Gee Unsound, that describes my system as of last week...
(Well, maybe not the "unlikely but surprisingly" part - and yes, it works fine :-)
I have previously posted the same thing Marakanetz is saying: despite the popularity of the tube preamp/SS amp pairing, I tend to think it's the power amps where placing tubes (power tubes) will give you the most of what tubes do that is distinct from transistors. But considering how fine your current SS system must be (and not understanding your qualifier about where the analog front end winds up) - and considering that what you're talking about is a second system, not a replacement - why not go whole hog if you're curious, and do a totally tubular new rig?
