I wont be using a 590 unless I get too weak to carry the 100 pound amps around (Which could be any day now). My current inventory is:
Dag 400 Monos, ARCĀ 160M Monos, ARC REF 10, Audio Note Jinro, Ayre KX-R Twenty,Ā Pass Labs XA-25, Luxman C900/M900...and some older Multi Channel amp/pre combos (Arc/Conrad Johnson)
