Digital cable optimal length?

Thanks Tobias, Almarg. I did search under 'length' and found more results. I quite don't understand the technical rationale other than maintaining certain impedance, I do believe that it would be unwise for me to buy longer cable to just try out, chances are it would be a waste of money.

I am not sure buying a 'cheap' 1.5 m and 3m digital cable form Radioshack would give me some conclusive result or not. But if does not cost too much, I might try this.

Theaudiotweak's answer 1.42 m is rather curious. Could you care to explain, Tom?

Yes, Indeed Al. Thanks for elaborate clarification. It is much more clear now.
Thanks Roadmann99999 for the link. I had Canare once. $32 for 3 m digital cable is a surely a bargain. May be for me the solution would be to bring my other transport closer to my common DAC.

I am still itching to try out though. If it works, it will save me a lot of trouble. The real estate between two transports, a Pre, three TTs, two phonos is really crowded. All of my components have separate power supplies too, and that makes things even more jumbled.

The Canare idea sounds real good. I will report back. Later..

Excellent info Al. Now it is much clear as to what is happening. So then, is it possible to precisely calculate optimum( high success rate) length for 44.1/16 bit data transmittal? I am getting greedy here. Is 4 m better than 3 m. I am sure I won't need longer than 4 m. Is AES/EBU automatically better either at 3m or 4m or SPDIF exceeds AEU/EBU for this lengths?

Thanks,

Nil
