I spent months searching for the right Bluetooth receiver/amplifier that could sit inside my pool house. This small unit has it all! I ran it for hours (not at full volume) when the ambient temperature was 85-90 degrees F. The case has no vents so it will keep most outdoor dust/dirt out. If you are serious about your audio sound quality then you already know you MUST have a dedicated subwoofer speaker channel like this amplifier provides, even for a low watt device. Don''t waste your time buying a cheap amp that doesn''t have a subwoofer channel with its own independent gain and frequency control. This amplifier gives you outstanding subwoofer signal flexibility so you can match the output to your existing speaker (passive or active). In addition the unit gives you bass and treble adjustments for the main speakers. 3 methods of input: RCA level jacks, Bluetooth, and USB drive. I can''t wait to use the level subwoofer output channel (RCA jack) when the time comes to send to another amplifier. The Bluetooth range is OUTSTANDING - I stopped testing the signal when it was still working at 75ft! The knobs themselves are top-notch quality. The speaker studs are also quality pieces and rock-solid. The remote seems to work well. Be aware the rated power output (main speakers 50 watts*2 + subwoofer 100 watts = 200 watts) is a "peak" number. Continuous power output is most likely closer to 90 watts based upon the rated output of the AC/DC adapter (19V * 4.74 amps). Regardless the unit sounds great. As stated in the headline of this review, this amplifier has just about all the features you could ever want in such a small package, for an affordable price. You will not be disappointed!

Bottom line is a small stereo amp/receiver with so many features, good for small space with USB playback and Bluetooth connectivity. There was no review available when I bought this for my gaming PC audio use, so writing one:
- uses Texas Instruments TPA3116 power amp IC, capable of 50 watts per channel in stereo. See TI''s datasheet for complete details if interested.
- uses 2 x TPA3116 ICs - one to power Stereo (2-channel, 50watts x 2) speakers and a separate one (100 watts) to power passive subwoofer.
- you can connect active/powered subwoofer via subwoofer pre-out, or passive subwoofer with its subwoofer speaker terminal. Subwoofer freq. control is very useful for proper integration.
- tone control (bass/treble) in front along with volume control and input select.
- comes with remote, don''t know if universal remote could be used though.
- not super powerful, I just connected with floorstands but will move to my gaming PC with small bookshelf speakers and active subwoofer.
- build quality is nice, looks good too. 4mm banana plug fit nicely to speaker binding post.
- Sound is clean within its limits.
- did not too warm to touch running loud for hours, came with AC/DC adapter power supply.
- can be used just as stereo desktop amp with 2 small speakers, or 2 speakers + 1 powered/active subwoofer (recommended with supplied PSU), or 2 speakers + 1 Active/powered Subwoofer + 1 Passive Subwoofer (but upgrade PSU if possible).

Considerations:
------------------
- just 50 watts per channel, so good enough for small bookshelf speakers. Adding a subwoofer is easy and adds missing piece in overall sound.
- mine came with 19v 4.74A AC/DC adapter - 90 watts in total. You can get 24v PSU if need more power, but not needed at all if not using passive subwoofer.
- small size and so speaker terminals are close to each other. Be careful if connecting bare speaker wires, avoid strands touching amp chassis or other terminal. I would highly recommend buying banana plug for clean and risk free connection.
- came with remote, but just good enough quality and not bad for the price I paid.

Overall, not so powerful but a useful amp/receiver for small space with loads of inputs and subwoofer connectivity.
Good enough for a small desktop/computer audio setup.

First off, I don''t reviews like many others but I just had to take the time to share my thought on this amp. Let it be known that this was my sixth purchase trying to find the right amp for my desktop. This amp has features galore that will challenge even the most critical listener. With my setup of the Polk Audio TL1 satellite speakers and a six inch Kanto subwoofer, I''m here to tell you that at this amps price point you''ll experience a sound stage that will impress anyone who listens to it.

At 50 watts a speaker channel and 100 watts for a passive woofer as well as the features that include subwoofer adjustments on the front panel so you don''t have to have to adjust the subwoofer from behind the unit which to me is a real pain....this makes it a pure winner to me.

The sound is pure and warm either listening to stream music, cds or usb drive. Check it out and don''t hesitate to buy this unit.....My sixth purchase was a charm. You won''t have to do this as I took all the hard work out of your purchase for you. You will a delighted listener !!!

I''ve used it on and off for about a month and so far I''m pleased with it. I''m using it with a pair of Sony SSCS5, this is my first amp and I don''t have any others to compare it with but so far i"m happy with it.

Bluetooth:
The connection has been reliable even 15ft away with 2 solid concrete walls between my phone and the amp.
Haven''t noticed any loss in audio quality switching between the aux and bluetooth inputs.
I''m getting about 50% of the max volume of the aux input from my PC when using the bluetooth with my phone, but that has been more than enough for me, I typically keep the bluetooth volume between 70-80% for loud but comfortable listening.

Aux:
Initially I was hearing some static even when no audio was playing, which wasn''t present while using bluetooth, but that went away after replacing the old RCA cables I was using.
I''ve noticed that the volume resets when the unit is switched back on, which was annoying at first but quickly got used to it after it saved my eardrums when I forgot to readjust my PC volume after testing how loud the Sony SSCS5 can get (which is insanley loud if you are in a small room).

Not Tested:
USB input, Sub output, Remote.

I saw complaints about switches quickly failing for the other models from this company, which is why I bought this one. But no issues so far, will update if anything changes.
