1.0 or 1.5 m digital interconnect, does it matter?


Hi folks, in theory 1.5 m length for S/PDIF should be better than shorter lengths. But in real live does it matter much if the cable length is 1.5 m instead of 1.0 m? I mean, does one hear clear sonic differences between the two lengths? Does one for example hear a grittier sound with the 1.0 m compared to the 1.5 m cable?

Pawlowski6132 is right, just get a cable that will reach from the input to the output and stop stressing. There is absolutely NO sonic difference between them, anybody claiming there is has to be a serious whack job.

No difference in my trials... I have had 2 meter vs. 1 meter etc... as well.. Only thing I can say is TOO short like the .5 meter might sound different, I did not do a direct test of the same cable in a .5 vs. something longer but the .5's I tried I did not like as much for whatever reason.
The .5 meter will sound better 1 meter if you use 3 isolation cones under your source instead of 4.
Sogood51 - you missed the point entirely. You should read the WHOLE white-paper:

There are "sweet-spots" in length for S/PDIF because of the way transports are made. I sell 1m cables to customers that have my modded Transports. This enables them to use the shorter cable. Extremely short, such as 9 inches is also a "sweet-spot". Stock Transports can sound better with the 1.5m cable, depending on the cable and the Transport. Most of them do, but there are exceptions. If the cable is not 75 ohms or is very lossy, then it may sound the same in all lengths....

Rlwainwright - serious whack job eh? It just so happens that an independent Audio magazine in Canada did a series of double-blind tests and published the results in their mag based on the claims in my white-paper. The results matched my conclusions.

The editor of this magazine came into my suite at CES last year and gave me a copy of this article. It was his hope to debunk my article, but instead he became a believer. This is pure engineering analysis, not snake oil. Read the paper.

And BTW, I have lots of inferior digital cables from other manufacturers than sound crappy in all lengths in all systems. Even in 1.5m, they dont deliver the magic. Proves nothing.
