I reconfigured my system.
Since acquiring the Spendor SP3/1R1's, the subwoofer I have was not really adding anything, so it has been stored away in the basement. I also decided to go with a 2 x 2 rack arrangement vs. the tall 5 x 1 rack configuration. This lowers the height of the rack behind the speakers, looks less overpowering in my small room, and allows me to set up a second turntable.
Speaking of which, the BIC 960 on the right will be replaced with one of the two 1958-59 Rek-O-Kut B-12-GH's that I am presently fixing up. It will be installed in a stacked plywood plinth, and probably mated with either a Grado Laboratory wood series arm or an ESL/Ortofon S-1000 arm.
