The poster below got the story only half right. The reason to use 1.5 meters is related to reflections, but it is specifically the timing of the reflections (not the distance per se). So a 2-meter cable is as bad as a 1-meter cable in terms of timing.

A 1.5-meter cable puts the arrival of the reflection from the receive end in the "fat" part of the pulse being sent (assuming a 44.1 kHz sampling frequency). What you want to avoid is reflections coming from the receive end arriving as the transmitted waveform is crossing the zero axis.

Markertek is a TV and satellite broadcast supply house (amazing catalog) that does lots of audio, but admittedly mostly broadcast audio rather than recording audio. They have one of the largest custom cable shops in the US, if not the largest.

Give them a jingle and ask them to custom-make for you a 1.5-meter Canare SPDIF cable with 75 Ohm terminations. It should not cost a lot more than $40. They are very reasonable.

Then, if you like it better than your (I assume) 1-meter cable, ask them to make an identical one for you and send it out for cryogenic processing, and then see which you prefer.

In terms of commercial cables, I would add Kimber and Audio Analysis to your shortlist.

Best of luck,

JM
