This might seem excessive to some but I have four McIntosh based systems. I know, I lost control a long time ago.
My main system consists of a C1000C/P preamp, a pair of MC2301 power amps, a MR88 tuner, an Esoteric K-03 SACD/CD/DAC, an Olive 04HD music server, a Sonos Connect with digital output through a Wyred 4 Sound Remedy to the K-03, a Michell Gyro SE turntable with the Never Connected PSU, an SME 309 tonearm w/Ortofon Cadenza Black moving coil cartridge, a PS Audio Dectet, a PurePower 2000 AC regenerator, Sonus faber Amati Anniversario speakers, all connected with Wireworld Silver Electra power cords, Silver Eclipse interconnects, Silver Starlight digital coax, Super Nova fiber optic, Platinum USB and Silver Eclipse speaker cables. The gear is isolated on a combination of Symposium Rollerblock Jr's, and Stillpoint Mini's, the turntable is isolated on a solid maple Boos Block supported on Symposium Fat Padz. The room is fully treated with ATS acoustic panels and bass traps, and Vicoustic Wavewood panels.
