interconnect burn in via tuner?

comb filtering is the most plausible explanation for many of the differences people claim to hear from cables, power conditioners, isolation devices, low-jitter external clocks, polarity reversal, ultra-high sample rates, replacement power cords and fuses, and so forth. Comb filtering is a specific type of frequency response error that occurs when direct sound from the loudspeakers combines in the air with reflections off the walls, floor, ceiling, and other nearby objects. Ask yourself, do I sit in the same spot every time? The answer will not surprise us because it most likely is NO.Unless you strap yourself in your chair and its bolted to the floor we do not always sit in the same place.This just might be the reason for comb filtering, moving even a tiny distance changes the response by a very large amount at mid and high frequencies..

Break in is real. Why ? Not important. My Morrow Audio MA3s took a long time to break in, but way before the "60" day trial period. In fact, in my experiences, to my ears, everything has had a break in period (when new) and have benefited from it. Thank you.

I can't see how just leaving the tuner on but not have the amp running will break in the cable. It will not be performing any function will it?

George (Xti16) is correct, Stan. The input of the amp will "look" essentially the same to the cable and to the tuner whether the amp is on or off. The amp's input impedance, and therefore the amount of current that is drawn through the cable from the tuner, will usually be determined to a close approximation by a resistor (perhaps 47K ohms for a typical unbalanced input) that is connected between the amp's input terminal and ground.

Disclaimer: No opinion about the value of break-in is expressed or implied in this response :-)
