I re-read your question and I don't think that I saw anything about the type of music you play or what kind of sound you might be looking for.
That sort of makes recommendations rather tough.
That said, I agree with those that recommend PRO gear. Meaning not the "B" word or its ilk.
British Audio Service has a smoking V300H amp for sale (NOS) for $450. That leaves you $750 for a nice bin (or bins). Go visit the current "Trace Elliot" thread on this forum if you want to know a little bit about what many consider to be one of the greatest lines of amps ever made. I think this is an extremely fine deal. For that kind of money you could get cheap Chinese stuff. Why bother?
As far a speaker boxes: Schroeder, Bag End, Genz Benz, Mesa, EA, Eden, bla bla bla bla bla. . .
On the other hand, if you just want to blast as loud as possible (and many do), any old mainstream brand will be just fine. No offense to anyone playing lite jazz through an SVT. Sorry.
