Dedicated power circuits

So where do I find this twisted mc cable? All i see is untwisted or straight.

Thanks for all the responses. The Torus all in one looks interesting but at 18k it ain’t happening. Because of local code I’m going to have to use tamper resistant outlets which I will replace after the job is finished. Any special wire from the breaker box to the outlets? Any special breakers?

Thanks again for everyone’s help and advice. Joem2 what you did is what I’m planning. Did you you use any kind of special wire? I’m assuming you just used normal 20 amp breakers.

I saw that. I am having an electrician do all this work.

I really appreciate all the helpful suggestions. What I’ve decided to do is 3 dedicated 20 amp circuits using the 10 gauge aluminum mc cable and eventually some nice Hubbell outlets although for inspection purposes the outlets will have to be cheap tamper resistant ones. Thanks again for all the help.

So the electricians are here today putting in my 3 dedicated power lines. I had a new square D QO 200 amp panel box installed with all new breakers. They also installed a 26kw standby Generac generator along with a whole house surge protector. For my new lines I’m using 10 gauge aluminum clad mc wire and eventually Hubbell 5362 outlets. I realize I could have done more, and in the end I may go with some kind of power conditioner for my front end, but for now this is going to be it. Looking forward to a better and cleaner sound.

All the electrical work has been done and I have 3 new dedicated 20 amp circuits wired with mc 10 gauge wire and Hubbell 5362 outlets. The wire goes from the new outlets in my den, which is where I listen to music, directly to my new square d panel box with 20 amp arc breakers. I tried it out today and everything is working as it should. Today was just casual listening to my local NPR radio station, but I can report there were no hums or ground loops just very nice sound from my Mac MR 74 tuner. 

This week I should have some chances to listen a little more critically and will report how the sound of my stereo has changed. 
 

I had a chance to do a fair amount of listening yesterday and truly believe this was a worthwhile upgrade. I have my amp on one line my preamp on one line and my sources on the other line. The sound seems cleaner with blacker backgrounds. My system has never sounded better. By the way all three lines are on the same leg. I’m not going to write a flowery review describing how much my sound has changed but it is significant. Thanks for all the help guiding me through this process, it’s greatly appreciated.
