After 4-5 years of upgrading my hardware, piece-by-piece, to the horror of one of my audio buddies, I think I'm "done" with system upgrades for the foreseeable future. I've got hardware I really like, "dialed in" to the "man cave", now I'm teaching myself about classical music, which I've enjoyed, but don't have much experience with.
My system:
McIntosh MC452 power amp
McIntosh C50 preamp
Bryston BHA-1 headphone amp
Autonomic MMS-5A music server (coax output to the DAC)
PS Audio P10 power plant
PS Audio DirectStream DAC
PS Audio PerfectWave CD transport (I2S output to the DAC)
Dell Laptop running Tidal, iTunes & Roon (USB output to the DAC)
Focal Sopra No2 speakers
JL Audio F113V2 subwoofers (2 of them)
Sennheiser HD800 headphones
Wireworld cabling
