the business end? No problem. The USB port is much more suited for regular plugging it in. It's designed for that. On a job, the main thing is that it works, and keeps working. SD cards are fine for cameras, because of space requirements. But some pro cameras (Panasonic) are offering USB ports as well. So much for the fashion statement in the video. ;-)
Tricky to know. Sometimes I get what looks like either a pre-production sample, or something that some other reviewer has messed with. Call me weird but it's removing shrink wrap that bothers me most in the unboxing. Can only do it once so got to get it right.
David, get a junkmail address to set up the crap... I've got an old AOL email that has 193,000 unread messages dating back to 2006. The companies can pass that baby around all they want... Also, you do realize that you are being tracked every second of your life by location and sound already, so giving out an email address is the least of your worries...

Merry Christmas David.
I have had an ear worm all eve "I saw the bird and the bird saw me" lol can't get rid
I don’t think I’ve ever had a “ house guest” even notice my system, and I have a tube amp that is pretty noticeable. Goes for my wife also:)
And I don't know any other audiophiles. It's a lonely hobby. Ha ha.
I do like your sound example as it shows how the bass changes was a bit higher in frequency than I would prefer. Excellent review!
I am using this exact Amp with a pair of DALI OBERON 1 for my PC/Office setup and it is doing an absolutely fine job for this.
What was with the blinking indicator light?
Why I would watch you "unbox" is a curious pursuit I can't control...or maybe its your wonderful soothing voice....it can't be humans watching another open a box....something is going on here I can't see......haa
David is having a bit of a poke at the idiots doing "unboxing" videos.
Is that some skiffle version of "I fought the law and the law won"? 😁 Always a pleasure David, and never a chore! 😊
It's like having Paul McCartney and Eric Idle's test tube baby explain music to me with humor. The perfect love child.

So...should we buy it? I know I can decide for myself, but the esteemed comments of the Master or one his knowledgeable assistants would be welcome.
I simply love your style, keep doing this!👍🏻
I'm left wondering about the quality of the connectors... Something tells me not to (ab)use them too much...
The speaker connectors might be magnetic. Most of these cheap Chinese amplifiers have this problem.

That sound demo music was next level
I think comparison to fosi audio V3 would give a better hint of what we can expect in sound quality department then audio recorded on camera.
itll get there eventually, prob sound hasnt ready since its a really dam powerful cans
but yeah after listening to those level smth like phonix sounds lacking lul
May be not suited for audiophiles, but it's a good option for enthusiasts on a budget
I dont know why manufacturers dont start making amplifiers with 3 outputs for 3 way speakers, makes sense to me, as a properly designed 3way speaker will totally destroy 2 way for sound quality.
Does your TV not have an optical output? Every one in the states does...

@@AudioMasterclassmake sure they have gold plated terminators 🤪
You have good vocals.
Spotted Towhee is a bird native to western North America. They are common in my area of California.
Did I pronounce it right?
Yes! Excellent!@@AudioMasterclass
WOW, nothing but quality there
Entertaining and educative! Loved the episode. Would love an episode on subs! Thanks for the episode. ❤
The B&W DM100.... One of the most underrated budget bookshelves in British manufacturing history....
I do not like music clips. Just tell me what you hear and how well it works (tone controls and settings). Just my opinion.
Is that the new “saw” movie theme song “ I SAW the bird and the bird SAW me!”
And just when I thought you'd hit the sweet spot of annoying jingles you found a new one🤣😂
I hate this unboxing music 😏
It's just noise...not really music.
Totally with you
@namegoeshere2903 Agreed, speaking as an Audiophile.
Hint: You're supposed to.
Its an audio master class. That mean sound or tones use in this video is for measrement purpose only. 🤣
The unbox soundtrack was a real test, one I nearly failed.
The next one will probably have a greater degree of difficulty.
@@AudioMasterclass Thanks for the heads up.
it's got a rotary encoder volume control, blech
Powerbricks are evil, I'd rather have a box (amp) which slightly larger which then have a build in powersupply. The lack of s/pdif is just silly.
For some reason I like the unboxing music. To each his own I guess...
Who writes your unboxing music?
I do. It's all my fault.

Audio demonstrations are as useful as a chocolate teapot. (...and your song gets the bird).
The song is about mutual admiration. Or otherwise.
It's good to know that the reviewer got the same shoddy packaging that everyone else will get... Show's their honest...

Ouch!!!! That unboxing cheapomusic👎 ...otherwise, nice review as always, thank you.
Is the "beauty shot" ironic?...
Sound very much from the land of the giant panda.
😁
That music, if you call that music, is very annoying!! I had to skip over the unboxing part.
It's basically cheap shite that sounds crap, stick to your Sony ta-f300. Sorry if sound like an Audiophile, because i am an Audiophile.
pssst .... (Wispering) I wouldn't be bragging about that if I were you.

👍 for being a lefty, 👎for musical itinerary
Horrendous background music during the unboxing. Silence would have been infinitely better.
I fired the review off due to fekking annoying racket
Very annoying unboxing music(noise)
The intro music or better, noise is intolerable. Ty pical of so called audiophiles who really never listen to music.?
What was with that God awful unboxing music?
I would rather hear you talk about the amp as you unbox it. That music was unlistenable
John Darko, the audiophile reviewer, will be upset. That music (electronic) is his bag.
