    Great Little Amp.
  

*by F***R on Reviewed in the United States on June 9, 2016*

This amp sounds pretty good, all things considered, like price and size. I'm using this little guy to push a pair of Fisher 50 watt ported cabinets with 3 way crossovers. It has 0.04% Total Harmonic Distortion (THD) @ half power or 20 watts. I haven't had to push it near that to fill my 23'x20' living room. It does get a little warm, but not near what I thought it would get, but I still keep it in the open so it will run as cool as possible.My only warning is that you make sure your TV will let you control volume with its remote when using the optic out feature. I thought mine did, but it doesn't. I have a 1 year old Samsung Series 6, 50" LED "Smart" TV. I was sure that I saw in the documentation that I could control the volume when using the optic out, but I can't find the manual for it. Oh well. At this point, I'm using the Amp just for movies and set the volume manually and use the TV speakers to supplement the sound and control the volume. Works pretty good as I can still control the overall volume to a certain extent. I can disable the TV speakers, but by using them as described, I can semi control the volume (does that make sense? LOL).I am considering trying the HDMI Audio Return Channel (ARC) to a HDMI-Optic converter ($29) into the Amp, just to see if I can control the volume that way. In theory, it should work, but I need to do some research. Even with the extra cost of the ARC/Optic converter, it will still be cheaper than buying a low end receiver.If any one has a suggestion, please comment.

    Unit overheats and may have failed as a result
  

*by K***C on Reviewed in the United States on April 29, 2019*

My unit only lasted for a little more than 1 year, before it stopped working altogether. While it worked the sound quality was admirable given the size of the unit and the application was to drive TV digital audio through JBL in-ceiling speakers. The problems consist of not being able to power on or off the unit other than unplugging it. The need to unplug was due to safety concerns surrounding the unit getting very hot and wanting to place it in a concealed area. Further when unplugging the adapter from the unit itself, the connection arcs 80% of the time this exacerbating the safety concerns. It appears as though the overheating, the arcing or something else has caused the unit to fail. I will try connecting to a different speaker just to make sure it didn’t destroy the speakers or additional inwall volume control I have, but overall the unit may not be the safest in terms of its circuitry design and power management.

    Poorly designed
  

*by W***E on Reviewed in the United States on August 14, 2018*

This amplifier can not be plugged in to power continuously as it heats up and the sound disconnects until it cools down . Very inconvenient as the power has to be disconnected by pulling the power plug to the amplifier. No switch or remote to turn on or off. Very dissapointing , it works well for external speakers but trouble began shortly after using it on a full time basis. Not worth the money.
