I received KnuConcept 10AWG cable and Sewell banana plugs from Amazon today. I've been using 16AWG cable from Walmart and dinky plugs I borrowed from my buddy thinking "It's no biggie. It's just an 8 foot run to each speaker." I have 12AWG in my walls that I use for surrounds and my old v2 but since the 1500 came in, I've been using the 16 gauge.

Dummy me! After a listen with the old cables, I switched to the new ones and kapow! Instantly improved bass and clarity throughout the entire range.

After some measurements and calculations, I figure I was losing 50 peak Watts on each old cable. The old cable was dropping almost 3.5 Volts.

Given this large improvement, I'm gonna get me some 0000 cable. laugh

A larger ADA would also help with the M5s. No problem with the M100s though.
