You mentioned the mini splits that PS Audio has in their listening rooms. Paul hates them and turns them off when giving demonstrations. We just added a room to our house and put in a highly recommended Mitsubishi heat pump. On its regular settings, it’s pretty quiet, but it’s still loud enough that I would still turn it off during a listening session. However, it does have a whisper mode and I can’t hear it when standing in the doorway.
Those magical days when the HVAC is off
I'm reminded these last few days when after 90 days straight with the AC running, the weather broke and the temps dropped, and with no AC running (or likewise in winter when no heat is cranking) my rig sounds easily 20% better - like I had added a new component- more clarity, overtones/timbre, sparkle - the standard sonic improvement adjectives - so how does one accomplish this year 'round? Which power related component is the one that allows your audio rig to operate unimpeded by air conditioning, the furnace, an overloaded electrical grid? I have separate dedicated lines to my components, but my rig really flows in a magical way when these climate conditioning appliances are not running. Is it power conditioning, or power regeneration that could possibly allow me to enjoy this increased audio performance more frequently or permanently? Any personal experiences of successfully solving this dilemma would be welcomed. Cheers, and thank you in advance.
