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?

Sogood51 - you missed the point entirely. You should read the WHOLE white-paper:

http://www.positive-feedback.com/Issue14/spdif.htm

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.

Ha good one! I think that is a sarcastic post?, the less cable the less feet the better.. But I never know on these boards with some of these jokers :)

I did read your white-paper on the subject a good while back...I try to retain so much in such a cramped space between my ears but I mostly forget 90% of what I read, (not because I want to).

I do remember that it was a very good paper...thanks for the link (and the other info), I will re-read the entire paper.

Steve, if the cable length is not the optimal "sweet spot" length for a given CD-transport, what is exactly the sonic effect? Does one hear a grittier sound with less air? What is what some experts mean when they say the sound is getting less (with regard to this matter). Can one always hear this sound degradation? Btw, a 0.5 m cable length difference is not very significant for interconnect cable in my opinion. It is therefore difficult to believe that it could make any difference at all.
