Find the amp whose sound you like, then contact the manufacturer to see which brand of tubes he recommends and which setting to bias at. Different brands in different amps perform differently. Also, the guys at the tube store (.com) have a lot of experience with this subject.
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.
