1.5m for 75ohm digital coax?


Hey everybody.

I am going to upgrade my RCA coax cable connection between my Monarchy DIP (re-clocker)and Musiland MD10 DAC. I'm upgrading from copper to silver.

I have read numerous posts on this and other forums that one should use at least a 1.5 meter length to prevent signal reflections(or something like that). Is this length really necessary? I only need a .5m cable and these silver cables are expensive.

Mike, you are talking about digital cable here. For digital cable, impedance is important but length is not, unless you are talking about very long length in which signal degradation becomes a factor. Signal reflection is caused by impedance mismatch, not length. You shouldn't have to spend more than $30 to $40 for a good digital cable, silver or copper makes no difference. Don't spend too much on it.
