Stforth,
I had Don Sachs upgrade all my Harman Kardon Citation gear (I, II, and V), but his preamp is vastly better than the upgraded C-I. Don is a genius with both his tube preamp, based on 6SN7 tubes, and his KT88-based amp. In my experience, his tube gear gives one a glimpse of high-end sound at a fraction of the cost of major audio companies. Send me a PM and I will be happy to chat with you about the preamp.
I have fooled around with a boatload of modestly-priced cables, but really like the Cerious Technology graphene cables, followed by Silnote and Shunyata. I could hear more difference in SQ swapping the various IC's and power cords than I have with the 4 DACs I have auditioned. Cheers, Mark
