How to guarantee to lower noise- ground loops in your system

I have been through many problem area where noise in the  audio chain was a problem.
my friend Who is a Electrician solved the problem . All too many times people add a dedicated 20 amp circuit 12awg is standard 11-10awg even better lower resistance , also most important 
you need a Isolated dedicated ground, this is totally insulated right back to the earth ground in the 
breaker box this will dramatically lower your noise floor and remove ground loop problems .many people just put a dedicated line and think 
that’s it ,not so, if you are going to go through the trouble, then  for maybe $100 more the isolated dedicated ground  to the dedicated circuit is a must. I can tell you without question .
my Audio has a noticably quieter background .in songs i now hear low level musical artifacts like reverb off a guitar fading cymbals and clearer seperation of instruments .well worth the effort .Hopefully 
this will help others .this is a essential system upgrade .

Eliminating ground loops has more to do with product design than electrical wiring, the latter of which should simply be to code.
Actually its neither.  Bottom line is ONE reference - regardless of what that is too (virtual earth, actual dirt, etc.).  Product design can give some tools, but anyone can thwart a designed by connecting several products together (RCAs carry signal ground) and grounding them to subtly different points - e.g.: different outlets.
A dedicated line is good but has nothing to do with loops per se (you cant have a loop with one wire!).  A dedicated ground is good, but you can;t have two (the one the electrician made and the one you run).
Bottom line: back to what i said - everything grounded to one, single potential, in a "shortest path star" config.
And burn incense. :-)
