Anyone ever experiment w/ better circuit breakers?

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!

I ran three dedicated circuits up to my bedroom yesterday. Same as before, three hots, three dedicated neutrals, one isolated ground and a dirty ground. I used Hubbell industrial grade I.G. receptacles.

I plugged the amp into the first one, pre-amp the second (Recommended by the factory) and power conditioner the third. I then plugged the transport and Dac into the power conditioner.

What did I here from this tweak? Nothing! AND A LOT OF IT!! The noise floor had dropped dramatically. I barely heard any hiss coming out of my speakers. Even when I pressed my ear to them and cranked the volume up full blast they were unbelievably quiet. (With nothing playing of course).

The music leapt off a pitch-black background, much darker than before. The instruments had more separation in the sound stage and I could actually hear the wood resonating off some of them. AMAZING! I must say I am a believer in dedicated power now. Even the wife noticed a change.

I'm actually afraid to touch or tweak the system any more for fear of losing this newfound magic. To think I had given up on my Thiel 3.6 speakers many times in the past never once realizing they could sound like this. I can’t imagine the sound being any better even from speakers costing twice as much. GREAT SYNERGY :^)
