Tube in Preamp or Power amp?


I have been thinking to move from a solid state int. amp to the tube world. If I were to go separate and if one has to be SS, would it be better to have tube in the preamp or in the power amp? or would it make any difference since I'm mixing tube with ss?

Look what a good digital remastering does for a lot of old tv shows and movies. Why not expect similar results applying digital correction software intelligently to audio as well, if/when needed? God bless remastered CDs! Unless one likes to have various forms of dullness, fuzz and haze intrude on their listening. Why not use it to fix room acoustics, which are almost always sub-optimal otherwise, as well? Its on my list of things to try someday when time and expenses permit. It makes too much sense to just ignore. I know there are at last a handful of participants in these parts these days whose opinions I regard highly that swear by it.
Wenn Bo don't know, knowbody nose.
What Bo doesn't know is that he doesn't no.

With props to my friend wolf-e.
I have no beef with "room correction" per se, as long as it's not in MY system since I like the sound of my room...plus I have a "less is more" attitude with carefully applied (and carefully adjusted from time to time) REL sub levels, and prefer there be no extra cables, processors, language challenged self important Dutch Onkyo salesmen, nasty schoolgirls, or repo men between my preamp and amp. I can only assume the world is full of tawdry "sub-optimal" rooms begging for third party digital intervention!
Lyndorf there system fully eliminates the sound of a room. That's why it is useless. Hearing is believing. Audio is always about what we hear. ( and wanna hear :) People are always interested in a better sound than they have. Room acoustic system with tubes? Mmmmmmmmmm.........you never know! To be honnest when I sold Tact, I thought that roomacoustic systems never would be useful for highend. The same as that I never thought subwoofers would be fast enough for stealth integration. But technique is getting better, so things which looked impossible, are even possible these days. And after some time also for to none believers at this moment!!
"language challenged self important Dutch Onkyo salesmen"

Google search needs more improvement. Still not much on these guys to be found there.....
