Fosi Audio BT20A Pro Bluetooth Amplifier Hifi, 300W x2 Mini Stereo Amplifier with TPA3255 Chips, Replaceable Op-Amps, Bass and Treble Control, Class D Amp 2.0 Channel for Home Audio Outdoor Speakers

PROS- Drives my 100W speakers beautifully- A very discrete unit, fits in the palm of your hand- Easy to plug in and conceal if necessary- The case has a really good feel to it- Nice design and smooth corners- Has subwoofer connection to add bass should your speakers/setup require- Bluetooth connectivity excellent even when going downstairs with mobile in pocket (2-floor house)- Being able to disconnect the paired bluetooth device is a brilliant idea- Blue LED showing Bluetooth is paired- Red LED showing power on- Power adaptor has perfectly acceptable size- Midpoint knobs for treble and bass, allowing setting these at zero (brilliant feature)- Bass and treble controls produce excellent results in sound- Red volume knob of larger size- I'm sure there are many technical reasons why this is an excellent unitCONS- I do not have any issues with this product.SUGGESTIONS:- Provide rubber feet to install the unit vertically on its side (however anyone can get their own rubber feet or even velcro straps/adhesive velcro straps thereforeCONCLUSIONIt's hard to think what else could be improved with this product (maybe create 10 or 15 case colours to suit the needs of customers whose audio setups need to sound as good as they look).I'll get rid of my Cambridge Audio amplifier as soon as I can because it's simply no longer necessary to have something of that size to drive my audio needs.

Having had a few different hifi setups in my time, I am pleasantly surprised by this latest purchase.I'll list some pros and cons and then give a bit more information about this Fosi Audio amplifier.Pros:- Size: I have a Denon amplifier and Mission bookshelf speakers. The Denon amplifier is amazing, but it's large and I haven't had enough space to put the amp and speakers together on a surface. It's probably the main reason I bought this product. It means I can still use my lovely mission speakers, and the speakers and Fosi amp all fit on a surface I have free.- Sound: If you are getting this, having never had a proper amp+speakers hifi setup, it's probably going to blow you away. The sound quality is very impressive for such a small unit. Having the treble and bass controls are a nice touch. Pair this little amp with some decent speakers and you'll be happy. For the price and considering the size, it's wonderful.- Bluetooth: Nowadays, for the sake of convenience, I use Bluetooth for my music often. Music does sound very good simply streamed from my phone through Bluetooth to the Fosi unit. There is an RCA out for any peripherals (such as a turntable or cd player etc). I haven't had any issues using the Bluetooth.-Build: The unit is made of metal. I've read some reviews mentioning the switches felt cheap or loose....maybe I'm lucky, but mine is fine. Great build quality and sturdy controls and ports.Cons:I can't really think of any. My Denon amp is a fair bit better than this unit in terms of sound and power output, but buying a new amp similar to my Denon unit would cost in excess of £300. And there isn't exactly a huge difference between them.This amplifier got my wonderful Mission speakers back into action and since I've had the amplifier, it's made listening to music really exciting again. I'd say it's good enough for bedrooms or small living rooms. If the room you have it in is particularly big, you may need something a little more powerful. Having a remote control would have been a nice addition.Ultimately, im really impressed with this. It's a quality audio product for not much money. Pair it with some quality speakers and you won't be disappointed.

Stayed at a friends house couple of weeks ago & he had quite a large Cambridge amp cost around £600 great sound from it but out of my budget ! Then I found this little gem of an amp ! Great sound & very easy to set up ! Even if it lasts only a couple of years cannot complain about it due to the great price I paid for it ! Wired up to wharfedale 9.1 diamond speakers & it’s fabulous ! 👍

Lovely design, clean sound with lots of power.I would have given this item aa 5, but the style of volume knob the company uses has quite alot of play in it, ie movement.I have contacted the company, and have been assured this is normal, yet I feel this could have been a perfect product if it wasn't for this niggle.I'm not nit picking, as an internet search will reveal others who have mentioned this issue also.So it's a 4 from me.

Used as a desktop system with Mp3 player (wired) and a soundblaster dongle from my laptop. I have a set of vintage Canton 4 ohm speakers that are efficient connected with banana plugs and pure copper wire. I am using the 32v supplied power supply.I almost returned this as when I first started using it the treble range sounded distorted and overall the amp sounded thin. Fast forward to around 20 hours use and the little Fosi is revealing itself to be a very capable unit. The separation, clarity and reserves of power are now all evident. The control through the range is now very good , excellent bass and clear treble. The tone controls work well allowing acurate amounts of adjustment if needed.Connection: Sorry I don't use bluetooth but I expect it works well. The 2 phono sockets are fine to use with whatever you plug in.The 3.5mm pre out: Disappointed with this it would not send anything to my powered sub, not a deal breaker but research on the net shows this is a common complaint. Fosi should have put a dedicated sub out for this.The build quality is fine and with the 32v supply only ever gets slightly warm. I have also read that the alternative 48v supply causes the amp to run quite hot. The output for me is enough and I can listen clearly in the room away from my desk.Apart from the issue with the pre-out I can still give 5 stars due to the overal qualities of this little amp.
