Length- Speaker wire/interconnect ?s

All of the above are good replies. Do keep in mind that in either case...speaker wire or interconnect..the shorter the better. Define what the total is between your source(s), your pre-amp, your power amp and your speakers,.. then come up with the total lengths and divide as you see fit...although the suggestions for the longer length being the interconnects is accurate. The thing to remember is that ALL wire...shielded or not...is an antenna for RF and all other airborne electronic noise. Would any audiophile open up any component they have and lengthen any of the internal wire?,..of course not. This is why that no matter where it is, or what type it is (digital, interconnect or speaker) the shorter the better...waveguide logic does not apply.

Actually RF and EMI can and do have impact on audio components. Human hearing may be limited to 20k...but your pre-amp, power amp, and the audio sections of cd players, tape decks, etc. are not as limited as human hearing..and if RF is introduced in any part of the audio chain..components can be affected as they either expend efforts to amplify/pass along these higher freq's...or worse intermodulate them with the audio signal. So, the problem with RF is not a wire problem..it is a system wide problem that wires can add to...and while it is true that humans cannot hear RF...and other airborne noise....RF can interfere, in very negative ways, with the audio range that we can hear. All of the powerline devices, internal shielding in components, power supply filtering, wire shielding...etc. is based on this..it has never been that we can hear RF, it is simply that RF, in the audio amplification and wiring chain, can and does cause problems for the frequency range we can hear.
