Pure Note Designers Edition

There is not much information about this cables. How do they compare to other "big". I'm tempted to buy them but would like to know more. Are they full bodied, rich? Are they dark or bright , how they convey, differentiate tonal colors.
I don't like lean, bleached and edgy sound. The review of Epsilons in Positivefeedback sounds bad to me.
Not much valuable info about this cables in the review on Audiogon either. The reviewer owned Synergistic Research cables but doesn't write much how they do compare. What they do better and in what areas they lack.

I purchased the Designers Edition interconnect. Excellent cable indeed. It replaced AZ Absolute in my system. Smooth, transparent, detailed, excellent sound-stage. I liked treble of DE better and it was a bit more quiet. AZ Absolute had slightly more authoritative bass but it was a close call.
