Tube reliability in amps


I am contemplating the purchase of a tube power amp. I already have an Audible Illusions pre-amp, which has given me virtually no problems tube wise. I would like to hear from a bunch of Audiogoners on how long power amp tubes last in the real world, do I have to keep matched pairs or sets around or can I just replace one? Also I have B&W matrix 804's and I have been told tube amps are not a match for them or that I need a lot of power (read expensive tube amp). Wavering between tube and SS, HELP.

PS. I listen to orchestral music and piano. Sometimes loud like about 90 db.

Thanks

I've had very good luck with Conrad-Johson, first MV-75A1s and now Premier l2s. The output tubes are biased individually (and easily). And, IMO, the sound is outstandingly musical. have to confess, though, that the fact CJ is about l2 miles away is very comforting.
