Mighty Little Amp...

I searched quite a few manufacturers in a quest for a nice, detailed small Amp for my desktop. I'm running a Wiim mini as my source and out putting to a pair of older JBL L1 bookshelves. So very impressed with the sound of this setup. I appreciate the tone controls on the A5pro. Just enough to tailor music like I like it. Excited to do some Amp rolling but I'll leave things as is for a month or so to fully appreciate the sound first.. and it sounds fantastic as is!
Thanks Douk

Excellent amplifier

Your amplifier is excellent.
It is harmonious, transparent with very good separation of the instruments and a serious sense of stage and noiseless too. OK i don't like the character of TPA 3255 but this one gives much more than expected. It lets you understand the recording and the playing of the musicians.
Sturdy construction, too, in an extremely practical and beautiful doric box. I suggest it

Great amplifier for for my television

Ok I bought this amplifier to get better sound from my television. I've used Aiyima audio t4, Fosi A07,and bt20a. All sounded good. Like a lot of people i just can't leave things alone. But to this amplifier. I have been running this since July with the 48v 5amp power block. It is January 15 and I am switching power to a lower 32v 5amp. I hate to say this but it does sound better on the lower voltage. Not so strained I think. You get more power with other power block, not necessarily better sound. The main reason for the change was that this amplifier was running way to hot. Lower voltage running is much cooler. Still sounds good to. I think it will last longer to. I recommend not buying the higher voltage unless you really need the power. Found out I didn't.
I wouldn't hesitate to buy another one ,it does sound really good.
