Unplugging / replugging Anti Cables Changes things

If you've changed ANYTHING else, I'd look there first... If you haven't changed anything else, two possibilities exist: 1) You're imagining the change in sound, or 2) The performance of one of the components in your audio chain is deteriorating.

In the case of #1, I simply suggest that you imagine it sounds like it used to; and for #2 (that will be more difficult to track down), but if you use any tube gear maybe a tube or tubes are showing signs of aging/deterioration.

I highly doubt that what you described is the result of plugging and unplugging cables... Normally, a system sounds better after cables are unplugged and then plugged back in (at least in my experience).

Funny one Plato. My audio imagination is not that great when something so obvious is happening.

Knownothing: I will try separating the Anti Cables speaker wire further away from other cables. The power cord is perpendicularly running (90 degree) running across the Anti Cables.

I used anticables in the past. I disconnected them and re-connected them and they never sounded the same again. I only moved them slightly when I disconnected them from the back of the speakers and amp. They never returned to their previous performance even after a substantial time to allow them to settle back in. I never could figure it out. I checked phasing, spade connections etc. You may have to buy another set, but that experience turned me off. One guy suggested to me that I had stressed the connection of the spades to the cable and that could be the problem. There may be something to this since the connection is not the sturdiest.

Foster_9: I am glad that you seemed to experience the same thing as I do. I have just moved my power cord further away from the unshield Anti Cables speaker wire and if they are close (at least 2 inches), they are perpendicularly (90 degree) running.

I will need more extended listening time to deduce whether this will get back to my previous performance of the broken-in (never unplugged) cable.

Could some one here let me know how far the Anti Cables Speaker and interconnects should be separated from other shielded cables including power cords to avoid RFI.

I foundnd anti-cables sounds congested when i reversed the cable direction after burn-in .
Much worst if only one channel reversed.
