5.0 out of 5 stars Stop wasting time and just buy!!!!
Reviewed in the United Kingdom on January 30, 2020
I wanted to power my Wharfedale Diamond 9.1s, but my AV receiver was too large so I took the plunge and bought this mini class D amp. OMG wow this amp makes my speakers sound better then my Onkyo amp!!! As an audiophile, I am quite fussy about sound, but wow this is the best thing I did! I Bi-wired my speakers and they sound great... I recommend using banana plugs for superior sound.

The only thing missing from this wonderful amp is a remote, so Fosi Audio if you are reading this, please produce a remote for your amps it would make the experience absolutely perfect!

Anyway so far so good! Definitely will recommend to anyone, its a god send!

5.0 out of 5 stars Hifi sound at low-fi prices
Reviewed in the United Kingdom on November 28, 2020
Considering the price and size of this amp, you will not believe the hifi quality sound it produces - crystal high frequencies, tight low end with strong mids. The bluetooth connectivity is great.

I originally bought some expensive PC speakers to play my hi-res music from my MAC while I'm working. They were pants!! So I thought I'd look for a hi-fi solution. Worried about what I would get on a budget, I luckily found this amp along with a pair of entry level Wharfedale speakers. Reviews for this amp were extremely favourable so I bit the bullet. I am so glad I did.

This is a PERFECT solution for what I needed. Hi-res hi-fi sound from my MAC. I think anyone who buys real hifi products would be extremely surprised at the performance from this little unit. It wouldn't replace my full hi-fi amp but it is not far off.

If you are on a budget and need sound from your MAC or PC, forget the range of 'computer speakers'. Most of them are poor. Get this amp and some decent hi-fi speakers. You won't regret it. I am stunned and over the moon with it!
