Dedicated Line - Things to consider

All…thank you so much! Lots of good points on the dedicated line as well as on the surge protector.

And @immatthewj thanks for posting those links!

@bikeboy52 thanks for the compliments!

@ghdprentice I’m keeping this one simple - no audiophile wires :) just good quality copper is all I think I will need. 
 

I’m leaning towards 2 lines. That will allow me to connect monoblocks if I ever go that route, and keep the source separated from the amp(s). Will figure it out in the next month or so. Putting it all together into my plans for early 2023.

@audphile1    I agree two lines.  I have three lines - one for each Krell KRS200 and one for all the rest.  Make sure the new lines come directly off your supply board before supplies for the rest of the house.

I have never heard RF noise on this system.

Check your main earth and consider improving it, advised by knowledgeable contractor.

What I’ve done making 2 outlets suppling 4 high output sockets on 4 breakers. Needed 10/3 wire, 2 hospital grade outlets, 4x  20 amp breakers. Cut/break the gold bar joining the 2 gold screws on both outlets only. From one of the 10/3 wires put red wire (hot) on one gold screw and black wire (hot) on other gold screw, again make sure gold bar joining both gold screws is separated. Put white wire (neutral) on either of the silver screws. Again do Not cut/break the bar joining the two silver screws. Attach green ground wire. Do the same with the other 10/3 wire and remaining outlet. Next go to your panel install 4x 20 amp. breakers, install one black wire (hot) to one breaker, one red wire (hot) to another breaker. Do the same to the remaining two breakers with the red and black wires from the second 10/3 wire. Attach both green ground wires to ground bus bar. Now put both white (neutral) wires to (neutral) bus bar. You now have 4 sockets on two outlets with 4 independent 20 amp. breakers, safe high power to play with.

I don’t know this to be an audio-fact, I am only surmising, but I suspect that it is possible that the effects of RF might not always be a detectable/audible hum or buzz. I think it might also produce a grain that you wouldn’t even realize you were hearing until you were NOT hearing it or a lack of blackness to the background that you didn’t realize that you didn’t have until you DID have it and etc.

But with that typed, I am STILL using all three of my dedicated circuits to run my  four pieces of audio gear. I have a few things that are higher on my list at the moment, but I am definitely intending on experimenting by running my gear off only one of those three circuits and turning the other two breakers to ’off.’

I agree! You don't realize how much hashing noise is on the AC lines, until it's gone. 😎
