Belden? what kind of cheap monoblocks do you have to use that crappy cable?
Nice gear shaming @urbie - however solid gold cable also seem to obey the laws of physics.
Spoke too soon about no hum. It got really quiet in the house tonight and had a good listening session and left the earlier comment where I said "No hum. No noise." When I stopped playing music and stood up, I heard a slight hum. I got closer to the speakers and they just have a monotone hum coming out of them. Going to need to troubleshoot the hum this week and figure out the cause. Lots of things going on that are different -- also switched from low level subwoofer connection (interconnect) to high level coming off the speaker binding posts, so not sure if it's the 15' interconnect or the high level subwoofer connect that is causing the hum. Maybe the hum is making the soundstage better. ;-)
This is great.
Great to find this out now.
Is it easy to run an extension cord to the mono block?
That “test” could allow us to determine if the monos are on a different circuit.
Or you can flip breakers to work it out.
Your trouble shooting plan sounds good.
