Fosi Audio BT20A Pro 300W x2 TPA3255 Bluetooth 5.0 Home Audio Stereo 2 Channel Amplifier Receiver Mini Hi-Fi Class D Upgraded Integrated Amp for Speakers with Bass Treble Control

Incredible product, the sound quality is great over Bluetooth and the range is unbelievable. There’s also very little delay in the playback, so watching videos are no issue with the audio syncing nicely. The whole unit is so small which was very important for my space, yet performs well. I’m not an audiophile but I can definitely say the average consumer would be thrilled by the output, and not to mention the value for money over the competition.

I love this thing, and can't believe how loud it is! So one thing to mention is that you can't get the full 300w of power with the supplied power supply (32v) - they sell a 48v one I think on Amazon if you need that. Yet, the room I am in is 5m by 3.5m, and I don't think I'll ever push the thing past 1/2 way. Most of the time, considerably less than that. So the above does not bother me. It is powering some Cambridge Audio SX-50, and collectively they sound amazing! I briefly had some Edifier active speakers before this (cheaper, but not by that much), but sound comparison wise, there's no contest. So this is a pretty simple device - no remote, and not a lot going on controls wise, but having the two inputs (one physical, and the other bluetooth) is perfect for my needs. And the manual treble and bass are useful at times too. I've not got a sub plugged into this - for my needs, I don't think I need it (the speakers are pretty good without), so can't comment on that, but may add something in the future, so good to have the option. I'm using this for armature music production, and also for listening to music as I work, and its great for both!

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.

This amplifier is supplied with a 160 watt power supply so don't expect the full capability of power output from the chip. However, it produces more power than I'll ever need, I'm assuming approx 80 watt per channel. I'm impressed with the sound and the ability to play around with the preamp chips. The Bluetooth works with surprisingly good sound to my ear.

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.

Great little amp. Sounds just as good as a more expensive separate. I use it with old passive Sony speakers and a turntable. The Bluetooth works well. To activate the RCA connectors just disconnect the Bluetooth. Bargain

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 unit CONS - 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 therefore CONCLUSION It'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.

After investing days in the quest for the perfect budget amp to meet my needs, the choice boiled down to a decision between the Fosi BT20A Pro, V3 and the AIYIMA A07PRO. What ultimately swayed me was the feature offered by the Fosi BT20A Pro – variable control on an active bass unit. This addition meant not only managing volume but also extending its influence to the connected bass unit. With this distinctive capability in mind, I opted for the Fosi BT20A Pro. Despite not being a HiFi expert or having extensive experience with such devices, I find immense satisfaction with my current setup. Employing Polk ES15 speakers with an impedance of 8 ohms and powered by Fosi's included 32V 5A power supply, the sound quality is nothing short of remarkable. While I may not be able to pinpoint the exact impact of the amp on the sound, it resonates with crispness, and the bass packs an unexpectedly punchy surprise. Remarkably, I don't even have a dedicated bass unit for my small room. The overall build of the amp exudes solidity, and the volume and tone knobs operate without any discernible loss. I particularly appreciate the inclusion of tone control, a feature I hadn't anticipated using as much as I do. In summary, the Fosi BT20A Pro has exceeded my expectations, delivering impressive sound quality and versatile controls. For anyone in search of a reliable and high-performing amp, I can recommend the BT20A Pro. Cheers to a fantastic audio experience!
