Small but mighty
As an person who’s used to high-end tube amps and large receivers, I wasn’t expecting much from such a small, affordable amp.No, it’s not going to replace your multi thousand $$$ boutique amp for critical audiophile listening or bragging rights, but for 99% of the population or normal TV, movie, game and music listening it’s awesome.I loved it so much that I ended up buying a second one.This little powerhouse easily drives my JBLs and KEF LS50 speakers to impressive volume levels with crystal-clear clarity. It’s perfect for my living room TV setup.The Bluetooth feature works flawlessly. I also appreciate that it comes with a remote. For the price, this amp is a steal. If you’re looking for a compact, budget-friendly amp that still delivers excellent performance, I highly recommend it!

Crazy good for the price!
Simple to hook to my bookshelfs (Wharfedale Diamonds) and Cambridge CD player. Amp is little; about the size of two packs of cigs. Excellent fit and finish. Doesn’t have the punch of a 40 lb amp but presents the music very nicely. 25% volume is plenty for me; 33% is about max in the family room I have it set up in. Excels on simple music like Japanese flute, cello, guitar, vocals; gets a bit congested on hard rock and similar but I bought it for the former not the latter, and my bookshelfs do best with the same. Bluetooth connected instantly and sounds superb. I’m very pleased with this purchase.

Better than my 10 lbs receiver.
It’s great for what it is, one wired input, one wired stereo output and bluetooth.You don’t need banana connectors, but the connectors are very close together so they are much easier than raw speaker wire.I picked this version because it switches over to bluetooth automatically and then back to RCA input when disconnected, so it’s wired to my computer most of the time but I can also easily play audio from my phone. The bluetooth PIN 0000 can’t be changed so anybody in pairing range can use the speakers unless you leave a device connected, but if you leave bluetooth connected you can’t use the wired input. So if you live near pranksters you might have to unscrew the bluetooth antenna. There’s a quiet click from the unit itself (not over audio) when it switches between bluetooth and wired.The sound quality seems fine. There’s some very quiet white noise hiss that may be from my other electronics or may be the amp, but I can’t hear it even a foot away from the speaker so I’m not even going to investigate. When connected, bluetooth has some minor pulsing noises that must be from the amp, but it’s quiet enough I doubt anyone could notice unless the room is silent and you’re close to the speakers.Kill-A-Watt said ~2 watts idle and I’ve never had it get more than ever so slightly warm at normal listening levels.

great little amp. does the job nicely
i got this to replace the final stage on the sony amp that blew it’s left side. the sony still works as a preamp and switcher for the turntable, tv and music streamer i have so i didn’t have to redo a lot of wiring. all i had to do was run a line from the tape-out on the amp and move the speaker wires to this little guy. all my controls and remotes stayed the same. nice bonus is i now also have bluetooth. it’s not as powerful as my original amp and you can’t drive it as hard; ive a feeling if you do, something will blow as the components are rather small. it happened on another, similarly built amp. the sound quality is adequate, esp in this age of earbuds. my wife doesn’t notice but i can definately tell there is a midrange bias, even with the tone controls. still, it’s good for it’s size.one thing i really like is the bluetooth addition. the sound quality is good and there is very little spurious noise. it is a preferential connection so it will override anything coming in from the AUX inputs. i wish there was a button to switch but as is, just turning off the bluetooth on your phone will cause it to automatically switch back.overall, it’s a good little unit. i wish it were closer to a $60 price point but build quality seems good and sound quality overall is great for this little guy. i’ll probably buy another one to use as a portable outdoor entertainment like another reviewer did.

I got this small amp because in bedroom I got a “cheap” chinese projector (1080p native) but audio is awful and very low. The bluetooth pairing works great and very quick without need to press any button. I had my mint Totem acoustic speakers laying since I moved last year so it was a perfect use. I dont listen very loud or hifi music in bedroom, only for movies/plex/youtube. But just a quick review to say that it is a legit good little amp, no static noise or pop,or anything bad. Would be the best if it had hdmi arc,i would have another use in others rooms and family.

Great little Amp. Dies what it’s supposed to do. Bluetooth connection was easy.

Sarà che va a pilotare delle polk xt15 ma l’amp conterà pure qualcosa nella qualità e per quanto è costato ha cambiato totalmente la prospettiva e le modalità di ascolto, potenza e qualità ad un prezzo accessibilissimo. Se come me siete entrati da poco nel mondo hi-fi non credo ci sia scelta migliore per iniziare.
