Hi Dave,
Not technically the D-200's, but I am using thier 1st cousins, some mildly upgraded 8620 buffered Hypex 400's... the next best thing!
I had Lonewolf's Modwright 9SE in my system for almost two weeks and have to agree with Freejazz, it is a magnificent combo! What I'm actually using...
Response Audio moded Ming Da preamp or
Django tx-102 autoformer preamp
Salk Sound HT-3's
VenHaus Pulsar IC's
Jena Labs TFA cables, soon to be tried/replaced by Gregg Straley's?
