Yamaha MX-1000U, CX-1000U, EQ 1000U. All with remote control units. This amp and preamp are incredible STILL. I don't use the EQ much with exception with some of the redbook cd's. In perfect condition.
Yamaha CR 1020. Wonderful unit. Some recent problems with the volume control. Hoping to find a way to fix that.
McIntosh XR-7 loudspeakers (4) with the model #107 Mac equalizer. Also a pair of XR-5s. JBL L65s. All in pristine condition. The Macs blow the JBLs away but I use them in different systems.
I also own a vintage auto as a seasonal car but that's another topic.
Vintage can be fun if one chooses wisely and takes care of it.
