I would only suggest doing three lines 2 analog and one digital..You will be pissed later if you decide to add another component and don't have the extra line..Its not much more bother and expense,so do it now or be sorry later.......
Use cable which is UL-approved or your fire insurance will likely be voided. Chris Ven Haus of VH Audio sells cryo-treated 12 gauge Romex cable for just this purpose. I would think that would be worth using. After all, your Porter Port (good choice!) is cryoed.
Do get at least two lines pulled while you're at it. If three, as Thorman suggests, is too many, well, you can always isolate your digital gear with an iso transformer later on. Make sure the electrician runs the lines independently all the way back to the breaker box--no shared neutral buss.
Use 12 gauge wire, not 14.
This is a good move, you will not regret it.
Go with 20 amp circuits. 12 Ga. is now recommended for residential circuits and that is adequate for 20 amps. Once you go with 12 ga. the cost difference is the circuit breaker cost difference which is trivial. If your code allows, use PVC conduit.
If you go with two or three lines make sure that all are on the same leg from the breaker box otherwise you may run into ground loop problems.
I'll see your three and raise to four (been living in 'Vegas too long...).
Personally, I'd install four lines:
2 for mono blocks
The above is all good information. I agree run at least 3 dedicated AC lines. Eventually Im sure you will want three.
Hire only licensed contractors, get a permit and have the work inspected. Put in more that you think you need. Contractors love coming back for more of your money.
Thanks a lot guys. Very helpful and I feel much better moving forward now.
Just did it last month with 4 lines and a separate subpanel with Romex wires and Furutech ports.
I live 4 blocks from powerlines (not sure good or bad) and berfore installation, the room had pseudo dedicated lines except for lightings
Improvement was not jaw dropping at any single aspect but there is noticeable improvement on almost all aspect. Before installation, I had to run preamps, phono off a conditioner; otherwire there is lost of subtle detail, soundstaging and texture. After the dedicated AC installation, the difference with and without AC conditioner is insignificant.
Why do folks suggest 2 dedicated lines 1 for analog and 1 for digital? Why not one? Using a power strip for added outlets from the dedicated line to plug all your gear into.
Digital adds noise to the AC line.
My dedicated lines are being run as I type this. Thanks for all the advice. My electrician is running the lines on the same leg and not sharing a neutral bus, which I don't know if he would've done had it not been for your advice. I ended up running two lines (12/2 Romex) one of which I'll plug in my amp and pre, and my DAC and transport will go in the other. I know I should've probably run more, but this seemed like a good start and since a power conditioner or surge protector is in my future this may end up being enough.
So now I have my old line, one dedicated line with a Porter port and one dedicated line with an average recepticle (I'll upgrade that to a Porter port at some point). This should make for some interesting comparisons and I'll report back on the differences in case anyone might be interested.
Sure, Soix, if you got the time to report back, I'd be happy to read your impressions.
I originally ran 2 dedicated 20 amp lines. 1 for digital and 1 for analogue. I was impressed. I have since added 3 dedicated 30 amp lines, now having a seperate line for each component in my rig. I am completely floored by the improvement!
The result however is that each component now seems to be very sensitive to changes in Power Cables and AC outlets. AC outlets I am running a mix of PS Audio, FIM,Cryo'd Hubbell and ATL Newcablestudio. The ATL's are the sweetest of the lot.
All components share a single ground which has prevented Ground Loops and so far has not transferred noise component to component.
Dedicated lines have been great for me, however they do shine a bright light onto the weaknesses of the components which depending upon ones point of view may be a caveat.
Isn't Audio fun!!
"My electrician is running the lines on the same leg and not sharing a neutral bus"
While my electrician will follow this, I'm not clear on it. I had thought all main breaker boxes have a single neutral bus i.e. there is no choice. Or am I missing something very fundamental (which could easily be the case! My understanding of this is limited).
Initially my "dedicated" line shared its neutral side with other circuitry on the same floor. The electrician had run a single wire from the breaker box upstairs down to the ground floor and connected the neutrals of several ground floor circuits into that. He did this because it was easier to fish one wire than several, and the space behind the wallboard was already cramped. I had him do my dedicated line over again, properly dedicated on both sides this time.
