Pure Note Designers Edition

The TSR Audio is not offering these excellent cables any more. Have they stoped production of Designers Editon? Is the new production as good as the DE?
I believe you mean TRS Audio. The cables are no longer, replaced by their TRS brand (which is also excellent, IMO). According to Jim at TRS, their agreement with the defunct Pure Note company has ended and they are building their own products now.

The TRS brand is sonically very good and well built. Price is also fair for this quality. I have pair of the interconnects and they are on par with the DE's that I have owned for over a year. Just my .02.
