Hi All -

My left 8000 will jump about 3 or 4 db in output, from my listening position every day or so.

I'll recalibrate the speakers and using an spl meter, it's nearly 9 or 10 db louder at the cone then when initially calibrated, though my 861 displays the correct db attenuation.

After I go through the calibration again and store it, the 8000 returns to the correct volume again - for a day or so.

This doesn't seem to occur when the system is in use, but rather after it is on standby for a couple hours - meaning I don't notice any jumps in the midst of playback.

Also, this left 8000 is the master.

Does this sound like a comms issue, or something else? I do not have another m-lead to test this with. I was thinking of making the center channel the master, and using a different comms cable with this speaker in order to see if the behavior is duplicated with another speaker.

Anyone have any issues remotely similar to this?

Thanks,
Andrew
