I realize that we all have our opinions and preferences. So, I am just adding my present arrangement to the discussion.

After many years of trial and error and upgrading 50+ years:

1. I ran 3 10 gauge runs to my breaker box. At the end of these runs, I have 2 each Furutech NCF outlets.
2. One dedicated line is reserved for my Video, one for my subs (4) and one for my Main system.
3. On the Main system I have a AQ Niagara 7000 plugged into the wall with a AQ Dragon power cord.
4. Into the AQ 7000 I have my 2 (Large) 1500 wpc mono blocks plugged into the Hi-Current outlets connected via Dragon power cords.

I have tried the amps directly into the wall and I prefer them plugged into the HI-Current outs on the AudioQuest Niagara 7000.
