Anyone ever experiment w/ better circuit breakers?

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,

Glen, I'm keenly interested in the comparison b/ween p-conditioner in & out of circuit.
Good point about the b/ward comparisons!

Yep - ceramic fuses are best downunder too!
