Spdif cable construction.

The last people I would take advice from is Audio Advisor. I can't believe those guys are still in business.

I cannot talk to all cables, but with the cables I use length makes no difference whatsoever.

I use KLE Innovations cables - which utilize a completely different cable architecture to the more conventional offerings out there and as a consequence do not suffer the same issues.

Regards...

HI Kev - I am at a loss to try and understand how re-clocking data in any way offsets the digital reflections that occur when the SPDIF cable is too short. It might be "Advisable" to talk audio with people that actually know audio.
