I have a PS Audio Power Plant Premier, a DIY parallel AC filter, RC filters inside my preamp and EQ, snubber caps on all tube heaters, ferrites on the heater and B+ lines, and my preamp uses DC for the signal tube heaters. Every single additional noise reduction step decreased background noise and improved the sound, and I started with the PPP as the first one! They are additive.
If you have a line conditioner, does noise matter?
I have Belkin, BPT and Brick line conditioners. I have a friend that says his electricity is "noisy" due to garbage on the ac lines and he claims that he can not listen during peak times and can only listen late at night.
My understanding of these various line conditioners is that they control spikes and brown outs to keep the volts at 120 +-. Shouldn't this take care of the ac "noise" on the lines allowing only the music to flow through unimpeded?
