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 been very happy with CJ tube amps for reliabilty, sound, and ease of tube replacement and rebiasing. I'm running the CJ Premier 11a as it does a fine job with my Thiel CS 1.5's. I'm not familiar with your B&W's and if they are in fact "difficult to drive" then you might want more power and that usually equates to higher cost. (not talking about low power SET amps here as they do not apply in this situation).
