Thanks for the fast replies gents (and ladies if I missed it). The serial indeed is just a few under 100. As for the source, it's a Dell with an I7 cpu and realtek HD soundcard. It has a mini spdif out capable of putting out 192khz, although the sound is noticeably different than 96khz and not in a good way. Best way to describe it is 'thin' (this is on the Mini-i btw). No big deal, I never listen at that rate anyway. Just testing all the capabilities is all.
I'm using DT880 with the D100. It's definitely on the clinical side (even on Sound 2) but I love how the classics are sounding. Plus I think I can take the edge off with a tube amp down the road.
Thanks again for the input. Very happy with my D100!
