Vintage monster receivers are a whole different audio experience and would not be my choice for a system aimed at accurate sound reproduction. I have several (Kenwood KR 9600, (2) Marantz 2325, Sansui G9000, and Pioneer SX-1050) and enjoy listening to them with vintage speakers and turntables of the day as an alternative to my hi-end rig when I get in the mood for vintage rock and even blues. I would buy the excellent SX-1250 with that type of system in mind and add Pioneer’s SG-9500 analog EQ.
Hopefully experienced and grounded owners of GoldenEar speakers can provide a better direction for you with your existing system.
