Audphile1 - The retailer said 150-200 hours so in the same range as you. Thanks.
Zlone - I've noticed that used cables take a few days to settle in as well. Amazing that it would be this sensitive but here we are. Thanks.
Mark 200 I saw that some are cryoing cables too to speed break in too. I'll wait for a cold winter day and put them outside for a few hours. LOL
Audphile1 and Jay - do you know why it would or wouldn't need to be on? I guess this is a technical question that's above my pay grade. Thanks!
