Agreed ... I have been using a couple pairs in my system to wonderful effect. My long-time references have been the Stealth Indras (and I have not tried the new Synergistics Tesla series.)
For me, (and a couple others with whom I have spoken) they seem to be an ideal mate to another pair of Indras already in one's system.
They were not quite as "shockingly naked" as one person has described the Indras, but they really seem to be best described by Stewart's description on his site:
"We have tried many cables over the years, some proved to be very fast and transparent, some holographic, and some very lush and seductive. Yet over the years all of them fell short from giving the overwhelming presentation that embodied all of the desired attributes stated above. If you seek a cable that is organically natural sounding, that enchants with a rich delicacy and finesse, without sacrificing speed and transparency while enveloping you in a seductive blanket of warmth - this is the cable for you."
It sounds like more cable hype, but at least in my experience, it is right on the money.
Like others here, I would highly recommend contacting Stewart - he is a good guy and one of the true "cable gurus" out there ... always at the cutting performance edge with new products that to him, offer both performance and value (yes, even with a higher price sticker.)
