Creek responded to my request by confirming that it's a tarnish issue on the ribbon connector pins joining the pre-amp to the volume control PCB and power amplifier PCB. They suggested connecting/dis-connecting these connections several times to wipe the contact surfaces clean. I did this and followed up with a thin coating of Pro Gold on the pins before buttoning it all up.
First off, the repair worked superbly.
Secondly, the system sounded better than I had ever heard it before. I can think of several possible reasons for this but rather than try to analyze the "Why" of it, I'm simply basking in the wonderful outcome of this interesting odyssey. I listened to it for about 12 hours today and simply marvel at the improvement.
Thank you again to all of you who shared your thoughts with me on this question.
