Several Racks that I rotate around, one all SAE, preamp, parametric EQ, CD, tuner, active crossover, speaker selector, and a pair of 2400L, set up to for bi-amping.
Another Rack of all Phase Linear series II, Preamp, Tuner, Parametric EQ, Spectrum Anyalizer, Time Delay, Noise Reduction and Range expander, and three amps, one 300 series II, a 400 series II, and a 700 series II.
A couple of other racks with assorted equipment from Crown, Mcintosh, Sansui, SAE, Rane, DBX, Soundcraftsman, Infinity electronic controllers for the RS-1, and RS-1b's, Denon TT, Tascam cd and cassette. Plan on in the future to refine these out and make them into one Mcintosh rack, and one either Conrad Johnson, or Audio Research rack, tubes for the mid-highs, and SS mono blocks for the base towers my RS-1, and RS-1b's.
