I <3 the HD800s.
Could someone mention if using the computer as volume control would be horrid? I use Amarra.
My preamp is a GS-1 which has only unbalanced outputs. The Dynaudio MKII (as well as some other active speakers) has only XLR input. I assume that it would be better to use the balanced output of the my DAC (ECD-1) than to go use some unbalanced to balanced cable (assuming one could/should even do that)... but then I lose volume contol.
[i used to use the RCA input of the QUADs so I could use the GS-1 as a preamp but maybe I should have been using balanced cables and some other sort of volume control now that I think about it. ]
I know that I should really just get a GS-X and do things properly.... but maybe I should just buy one expensive toy from Justin at a time.
