The answer is really difficult to say for sure. Mismatched equipment can happen regardless of purity and some combinations just flat out sound bad. The good news is you can play around and find out for yourself - since most of us color our solutions on what sounds best to us there is rarely a holy grail.

I have a very pleasant sound with SS serving as a pre, however it does seem somewhat brighter than the tube- tube set ups I have heard. The interesting part is I prefer that brighter sound with the blending smoothness - to each their own...

Perhaps it's a sacrilege to say on the tubes forum, but I do not believe that vacuum tube circuits are inherently superior to silicon. They are pretty cool though. A good tube amp sounds great, and the glow of the filaments is enchanting. The blue glow off my 2A3's pulses with the music, and it is like watching the dancing flames of a fire. And hey, if you get hit by a nuclear blast, your valve gear will still work after the EMF pulse. That's always a bonus.
