Anyone ever experiment w/ better circuit breakers?

Bob is right as far as my ears are concerned. I threw all circuit breakers out and installed ceramic fuses. Much better punch and dynamics. Cheers,

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.
