Anyone ever experiment w/ better circuit breakers?

Would someone like to set some percentages on this tweak? After (a) dedicated circuits, (b) hospital grade wall outlets and high quality in-wall cable, (c) a/c line filters, and (d) audiophile grade power cords everywhere (not to mention the Quietline shunt filters in every unused outlet), am I REALLY going to be able to hear what changing the circuit breakers does??

Flex, you pose a tough question. When I was persuaded by my technician to change to ceramic fuses on all my lines, I pretty much had all the tweaks you mention already installed. I did the change more for puristic reasons, but being basically doubtful. But having done so, I had the distinct impression that the music came through with better dynamics. I cannot give you a percentage, it happened a few years back and the ear adapts so quickly to positive changes, which hence seem normal immediatedly. Of course I cannot be sure, if this is once more a case of autosuggestion, but then, if I had to start from scratch, I'd do it again. Cheers,

Whatever you do, do not use ground fault breakers which are extremely noisy.

I installed three dedicated circuits a couple weeks ago for my H/T system. I used dedicated neutrals, isolated grounding and a dirty ground. Everything was run in conduit. Nothing-fancy just #12 THHN. I have upgraded all my power cords and have a line conditioner. I too use short out plugs on all unused inputs. I can say I like these upgrades and know they are all good for my systems but realistically I did not here much change in the sound quality.

Sometimes you don't here something after you add it, but notice it once it is taken back out of the system. I never realized I had boomy bass till one day I tweaked a tube pre-amp into my system and WALA! It was gone. That's when I realized I had boomy bass before.

This weekend I am running three more dedicated circuits to my bedroom system. Being an Electrician by trade this is a relatively cheep tweak for me. I may do away with the power conditioners down the road. I'll let you know after I have had ample time to test and compare.

Very good point Glen! Often enough you only fully apprehend the effects of a tweak, when you have taken it out of the system again, just as you said! Cheers,
