Darwin silver IC's or Cabledyne silver IC's?

The contact surface is all that matter's which is silver and copper. A very good quality connector.

TheXhadow has a outer and inner barrel. The outer barrel sleeve is aluminum. The inner barrel is solid copper plated with silver.

Not true Nonoise..the Xhadow connector sold by Cabledyne are solid copper plated with silver.

Reading the technical make up this morning on the Darwin and Cabledyne, shows their design's are very similar. The Darwin IC's use solid core circular wire running through an air tube. Cabledyne uses a solid core square wire running through an air tube called Hyflon MFA air tubing which seems to be more flexible and easier to bend then the stiffer Darwin which sticks out more based on the reviews. Cabledyne uses an outer sheath called Inconel Chromium alloy cable sheath which eliminates all electromagnetic interference. The Cabledyne's have superior connector's and cost less than the Darwwin's. Both companie's use Cryogenic silver. Is the Darwin worth the extra cost considering the quality of Cabledyne?

Absolutely..no pissing contest...just good healthy dialouge. It wouldn't surprise me at all that both Cabledyne and Darwin cables would sound identical. Both companies use .9999 solid silver wire that is Cryogenic treated, and both have their wire going through an air tube. Cabledyne has an additional non magnetic sheath over the tube and the Xhadow connector's they use made by Vampire have gotten excellent reviews and are expensive.
Cabledyne does have some very good engineers that are partner's in the company. Whats interesting is that Cabledyne is using a square wire they claim has better conductivity over the circular wire that Darwin uses. I think thats getting into snake oil territiory.
