I second the Cary SLI-80. It's a flexible amp in that you can use KT88's, 6550's, El34's, etc., plus is has triode and ultralinear modes that you can shift on the fly. Plus is has subwoofer outs that many amps are missing and it has a great headphone out as well. Used Sli-80's show up regularly in the classifieds within your budget. Although I have not had the good fortune to hear the Jadis Orchestra, I'm sure its a great choice as well. IMHO, few integrateds exude class like Jadis and I hope to own one one day.
