comparison of different dedicated AC line types?


Im getting ready to move my audio system to another part of the house. I'm wondering if anyone has had any experience in comparing a regular dedicated 12 Ga romex line feed to a greenfield (flexible metal conduit) dedicated 12 Ga feed line? Also has anyone tried to terminate a dedicated line with an IEC and plug it in direct to your equipment?

Speaking from experience with a friend who went through numerous steps upgrading his dedicated AC line, solid core is better than stranded. Improvement achieved going to !0ga replacing 12ga, and additional improvement going to 10ga Cryo'd Romex from VH Audio (no affiliation) replacing the standard 10ga Romex. Also, better to have at least 2 lines, one for analog, and one for digital. He was not using a very high power amp, but a high quality 60 watt pure class A.
I think I will run two different ones to see if I notice any difference in my setup, then go from there.

I run a dedicated 20 amp line into a Hydra two for my digital gear.Another 20 amp dedicated line directly into a Guardian 2 for my analog gear.No problems just use good quality connector.

The advantage of separating the digital from the analog is worth the extra effort.
Electrician I hired was told to get romex...is that what he installed...no...typical (orange)10 guage line from home depot.Same stuff was his reply...

by the way cool article and thanks for that jea.

Hugh improvement though...easily worth the money spent
