Opera Consonance Cyber 20, but for a slight background hum (hopefully soon to be resolved). Excellent soundstaging and sense of scale, less "veiled" and "grainy" than my old LD Mk. III (the LD was good for the price, though).
Perhaps it really is true that HD600s prefer output transformers to OTLs....
Nevertheless, I'm sure a Zana Deux will sound even better still - I have yet to hear this combination, though!
