I bought this to replace a Sony bookshelf stereo unit I've had for years that finally gave up the ghost. I used the Sony speakers and this little unit drives them just fine. It sounds pretty good. I had an old iPhone 8 I converted into a music player and now I can have my entire music library on the shelf. The FM radio function works pretty good too. It does remember stations with programs. Just make sure you use a good antenna. Overall, I recommend if you're looking for something to drive speakers and has input options. I just hope it holds up.

I love this thing! I have it hooked up on my patio running four outdoor speakers and it is loud, pushes plenty of power, Bluetooth works great, and can’t beat the price. Worth the buy.

The Sunbuck is small - which I want - and powerful enough to drive the bookshelf speakers in my office. The Bluetooth receiver works well, as do the line inputs I use for a Roku/TV/DVD combination. I have an old iPhone 6 (that isn't a phone any more) dedicated to music complete with my playlists. It's essentially a slightly updated iPod that also doubles as a clock, but the Bluetooth transmitter works just fine. The quirk in this receiver is that the built-in preamp is controlled by the remote That works for everything except the radio receiver, which (probably because it's just a commercial chip designed for something else) has its own preamp, which feeds its already amplified output to the system preamp. That can cause a loud surprise if you happen to switch to or even past the FM mode after using the remote to control volume with the power amp turned up with the knob. Not a deal killer, as long as you're aware of the behavior. Given the price, it's still a good deal for a small integrated receiver.

This Sunbuck Mini Amplifier is a perfect fit for my setup! Paired with a USB Bluetooth dongle on my KVM switch, it drives audio from my Windows 11 PC and MacBook Pro to desktop speakers via a Bluetooth amp. The 300Wx2 output delivers clear, punchy sound with no distortion, even at higher volumes. It’s super compact—barely bigger than my hand—yet handles RCA, USB, FM, and AUX inputs like a champ. Setup was a breeze, and it switches seamlessly between devices. For its size and price, this little amp packs a serious punch—ideal for tech lovers juggling multiple systems!

This is more like a 3.5 - 4-star review. This will do everything you ask of it. Bluetooth links up well, is small and compact, and puts out good sound. BUT, don't expect any depth to the sound and very low bass output. This isn't going to sound like a full-sized amp'd stereo, but yes it sounds decent.

I like the look and the size that's the main reason I chose this one over the others. Bluetooth works great, MP3 USB works great, FM signal pick up is good. The disappointment is the line input. It is very low and can only use 3.5 jack or RCA not both. I putting in my MP3 player on the line in and it's very low. You have to turn up the volume. Then if you change the mode to Bluetooth or FM the volume is very loud. Very annoying It's two different sound levels for the input and the FM and Bluetooth. The sound quality is good but the amplification is not there. I bought this cuz I wanted something small to put on my workbench to test audio equipment for reselling. If I would have bought this for personal use, I would be very disappointment with the input line. Update: stopped working so I opened up the case and found bad soldering joints on on/off/volume knob. Reworked the solder joint and it worked again. Bad quality control not sure, if the soldering was cold joints or something is heating up and making joints melt loose. I lowered my rating from 4 stars to three stars. Only because I know how to solder and I was able to fix it. Otherwise I would have given it one star. If anybody else has the same problem, just rework the solder joints under the volume knob
