I've been able to listen to the amp for a few hours and it's been pretty impressive so far, it brings out details in songs i wasn't able to hear with my previous setup (PC as a source on a M-audio 2496 soundcard direct to my AT ATH-A900), bass are nice and tight and guitars are a real joy to listen to. At times you have the feeling the group or instruments are right in front of you, sometimes a tad too much on certain songs but it may be due to the fact that i use closed cans, or poor audio enginering from the disc makers.
I have a few questions:
1) I have a slight hum even at low volumes and it becomes really present when i turn the volume knob a little more than half way up(3/4), is it possible to get rid of this or to make it less present?
2) Is it possible to implement a source switcher like in the following pics
3)Would cat6 cables be better between the RCA and amp input than the cable i'm using?
4) Temperature inside the case is 122°F (50°C) is it ok or should i add ventilation holes on the case?
5)There is a pretty loud snap (clac?) sound that goes thru the cans when i power down the amp is it normal, or should i remove the jack plug before powering down?
