Recommendation for Digital Coax

Also I meant to ask is it true that it should be either less than a foot or more than 6 feet?

Thanks for the responses.

@chrisr  From everything I've been reading it has it's own drawbacks. Not sure why exactly but I've always been told coax. What you say makes sense especially if a much shorter length is a better fit but you are the first to mention it so.....

Maybe @auxinput can let us know?

A big thanks to @ghdprentice  and  ​​​​@auxinput. Your explanations make sense. I did some reading last night but there is so much conflicting info on the net. One sight had me nearly convinced the opposite was true. Thank you as well @soix . I followed your recommendation and your link. They are on the way. I dislike having to get a six-foot length as Medusa behind the gear can get unruly. I know shorter is available but why take a chance with the concerns expressed by @auxinput.

Thanks all for the responses.

@soix sorry for the delayed response; I escaped Michigan snow for Florida sand for a couple of weeks. I like it but of course I don't have any experience hearing other cables so I can't say if it's great or not. Arrows?

@soix you know, I.ve had this cable a couple of months now and though I was aware of directional cables I was looking at the terminal ends of the Apogee for that info and didn't see any. I just figured that mfg didn't buy into it so it didn't matter. After your post I looked this morning and found I've had it backward all along. I made the switch but haven't had a chance to listen to the difference. Thanks!!!
