Where do I make the long run IC or speaker cable?

I vote for short speaker cable, long interconnect.

As Tpsonic mentions though, you could check with a cable manufacturer, or even an preamp/amp manufacturer for that matter.

So far the count is 3 to 2
3 say short speaker wire
2 say short interconnect
Any one else like to share their experience?

I have three different sets of 10 meter ICs from pre to amp and 1.5 meter speaker cables. Speaker load is highly reactive as compared to the IC's load. So far, no dicernable problems with this arrangement. Especially if you're running balanced (as I am), I think long ICs are the slam dunk. For clarification, obvioulsy, I can employ only one of the three sets at any given time.

I have to ask how long is long? I've used both configurations with great results. What matters most is the cables used.

I received my information from conrad johnson as I run their electronics and they suggested short inteconnects.....short as possible........over speaker cables. With long interconnects I believe it is recommended to use a balanced design; not sure what the break point length might be. Conrad johnson designs their equipment with single ended (RCA's)only. I believe their manual states that interconnects are more susceptible to picking up interference than speaker cables. But I have not experimented with this only taken their advice.
