Digital Coax Cable - Does the Length Make a Difference


Someone (I don't remember who) recently posted something here stating:
"Always get 2 meter length digital cables because I have experienced reflection
problems on short cables, resulting in smeared sound and loss of resolution."

With all due respect to the member that posted this, I'm not trying to start a
controversy, just wondering if others have experienced this.  

I will be looking for a Digital Coax cable soon to run from my Node2i to a Dac.
I really only need 1/2 meter. Not sure if a short cable like this is a problem or 
just a case of Audio Nervosa.

I have recently heard definite differences between a 1 meter and 2 meter digital S/PDIF.  This includes even a true BNC to BNC cable with proper BNC connection on source and DAC.  Using a Nordost Heimdall 2 cable, there was a loss of high frequency response and detail with the shorter 1 meter cable.  The 2 meter cable solved this problem as well as some other "not quite right" things with the shorter 1 meter cable.
Any optical cable that is lower cost (under $50-60) is going to be made from monofilament plastic.  While these are okay, they do also have a loss of high frequency resolution.  If you use optical, you really want a glass fiber cable.  These are definitely more expensive.  The best for the money is always going to be Lifatec ($120 / 3 feet,  or any custom length).   There are other more expensive otions (Wire World Supernova 7, DH Labs Glass Master Toslink, etc.).
