No apology necessary, but I'm pretty sure mine is working just fine. It drives my MS-1s quite well (though not to painful levels to be sure). Really couldn't drive the K501s well at all, not just too quiet but also no punch. The 501s normally get driven by a Little Dot Micro Tube, which does very well, so I have a good idea what they can sound like.
I suppose it could be my source but I tried several tracks, all using Music Match. I haven't leveled the tracks as I've read mixed comments about mp3gain.
I'd be willing to try something else to verify my results though. Personally, though I am very satisfied with the 0404, I was surprised that I have to crank the volume almost all the way.
