HIGH Quality Electric Service Panel

I looked at balanced power; unfortunately it's just not in the budget.  

Agreed.  I know MSB well (I own the MSB Analog DAC, which is awesome!).  

Vince Galbo taught me the importance of the lower reistance theory  years ago and I rewired my old dedicated room with 6 AWG; it made a tremendous favorable difference.

In my new house, I am using 6 AWG for All my dedicated audio outlets (Furutech GTX-G) and each outlet will be on individual 20A circuts.  These all run to a dedicated service sub-panel in my room which is connected to the main panel by a 2 ought aluminum run.

Try it and then decide... it works!

yes, you have to junction box the 8 0r 6 down to 10 to fit the receptacle.  

I'm using the FuruTech GTX-D Gold.

You are correct; the greatest difference is heard when running these lines to AMPs, especially big wattage amps.   However, when I replaced my dedicated 12awg  line with the 6awg (in my previous room) for my 'front end' pre, phono, and DAC i got positive results; not as dramatic as with the dedicated amp life lines but still an improvement.
