Need advice ono a Tube preamp


I have never tried tubes.I am currently running B+W matrix 801s seriesIII.I have several bryston amps a few 3b ssts,4b sst and 3 bst.I also just purchased a sony scd-1 and a moon eclipse.
I wanted to try a tube preamp in this system.I have never tried one and I know little or nothing about them.OK,I know nothing about them is more like it...lol...
I don't want to sacrifice bass response,channel seperation etc but want to warm up the highs abit.Is this possible with a tube preamp or Should I try something else?

thanks for the advice,much appreciated.Are tthere any tube preamps I should avoid?You can just email me with this response as I don't want to affect someone's livelyhood.Thanks again.
If I buy a tube preamp new then:
1) how long does it take to burn in
2) how often do you need to change tubes
3)will changing the type of tubes affect the sound much/little and if so are there certain tubes that are considered to be better than others?
Sorry for all the questions but I have really no idea about this stuff and am trying to lern before I buy.
Thanks for all the input.
I see some tube preamps have one tube,some 2 and some 4.I only need a line stage preamp.I would also prefer balanced outputs.As I am trying to warm up the mids and highs a bit is it better to have more tubes? Or does the number of tubes even matter?
