Interconnects Roller Coaster Ride

I purchased a pair of Morrow MA-1 interconnects, burned them in 24/7 for 500 hours. At present, I'm at about 550 hours. Each night I now listened to my system for about three hours. For two straight nights, the sound is gorgeous with the Morrows. Then the third night things sound bad. This pattern has repeated itself twice now. My assumption was that once the interconnects have been fully burned in, they will stabilize and will always sound good. Has anyone experienced this continued roller coster ride in good-to-poor sound from the Morrows?

I am very confident it's not the wires.

If the pattern repeats itself at regular listening intervals, most likely it is your ears picking up on something that is not right after a certain period of time. The new ICs may just be enabling this to a greater extent than prior.

More info on what sounds "bad" the third night would be helpful to facilitate some more useful feedback perhaps.

With tube gear, the tubes themselves (old? weak? not operating up to spec?) should always be an early suspect when something is not sounding right.

By wires, I mean the ICs that are/were the OPs prime suspect.

May or may not be power related and/or anything else at this point. I'd definitely try to rule out tube issues up front unless I knew for sure all tubes in play are working as they should.
