Dietech Platinum interconnect

Is anyone familiar with Dietech's Platinum interconnects? I have a pair bought about 9 years ago, (demos). They are bi-wire in purple jackets, with black mesh cover. I think they are silver cables?
Any info would be appreciated.
I had heard they are no longer in business. I listened to them several years ago and felt they were pretty good for that time period. The newer interconnects on the market would easily outperform them.
