5.0 out of 5 stars Great little amp that exceeds expectations considering it’s price.
By Mark Leon on 30 March 2021
Great little class D amplifier for the price. I e got it driving two old bookshelf speakers and I’m really happy with the results.

It’s lively and has a little punch but I wouldn’t believe the quoted 100rms personally... still, if that’s the kind of power you need to drive your speakers, you wouldn’t buy this amp anyway.

The bass and treble dials do what you’d expect them to and Bluetooth seems pretty consistent.

5.0 out of 5 stars Stop wasting time and just buy!!!!
Reviewed in the United Kingdom on 31 January 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 29 November 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!
