Dedicated line help

Finally getting the dedicated line I've always wanted, but had a few questions on how it should be done for best results. My electrician is kinda young and is not an audiophile (the flipside is he's only charging 75 bucks to do it), so I'm relying on you guys for the details.

Some general info in case it's helpful: The system is in the basement and in the same room as the circuit box about 30 feet away. The wire will be fished behind the walls that fortunately have a few access panels between the box and my system, and there is no insulation between the wall and the foundation -- just some heat pipes (steam heat).


Is 20amp strongly preferable over 15amp line or does it not matter that much? I'm currently running a 125wpc push/pull solid state amp but may very well run something like a 100wpc class A ss amp in the future, if this makes a difference.

I'm going to purchase a Porter Port, but is there certain type/brand of wire that should be used from the circuit box to the Port or will the standard stuff do fine?

Should I have him run 2 lines -- one for analog and one for digital, or is there another way to separate these guys (or is it sufficient just to do this at the power conditioner, which I don't have yet)?

Anything this guy could do wrong that could cause problems or create a fire hazard?

Any other tips you guys have either on the installation or equipment would be most appreciated. THANKS FOR ANY THOUGHTS/HELP.

Go ahead and run 20A circuit, it's basically the same cost.  I keep my noisy stuff on a separate power conditioner than my analog.  I also use ifi Wall wart adapters wherever possible and use shielded power cables and interconnects.

It doesn't sound like you'll have much of a power draw so 1 circuit would be sufficient.  When listeners have a lot more power, and are far from the main panel a sub-panel may be a better option. 

One other possible option is to run a 20A/220V line, and use a balanced power transformer in the room to step it down and give you balanced power.  Lots of watts available then for the least amount of copper.

Just my funny way of expressing my ignorance of the term as I never heard it before and could not find its purpose on line.

A few things I've learned, but I'm by far not the most knowledgeable in this area.

- Run dedicated lines, 20 amp circuits, oversizing the ROM-X wire to 10 gauge helps. 

- There debate to use aluminum armored cables as a shielding, not sure of the results.

- Run all the power lines from the same phase of the circuit breaker box (note: breakers alternate phases in vertical sequence.)

- Do not run the wires close together, leave at least 6" space between each wire run.

Anyone else can help with details?

You do realize this is a very old thread.  I think this was back when the OP had a Lafayette receiver and a BSR turntable.
