length of interconnects for passive preamp


I understand that when using a passive preamp short interconnects are recommended. I have two questions before I purchase them: Does that short length requirement apply to both the ic between the source and passive as well as the passive and the amp? And regarding the length itself, is the shortest always best? I see that some companies offer a 1 foot or even 6" length - which I could use, although it would require some serious rearranging of my equipment; but will those very short lengths provide a noticeable improvement over a 1.5 meter or 2 foot ic? Not sure if there is a rule of thumb. Many thanks!

I think it largely depends on if you're connectors are single ended (RCA), or balanced (XLR).  If you're running RCA IC, then you probably want to keep them at 1M or 2M.  For XLR, the length becomes more irrelevant.  

thank you - mine are RCA - and I can go very short place my passive in back of a amp - is there any sonic advantage to going less than 1/2 meter?

@majorc - In my rack, the minimum length of interconnect I could use due to shelf spacing is 1/2 meter (20"). So i use a 24" Custom cable for some added "wiggle room".

For a passive stage - I would want to use the very best cable possible to maximize signal transfer.

I highly recommend Zavfino cables like these two

  1. A cable that employs UP-OCC copper
  2. or their silver cable

Take a look at their website - they have great products

Hope that helps - Steve
