In what laboratory or think-tank...

It is actually been proven in double blind testing that this length of digital cable is lab tested and proven BS!

Somewhere in the Agon archives Audioengr provided the math to show why this length "could" be superior to shorter lengths. It primarily has to do with vswr / signal reflections / jitter. Sean

Sean...And its a proven fact that bumblebees can't fly.

I was browsing over at the Empirical Audio web site and, unfortunately, could not find the tech paper about this issue. I did notice that they sell 3 different lengths of digital cables (.5, 1.0 and 2.0 meter).

Respected cable manufacturer, Chris VenHaus, quotes the following on his website: "Optimum length for digital (SPDIF) Interconnects is >1.5 meter!"

Is this length issue only in regards to RCA and not to AES/EBU termination of the coax?

Thanks all for your imput on this topic. I am debating changing from the 1.0 length I have now but, as usual, am a bit skeptic. I use the AZ Mc2 AES/EBU model at present.

It was found that the probability wave collapsed for propogation of electrons in lengths longer or shorter than 1.500000000000000000000000000000000000 meters.
