Mark - I wish you the best as you battle your health issues.
Just a quick note others may be interested in. I picked up an 1800 from AXPONA and have 2 JC1's and my Exogal DAC and Mac Mini plugged into it. After letting it settle for a couple of days, I feel it has made a nice improvement over the Running Springs I had been using. There seems to be a little more uumph on the bottom end and the mids and highs have more separation between notes. The soundstage has moved further away from the speakers and into space, which is great. Overall, everything just seems a little more musical than before - And I am using the $99 cord, not an upgrade. Highly recommended.
Mark, if you need someone to test a Deep Core, you let me know :)
