I am about to acquire a pair of hand-me-down monoblock tube amps. I am entirely new to tube amps and don't know the first thing about how they will sound, but I am curious. The problem (?) is that they are just 8 watts each. What kind of speakers do I use for these? I have a pair of Klipsch RB5-II's and a pair of Axiom MT22's that are both suposed to be very efficient, but will the amps be enough? If not, what are some of my other options?
