FYI. I had been using a 10 gauge extension cord for my amp from my dedicated line into which my power conditioner was plugged with all my other equipment. My amp is between my speakers the rest off to the side by the direct line. I got a hum if I plugged the amp into the outlet behind it (goes to a different breaker box). I was having some other electrical work done, so I had an additional direct line (10 gauge) run to my amp from the adjacent breaker.
Happily it did what I hoped for: no hum and better sound. It further dropped the noice floor, revealing more detail. I wasn’t really expecting it to sound better, but it does. At $1,500, about the cost of a power cord with the associated improvement, a worthwhile investment.
I will review different cords again.
