Bob, I'm one of the few here that runs a tube amp and preamp in my two channel set up. Like Randy alluded to, some sound "tubey" and some less so. Slight alterations can be made by switching out tubes.

I find listening to tubes quite pleasing. Some equipment requires some sort of upkeep, like biasing, but I find it all part of the fun.
