BT20A PRO

Excellent and well priced amp, paired with Cambridge Audio SX50 speakers and Minx x201 subwoofer. Good output even with the 32v PSU it comes with, there is a 48v PSU upgrade. Very clear and detailed and drives the speakers without issues, dispite its small size, which means it can be placed discreetly in any room. You can swap the opamps if you wish to tailor the sound, but I'm using the factory fitted ones which are fine for me. The press and hold the volume button to clear the current BT connection is useful and well thought out feature. Excellent value and performance, would fully recommend and will be getting another for another room, which this was intended for but never got past the lounge.

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.

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.

For something so small and inexpensive, as a real hifi fanatic, I’m super impressed how good this sounds driving some elderly bookshelf shelf speakers that came with an old Denon systemYears ago. Now, it’s not hi res WiFi streamed tidal audio quality, But for streamed audio over Bluetooth, it’s truly superb. An absolute bargain and sooooo tiny.

I have some Q Acoustic 2010's which are of quite low sensitivity (86dB) and need some power to wake them up and sound good, the Fosi does this well. It's nice and small for my desktop setup and looks and feels really well made. The bluetooth function is handy too but I use it connected to my PC mostly.

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!

JUST GET THE BT20A! NOT THE PRO. Save yourself the extra money. Unless you NEED the higher power rating.I have owed both the BT20A and the PRO so here is a detailed breakdown on what the two can offer. Prior to owning this I had the BT20A. I enjoyed the metallic black colour and clean silver detailing. It gave a very premium feeling for the price you paid. However I had experienced a very loud buzzing which I assume was a fault with my device. Upgrading to the BT20A PRO fixed this issue but I feel like this is the only benefit it provided as compared to its former counterpart.The Bluetooth feature is problematic… The BT20A would only connect to devices when specified and allowed the user to fully control over the use of this feature. Now with the BT20A PRO, whenever the amp is turned on it will connect automatically to any paired device with no option to disconnect unless you manually turn off Bluetooth pairing. If a neighbour was to accidentally pair to your BT20A PRO there is no way to unpair the two devices from your control. And you would have no idea that someone else has paired to it either. Atleast with the BT20A all you had to do was turn the device off which would unpair all devices until actively re-paired. Now with the “PRO” you’ve have lost control as it chooses itself when to pair to a device. And it will pair to anything that has established a connection prior. I had tried removing the antenna but it seems that doesn’t stop the connection issue.The build quality is also unimpressive; one of the knobs on the AMP is loose and jiggles (see video)- something I didn’t have to deal with on the BT20A. This is something that wouldn’t bother me had I known less. But once again this seems like a considerable DOWNGRADE in build quality compared to the BT20A. However I do enjoy the locking mechanism that the dials have at 12 O’clock position. Ensuring that you are listening with standard EQs that studios intended for vinyl playing.The size is small, compact, and fits well to my needs on a limited surface. I thought something so small would have problems with shielding. This is not the case. Shielding also wasn’t a problem for the BT20A.The power rating allowed me to upgrade my speakers which is also very nice, but for vinyl listening, I would never use full volume. However the AMP came with a 32V/5A power adapter despite being rated for 48V/5A. Meaning you’ll have to purchase one yourself.The sound quality is amazing across both AMPs so either choice you make you will be satisfied.Overall, I am very happy with this purchase and that it has fixed the issue I was experiencing with my faulty device. However had I not experienced the issue I would have been very satisfied with just the BT20A.

I bought this amplifier to pair with my Sonos Port so I could use a set of Yamaha outdoor speakers, and it's been exactly what I was looking for. Setup was quick, and everything worked perfectly right out of the box.The sound is clean, powerful, and distortion-free, even when turning up the volume outdoors. I also like the compact design, it looks modern and doesn't take up much space in my media cabinet.I've had zero issues with it since installing it. If you're looking for an affordable amplifier to add passive speakers to a Sonos setup, I highly recommend this one.

I am incredibly impressed with the Fosi Audio BT20A. Setting it up was an absolute breeze, taking only a few minutes from unboxing to playing music.It integrates seamlessly with my turntable setup, delivering clean, crisp, and punchy sound that breathes new life into my vinyl collection. The ability to switch over to Bluetooth streaming is a game-changer. The wireless connection is rock-solid, has great range, and makes it effortless to stream playlists straight from my phone.For its compact size and affordable price, the sound quality and power output are remarkable. It fits perfectly on my shelf without cluttering the space. If you need a reliable, budget-friendly amplifier that handles both classic analog vinyl and modern wireless streaming without any fuss, this is the one to get!

Muy contento con el producto. Es muy versátil, tiene potencia de sobra para unos altavoces medianos. Al ser pequeño es muy transportable, y me sirve tanto para escuchar en casa a bajo volumen (la señal de ruido es imperceptible), como para llevarlo junto a los altavoces a espacios más exigentes (pequeñas fiestas). Aquí el limite lo tengo en los altavoces, porque lo que es el amplificador funciona más que de sobra. Y el bluetooth es un extra muy útil, porque tan solo con unos altavoces y un móvil con música te montas un equipo potente para llevar, y suena muy bien. Me es útil para ir poniendo música mientras conecto el resto del equipo. Los potenciómetros de graves y agudos son también útiles. Y bueno, su precio económico es factor decisivo para toda la calidad y prestaciones que ofrece.

On peut vraiment obtenir un rendu qui correspond à ce que l’on aime et c’est un vrai plus.À la maison, tout le monde est content. C’est devenu un petit élément indispensable pour profiter des beaux jours, des repas dehors ou des moments détente en famille.
