Tom, I would never own a solid state preamp OR amp, so I guess I'm into this "tube richness" thing, like it or not. We're obviously talking semantics here -- your "richness" becoming my "coloration," when we probably mean much the same thing about why we like listening to tube gear. Well, some tube gear in my case -- maybe midway between the older tube stuff and SS.
Bottom line: I had the CT6 in my system for a day and was monumentally underwhelmed, compared to my then-preamp, the Prem 17LS2. The CT6 listed for exactly the same amount -- $4500 -- as the original Premier 17LS, while the Premier 17LS2 upped the ante to $6000, the difference being mostly the teflon caps. Sonically, as the reviews indicated, they were in different leagues.
