4.0 out of 5 stars Good little amplifier. January 16, 2012

Solid build quality(*), very good sound, and highly efficient.
I've just replaced my trusty Sonic Impact amp with this one, mostly for the heck of it.
Hooked up to an M-Audio Audiophile 2496 and JBL Control 1x speakers, my (slightly modified) Sonic Impact has been (and still is) a great little amp. When measured using the Dayton OmniMic measurement system, it recorded a perfect straight line except at the low end where the speaker simply did not produce anything. The lack of very low frequency response is, of course, expected from a set of small monitor speakers.
This amp is no worse, which is to say, it sounds great. In fact, this sounds a bit better than the Sonic Impact I've been using, but that could just be me being happy to get a new toy ;)
(*) Now for why I subtracted 1 star.
(1) The case is painted. It is not anodized. Properly anodized aluminum surface maintains its positive properties (good heatsink), whereas painted surface does not. And anodized surface looks better, too.
Does it affect performance? Nah. It'd never get hot enough to matter anyway. I'm just complaining because I expected to see a beautifully anodized black case when I ordered it.
(2) Another issue I had was, out of the box, left channel did not work! Needing to return it was not making me happy. Then I thought maybe the relay for the headphone connection was stuck, so I plugged in a headphone and then unplugged it. Voila! Both channels came alive. Kind of makes me wonder about the quality, but oh well, stuff happens. It hasn't done anything funny after that, so I'll just try to forget the initial glitch.
