Fosi Audio BT20A Pro Bluetooth 5.0 Amplifier, 300W x2 Wireless Amp, TPA3255 2 Channel Mini Class D Integrated Home Audio Outdoor Stereo Receiver with Bass Treble Control for Passive Speakers

Excellent upgrade from Kinter K2020a+
After my big ‘stereo down size’ about 6-8 years ago, I ran my streamers into a Kinter K2020a+ and a Polk Audio shelf speaker set… and I was as happy as a kid in a candy shop. Recently I sensed one of the channels was beginning to get a little less clean and decided to cast around for an upgrade. I actually had the next model down (BT10?) in my basket, read about the more powerful BT20 Pro, and made the leap. Glad I did!Product is elegantly packaged. Bluetooth connection was a breeze. Press the volume knob for 5 seconds to disconnect BT and connect to another source. EQ is simple and effective. I truly dig the way under stated light gray steel appearance, Power switch and 3 knobs on the face. Device feels solid. Dual speaker connection types, easy to hook up. Less is more.Proof is in the pudding – the sound.. and it doesn’t disappoint. Versus the Kinter (which, of course, does not punch as many watts) it is clearer and deeper, and, if you want, much louder. For me the key is clarity at a lower volume (I am running it as sound in a modest art studio). Whether it is piano jazz from Fergus McCreadie, new acoustic from Halaiker, experimental from Ezra Feinberg or African string music… it all comes thru in great style. It will rattle the windows if turned up, but I really love the clear almost analog sound of all my genres at medium to low levels. Great stuff and worth the modest $ upchrge.

Great partner for pair of 60W 8ohm vintage speakers
I bought this to use as a “loaner” setup to lend to a friend who doesn’t have her own amp/receiver, and before I let it go I hooked it up to my vintage Sansui SP-1200 speakers.I don’t think I am going to loan it out after all 😂Nice little unit which takes up much less space than a full sized receiver, which is really handy if space is limited or you’ve only got one main receiver & speaker setup, but want to use some other speakers elsewhere. It would be very portable as well.It has a very solid build quality, it looks and feels well made. The body is metal and so are the knobs and switch; none of the parts or pieces feel chintzy to the touch.My Sansui SP-1200s are 3-way, 5 driver speakers which include a single large ~10” ported sub, 2 mids and 2 tweeters. They are rated at 60W power input, sensitivity of 92dB, 8ohms impedance. The amp makes these speakers SING! Music listened to so far has been (volume cranked) Marcus King, The Teskey Brothers, local fave Ty Pow & The Holy North (do yourself a favor and look them up), Led Zeppelin louder than is comfortable for my ears, some Tribe Called Quest (bass is nice & clean, vocal clarity also good, full range of sound) as well as some jazz and classical (softer volume, lol).My speakers were able to handle the amp turned up pretty loud as well; volume at the 1 o’clock position was comfortably loud filling a living room, 3 o’clock is about as loud as I ran it and you can feel the music in the floors. (For reference, min volume is at 7 o’clock, increasing clockwise, with max all the way around thru 12 to nearly 6 o’clock).Speaker wire inputs look like they are only banana jack ready from product pictures, but they also unscrew to accept a bare speaker wire or a pin-type wire end. I got some of the screw-on type banana ends to put on my bare wires. Fit is nice and tight in the plugs.Note that the power supply which comes in the box provides 32v, and as another customer mentioned, you won’t get the full 300W output without purchasing a 48v power supply.Related to this, the output rating of 300W is into 4ohms, so with speakers like mine rated at 8ohms impedance, the amp will output approx 150W.It should also be noted that if you’ve got some bookshelf speakers or other small speakers which can’t handle the power output (rated power handling of the speakers, and impedance, should be listed on the back of your speaker cabinets), you can use this but you’ll have to keep the volume turned down so you don’t blow them. The amp says it is rated to handle “terminating impedances” from 2-8ohms. Most speakers will be between 4-8ohms.Happy listening!

Ik ben echt wel tevreden over deze versterker. Had eerder een Marantz versterker van de jaren 70 die ook wel een goede klank gaf maar soms kraakte, niet te vergelijken is qua grootte en waarschijnlijk ook veel meer verbruikt.Maar het belangrijkste is en blijft de klank en daar ben ik tevreden over. Qua volume weet ik het niet want ik heb geen nood aan erg luide muziek.

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.

My Marantz PM14 broke down, bought this as an intermediate awaiting repair. I really am not sure I want the Marantz back. This is THAT good. Incredible transparancy, excellent lows. Lacking multiple inputs and remote, of course.
