Does a tube preamp warm up sound of SS amp?


I'm thinking of getting a SS amp for my Mag 3.6's to get the power I think I need. Would a tube preamp sweeten and warm the sound? I'm leaning toward a Bryston B4 SST2 amp (but nothing definite yet). Any ideas for a tube preamp that might work with it? Are there any conflicts that I should look for with a tube preamp and a SS amp? Eg, impedance issues, etc? Thanks so much for your help. Laurence

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.
