Does a tube preamp warm up sound of SS amp?

I tried this with a BAT preamp and a B&K power amp. The more I thought about it, though, the more I realized you shouldn't need tubes in the preamp at all. The line level signals coming into the preamp need only be switched and attenuated. And you don't need tubes to do either of those things.
Anyway, I don't think the combination I had worked out very well and wound up replacing it with an Audio Research VSi60, which is the opposite configuration: tube power, solid state preamp.
I'm sure someone will correct me if I'm wrong. (Or even if I'm not.) But I would like to hear why tubes are a good idea in a preamp. It makes no sense to me. I'm not saying tube preamps sound bad, but that I see no reason they would be a good choice. I'm sure there are some that sound good, or, rather, don't meddle with the sound at all. But theoretically at least, there's no point.

In response to Ptmconsultings'comment I couldn't disagree more.Bryston amps and Magnepans have a natural synergy and a history of being paired by their respective manufacturers at audio shows and by dealers that feature both products.
Inclusion of a top tier pre amp in a Bryston/Magnepan combination will be the icing on your cake.

I think that is a popular config because the preamp tubes don't need biasing and the tubes last longer. I like leaving as much stuff on all the time (except in summer w/thunderstorms) so I would be more inclined to want to turn off a tube power amp, which should be turned off first anyway.
If I had a tube preamp I would turn off the power amp first, the tube preamp second. Not as practical if you want to have a transistor power amp on all the time.
