Fosi Audio BT30D Bluetooth 5.0 Stereo Audio Receiver Amplifier 2.1 Channel Mini Hi-Fi Class D Integrated Amp 50 Watt x2+100 Watt for Passive Speakers/Subwoofer Powered Subwoofer

Perfect little amp. Stylist and functional. Ideal for my needs. I have it hooked up to a pair of old Pioneer (100w) speakers, plus a Polk subwoofer. The units MAX Power Output: 50W x 2+100W.The Bluetooth is fine, and the connection was quick. It does from time to time drop out, even when my mp3 player is only 2-3 metres away, but in the main its stable. I have notice though, that using my other MP3 player, which is an iPod touch, then I get no drop out. Its very loud when I want it to be, I control volume via the mp3 player.Good sound for me, but I’m not audio master. It packs a punch for such a small amp, it handles my speakers and sub well.I would definitely recommend this unit to my family, friends and colleagues.

Nice sturdy little box with dials feels like an amp should should just tiny. Sounds great with connected echo input or phone over bluetooth certainly no worse than entry level '90s predecessor. Comfortably drives more volume than I need to annoy neighbours from a pair of 8 ohm mission bookshelf type speakers.I now have lots of space and removed nagging feeling I was burning £5 notes using the old one even if it takes about 10 years to pay for itself.Negatives, the bluetooth arial dwarfs it and rather ruins the lines could be useful outside.No L/R balance but something I don't use.No way to prioritize line-in over bluetooth and have to tell connected device to disconnect.But for the money cannot complain about minor compromises (£84 deal) so still 5*.Probably would have gone for model down without the sub out but at the deal price this was cheaper at time.

Remarkable sound for the cost (after a few hour use to burn in) I hooked this little thing up to my Monitor Audio Silver 200' floorstanders and using a good source like my Cambridge CXU into the phono's and playing CD's this unit provides a surprisingly wide spacious sound stage and good solid bass rhythms, the bass goes deep as well and sounded like it actually had more low end clout than my £1500 hifi amp, the sound gives good bite and texture to instruments making strings, violins and cello's etc sound very real, I was shocked how good it sounded tbh.Of course all is not perfect (lets not forget its and 85 quid mini amp) and where this little digital amp falls down is on refinement to the music, it's a little course and hard in the treble quality and lacks the fluid creamy sound of a good hifi amp so it's certainly not a substitute for a good hifi amp but as a bedroom setup or for the computer it's excellent.I then connected it to my THX soundworks computer speakers and 8 inch passive sub and again it proves excellent with more power and punch than I will ever need, even with the standard power brick it has lots of usable volume.Bluetooth sounds just OK as you'd expect and the signal is stable BUT the major flaw in this unit is ANYONE ELSE CAN CONNECT AND PLAY MUSIC OVER IT via Bluetooth WITHOUT your permission as it does not have a pair button or ask for a code on your phone, this is really stupid and why I have only given 4 stars.

Typical Fosi product Works well simple to use, small and compact with good Bluetooth connectivity sounds very good for the price.

Pleasantly surprised by how nice this little amp sounds! Bought it to use on my PC for music etc.. Hooked it to a pair of Denon bookshelf speakers and a Pioneer passive sub and the sound is great. A few little tweaks to the sound adjuster knobs on the front and its sounds lovely.One thing to note that using a 3.5mm to RCA from my PC's motherboard, the volume is crazy loud! my PC's volume bar is on 40% and its more than loud enough. The volume knob on the amp isn't even quarter turn.. So just be warned if using with a PC.Otherwise.. a top piece of kit :)

power ratings are not RMS but peak,and on stand-by ,and impressed onto your audio is 50 hz from PSU ,IA ran an earth lead from amp to my PC,That cured it and ferite clip on filters on AF input.

Great little amp. I paired it with Klipsch R 41m's and it can shake the room when pushed no distortions that I can hear, pretty amazing. It does have some static noise coming out if you crank up the dial with highs but its only audible when you dont play anything; when music is on you cant hear it. I cant say anything about the sub output since I dont have a sub. The bluetooth connection works great. Great value for money no regrets whatsoever.

It's a wonderful amplifier, but from day one power socket is lose, I thought it was on floor, that's why breaking so 9ften.but I changed the power source/adaptor but I learn socket is loose, I put sticky tape on it, it's still bubbly
