New Dedicated Line - Almost No improvement

@ditusa Great reference, much appreciated.

I ran 3 dedicated lines a few years ago. They are probably 12 g.  I haven't patched the drywall yet as I have had a lingering doubt I did it right.  My electrician did not have heavier wire and he struggled to pass the 12 gage in the walls.  I think I need to call him back out to replace add 2 more lines for each of my mono amps and maybe my tube pre amp.

I have found separating the digital and analog front end gear beneficial.  I have 2 mono amps on the 3rd line.

I use a PS power regenerator on the digital, a Shunyata Denali on the analog and the amps are plugged into a Furutech outlet.

I have been eyeing the PSM156, I was unaware of the trial.  Its hard to know what is snake oil and what works.  I tried an Akiko Corelli and it worked so well I bought 2 more.  I have one on each front end line and the third on the outlet in the PS Audio P10 that the music server uses.  My Linn LP12 has such a noisy power supply I had to take it off the dedicated lines and Shunyata conditioner.  The same for the SMPS for a pair of REF longbows.  The SMPS's totally polluted the PS Audio P10.  They are now polluting the non dedicated house lines.

I have a dozen PS Audio Noise Harvesters.  Those little things actually help.  I have them on the shared outlets in the conditioner and regenerator.

If you say you have a dedicated line and are getting noise from the AC then you dont have a true dedicated line.  A true dedicated has to be brought in independent from the street.  At the very least you are sharing a ground on your dedicated line.

@anzaanimalclinic, Your welcome!

I agree 100%! I have four dedicated lines, one for each monoblock amp, one for analog and one for digital. All four dedicated lines use BX/AC cable. I prefer the BX with metal boxes for better shielding. See reference below:

Maybe that BX wire is just keeping the EMI in and allowing it to transfer to the ground?

That’s true, but it has to meet code. It would be so nice to have an extra drop from the power company.
