do you need to elevate interconnects?

I have elevated both interconnects and speaker cables. While I have found a definite improvement in sound, especially greater presence, with speaker cables, I've yet to discover any benefits by raising interconnects off the floor. Your experience may yield the same or different results. Explore on your own and see/hear what you get.

Incidentally, though I've had short and long (up to five meters)interconnects elevated off the carpet without audible improvements, I've never heard any "injury" to the sound while running them along baseboards, and I've never run them under a carpet.

Opus88, thanks for your response, very helpful. I wonder why more people don't avoid the whole elevating the speaker cable issue by going with longer interconnect runs and shorter speaker cables. While there is a lot of debate about whether longer speaker cable or longer interconnects are better, it would seem -- if indeed your experience is generally the case (no problems having interconnects on the floor) -- that this would be a big factor in favor of going the longer interconnect route.
