Dedicated Circuit

@millercarbon  I'm only planning to run one dedicated line.  Don't need anything more than that.  I recently got some power cables from Ice Age Audio on the recommendation of Don Sachs.  A good power conditioner is on my list of future upgrades.  Currently using using a basic Furman unit. 

@yogiboy Thanks for the link. I was actually looking at that exact wire on HD's website a few hours ago.  

In theory, the running of a dedicated line to your stereo should help to eliminate "noise" created by other appliances sharing the line.  TV would be a good example.  Keeping in mind that both power conditioners and your amplifier are supposed to be able to clean up the power source, filter out all the noise and eliminate ground loops, it's questionable how much a dedicated line adds to the overall sound?  If you choose a 20 amp breaker, your local building code likely mandates a 12 gauge wire.  Depending on your system, even this may be overkill.  During operation, your average stereo probably pulls less than 2 amps.  The standard 15 amp breaker on 14 gauge wire should never be a problem.  Having said that, if your taking the time and trouble to run a dedicated line, I would go 12 gauge/20 amp.  10 gauge wire is quite costly and not required.  

Do a forum search for posts by jea48. His comments provide the most thorough and professional advice regarding dedicated circuits, including answers about what specific wire to use.

Thanks for the info!! Since I don't need to tear up any walls to run the wire, my thoughts were might as well run a dedicated line.  It certainly won't be detrimental.  Also, just found my dad has 100 ft of 12 gauge Romex at his house.  My only expense would be getting a higher quality outlet.
