Anyone compared Premium AC wire to regular romex?


I am curious. Am getting ready to build a dedicated room, with dedicated AC Lines and was wondering if there really is a SOUND difference in the premium AC wire (Virtual Dynamics, JPS, etc.) compared to regular good ole' Romex??

Does the extra cost really go beyond just having the overall benefit of dedicated AC lines?

Regarding the use of "custom" in-wall or ac wiring, isn't it more important to have a wire that is as neutral sounding as possible? Why would you want your in-wall wiring to add an effect which may or may not really be positive. Perhaps a person might like this upgrade in some situations but perhaps not in others.

I would say that as long as the dedicated wire is shielded and has the ability to deliver good current as per your components needs, the improvement yielded should be enough for that type of upgrade.

If I am to color the sound, I'd rather have more control of it downstream. I could be wrong though.

I'd like to see what others may write about this too.
Denf; 12 awg THHN is just regular 12 gauge stranded copper wire. Each outlet required a hot, neutral, and ground of the THHN wire. It's used for running in conduit. The electrical company supplied it and it's pretty cheap-- any electrical supply store should have it. As my sub-main breaker box is on an outside wall, the THHN wires had to be put in plastic conduit against the outside wall of my listening room.

If your listening room is 50 ft. from your main breaker panel, you might consider having a sub-main breaker panel put in (as I did), and then run dedicated wires from the sub-main to each outlet. The downside of this is that the sub-main panel and conduit on the outside of the house is sort of ugly. Fortunately mine is in the backyard.

Avnut brings up a good point, ie you don't want a "colored wire". However, it's been my (limited) experience that any wire has it's own sonic signature, ie I found 12/3 Romex between main and sub-main to be sort of soft and uninvolving, whereas the big Zaner 6/3 stranded was much more live and dynamic when run the correct direction-- but it was also a little bright.

Lak (in the archives) compared 4 different "house" wires including regular Romex and Virtual Dynamics 10/4 cryo, and was not able to hear a difference among them, and I respect his experience. In my case, I think the old Zaner 6/3 was just inherently bright, and replacing it w/ the VD 10/4 (very live, natural, and relaxed, but IMO neutral)corrected a problem in my ded. AC system. Let us know how your ded. AC system works out. Cheers. Craig
I should have added that I think the dedicated AC system for your stereo gear is much more important than the type of wire used. I suspect that dedicated 12/3 Romex would be fine, and a huge improvement over plugging your stereo gear into the general house AC system.
Is it possible to add another, seperate breaker box, say 20 feet away from the main panel, on the same inside wall as the main breaker??
Yes, you would just need an available space for a standard double wide breaker in your main breaker box. I used a 30 amp Square D breaker in my main breaker panel from VD that had been cryo'ed. I can run 4-5 outlets from this 30 amp breaker.

If you can do it this way, you would avoid the need for any exterior rated wires, panels, etc. I'm assuming you could then run ded. lines in the wall from the sub-main to your individual outlets. Craig
