New Dedicated Line - Almost No improvement

I suggest you spend another several million and put up your own mini nuclear reactor for YOUR house.  That way, you can run a single line for EACH outlet--if you still use outlets...I would connect DIRECTLY to the reactor, myself, but that's just me--and that way you will have NO NOISE and be sitting center front at every mix-down studio where your recordings are "created" from whatever the musicians play that day from wherever they are playing.

Oh, spend another million or so on patch cords.  They really matter as well.

Cheers!

Well, yes these not true dedicated line in the sense of providing your own independent ac line, even a line run from pole wouldn't be truly dedicated as sharing with everyone else on that trunk line.

@richopp takes this thing to extreme, funny! But yeah, we'd have to go to extremes to eliminate all noise on ac lines. Some, I included,  have tried batteries for provision of audio power, but even this has limitations in the sense of noisy inverters.

@sns Thanks for understanding humor when you see it.  Today, many have NO sense of humor at all.  I guess I feel sorry for them...

Look, other than attending a live show, ANY system is going to be different from that show, and, given the new "digital" age, one wonders why people complained about compression in the old days when today, every bit can be manipulated in the mix-down studio.

I totally get why people seek the last bit of perfection from their systems, and noise is probably an issue in some places.  Methinks one should enjoy the music and buy the best stuff that works IN YOUR ROOM.

We sold lots of Audio Research/Magnepan systems in the day.  Still have not heard anything that is better, but to each his own.  This is why we carried and sold 50 different lines of products.

Cheers!

I have 2 dedicated 20 amp 14ga copper lines to my audio equipment.  Transparent Audio power conditioning, Furutech duplex outlets in our new home. A giant difference to me.

My electrical contractor also paid attention to the number of motors on the circuit and box and don't underestimate the value a good ground. BIG FACTOR.

Those are my experiences FWIW

don’t underestimate the value a good ground. BIG FACTOR.

Can you elaborate on the grounding in your system? Was the electrician experienced with installing dedicated lines for an audio system?
