The ultimate subpanel would have it’s own line run from outside and its own ground. But that wouldn’t be Kosher.
What with all the dedicated circuit threads and with what I have been recently doing with my own, I was thinking that the ultimate & best would be to have a separate service (meter, panel, etc.) put in for just the listening room. This will not happen for me in this life time.
@emergingsoul , up until quite recently I was running three dedicated circuits for my system (which is currently four pieces). I had read a couple of threads here on A’Gon suggesting that one circuit was actually a better way to achieve the desired sonic result, so about a week ago I put everything on one duplex and turned the other two breakers off. (All three are on the same leg; that leg has one other breaker on it from a previous set of dedicated lines I ran, and it is currently unused and off; that leg also has the washing machine on it, which is never in use when I listen.)
I was not predisposed to thinking one would sound better than the other, although I was hoping I would like the sound of three lines better, seeing as how I had recently added three more dedicated lines. To begin with, I did not hear much, if any, difference (that is the way my ears/hearing works and why I hate doing A/B comparisons); however I felt that with only one line vocals sounded a tad softer and rounder and there was a bit more sparkle to the existing sparkle (and I am not using ’sparkle’ in a derogatory way). But after more sessions, I truly believe I am finding my listening experiences to be more enjoyable now. As an example, last night I put on the MFSL SACD "Pearl" (Janis Joplin) which has never done much at all for me. Besides "Me & Bobby McGee" there isn’t much that has really grabbed me, and I always thought of it as a rather flat & wooden sounding recording, and if my oldest sister hadn’t bought the LP when it came out, I probably wouldn’t own the two digital remasters of it that I do own. Last night it was blowing me away with the amount of detail I was picking up within a sound stage that I had never heard being that big before.
Anyway, I digress and I am sorry for the "Pearl" side story I went off on, as there could be other factors that contributed to that revelation. And back to the 1 vs multiple dedicated lines, it must be noted that the was I routed my latest three lines was not to the specifications that Jea has previously listed. I can remedy that, but for now, it is feeling like a project I don’t quite have the energy for yet. Therefore, I am (for now) sticking to just one of my three lines.
Oh well . . . ramble on. . . .
