Class A does often sound very good - I used Classe DR3 VHC which with 45 watts will drive low efficiency speakers like Apogee Scintillas, and Belles A.
I don't think you will find, nor need anything like the Class A power you are asking for to drive just about any speaker out there. You'd be amazed what amps that are well under 100 watts in true class A can do - but you may want to consider that they are running all the time, putting out anything not used in amplifying signal as heat. In one system I run a pair of DR3 VHCs and in summer it gets pretty darned hot in there.
Others made pure Class A amps of modest output - Electrocompaniet, Bedini, and they would drive the heck out of very difficult loads.
For $2k you should be able to pick up some A/B amps with sturdy power supplies that will give very good sound - if you were closer, I'd offer you a Rowland I have for sale!
