I don't like the Auto-Switching inputs system, wich is too sensitive and keep switch between input 1 and 2 when there are quiet passages in music (on input 1). So I use only input 2. The same problem apply to the Auto-Sensing Power On, wich is useless for me.
Overall, it's a great buy for the price.
I've only used this amp for a total of several hours at moderate to medium volume levels, but so far its lukewarm temperature at worst remains constant on the heatsink vents at the top and bottom. That was one of my concerns prior to buying it, and I'm glad that it's no problem.
My sources are a laptop connected to an external USB DAC, which then connects to this amp. I haven't dared try playing music at 50% volume because it's already loud at the 3rd-4th volume knob's "dot". This is with 4-8 ohm passive bookshelf speakers, 90 dB sensitivity.
A few cons:
1) With my ears right up front to my speakers I hear a very small background "electronic" noise (not the hissing or humming noise), even when no audio is playing. Adjusting the amp's volume makes no difference whatsoever, even at its lowest setting. I thought it was due to my inexperience at setting up my 12 gauge speaker wires, but the same result occurs when I tested them with pre-made speaker wire that I've used with my previous PC speakers for 3 years. My previous speakers were dead silent up close. Only two 2 variables have changed since using this amp: the amp itself and the bookshelf speakers. I doubt it's my new Cambridge Audio S30 speakers that are highly regarded to be the culprit. Still, this flaw doesn't matter much since it's inaudible during practical listening positions.
[Update] - Upon closer inspection the same noise emanates directly from the amp, and it's slightly more noticeable from there than from the speakers.
2) At very low volume levels there's channel imbalance in the speaker output, with the right speaker being quieter than the left.Read more ›
The only drawback I see is that the "auto switching" feature (between channel 1 and 2) is a bit too insensitive, so there has to be a good amount of sound on the first channel to avoid switching to the other, otherwise the sound cuts off. Since I use it for music which does have soft sounds, the result is not that great. But I still think it deserved 5 stars because it works really well.

It shuts off if you connect your source to the wrong input. It is described in the manual but I had to search the Internet to find the answer and really understood the problem. Read morePublished on Jan. 31 2014 by Amazon Customer
This unit works great, turns on when the main amp sends a signal and then turns off when the signal stops, all automatically. Read morePublished on Aug. 29 2012 by Lyle E. Kerr
Received the product with damaged on all speaker B terminals. Good thing I only used speaker A input for my home theater system. Other than that, product works well for the price.Published on Aug. 1 2012 by Bhogs
