Will tubes rock?


I have to get a new amp, my acurus A150 was destroyed in a recent move (don't ask). What survived of the move were my spicas, acurus ACD-11 and parasound pre.
I keep seeing great deals on tube amps, and wondered if as a class I should be auditioning these during my search. I've heard some Cary and VTL products in systems that sounded wonderful but were way out of my league. 70% of my collection is rock with less than stellar recording...the rest is jazz, folk, and orchestral. Any thoughts?

Given the room dimensions (though it's pretty square which can be a big problem) you could feasibly rock with a little 2A3 3 watt/channel amp if you paired it with efficient speakers. Most any linear (as neutral as you like it) push/pull amp would widen your speaker options. I have already experimented with different tubes (output and driver) in my 300B amp and can extend the frequency extremes, though with losing some midrange roundness, just by changing the 6922 tube.
