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?
