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 have N804s and am about to go tube as well. From this and the Audio Asylum forum, I have found that at least my N804s will be alright with 100wpc tube amps for loud hard rock, and around 50wpc for jazz and vocals at good volume levels. Two reasonably priced tube amps float my boat at this time. The Cary V12 which can do 100wpc ultra linear and 50wpc triod at the flip of some switches ($4000 retail new) The other is the VAC PA 100/100 which does 100wpc. I have seen the VAC used here for $1800-2500 and the Cary used at $2500. There are other choices. My Cary SLP 2002 pre will arive this week . Present amp is a BelCanto EVo 200.2.
