Fosi AudioBT30D 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.

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 is a good amp. And i like the ability to output to a sub speaker. You can output to a passive or a powered sub, so that is good.But...It's hard to be sure where the noise comes from with this. Is it the power supply? Is it the bluetooth? But there is a noise that becomes more noticeable as you turn up the volume. (At a reasonable volume the noise is hardly noticeable)It would benefit from a switch to turn off the bluetooth receiver when not in use, as I think this may be the source of the noise.Hard to fully recommend. However, I use it. It sounds good. It's loud enough to annoy the neighbours. (Shame about the noise)

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.

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

Very good. Long range Bluetooth.

I run a very low noise floor audio interface into this amplifier with QED cables and clean power. The hiss when sitting in front of near field monitors makes it almost unusable and it will be getting removed from my system. I wanted the analogue sub output and for this it is very useful along with its size and bluetooth connections. Ironically it is the amplification part that lets it down. That said it is probably best of a pretty average bunch if you need such a small size.

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 :)
