XLR vs. RCA

Yes you would/should benefit by running balanced interconnects over a length that long; reduces noise & RFI pickup.

Bob is correct in stating that balanced cable runs tend to offer reduced noise. That being said, I am running over 11 meters of single ended RCA interconnect between my preamp and amps. My system not only sounds extremely good, it has absolutely no noise problem.

TCiborow, the posts above are dead on. One thing strikes me though: Do you speak of running balanced or just using XLR connectors on your cables, which are used in a single ended fashon. If that would be the case, you would of course not have the benefit of reduced noise, if that (vide Albert's post) should be a problem at all. However, I find the Neutrix XLR's generally much better than the RCA plugs. Though difficult to clean, they give a fetter fit and cannot be unplugged incidentally. Some people maintain, that they also sound better with sweeter highs and less harshness. I'v never heard that myself, but then I did not specifically try. Curious about other opinions.....Regards,
