As my system has improved, I was forced to recognize that my dedicated 10/3 runs sounded worse than a shared, daisy chained 12/3 run. My advice to all, do it right the first time and buy something like Hidden Treasure or at least get cryo'ed romex from vhaudio, even then I would probably recommend 12/3 if possible. The 10ga sounded better in terms of dynamics and low bass, but the 12ga sounded much better in the mids thru the treble. You could build a couple DIY power cables with 12/3 and 10/3 and listen for yourself before you have the work done. I wish I had.
