I don't know what gear you currently use... But... The sound you seek can easily be had by placing a single run of Cardas Golden Cross between your existing preamp and amp.
Give that a try before you buy any amp - I think you will like the results and you'll save some dough.
If you still really, really want a new amplifier... Try something from Electrocompaniet. I know it's not on your list but...it should be.
