Kbuzz,
That was a very generous offer. :)

I actually got the chance to hear the Mk1 yesterday in my system. It was a little tube-ey if that makes sense, sort of thick around the middle and a little rolled off the top.
I note that you are using Purist Audio Museaus cables. You do realize that you just described their sonic character too, don't you? I do understand that you may want to buy a more revealing preamp, so that you don't have to change cables too. Given that situation, you may be searching for a ARC, VAC or Aesthetix, though I doubt if you could get an Aesthetix in your price range.
