Speaker cable survey - does cable matter????

[Barry]

Passive intermodulation can be caused at the junction of dissimilar metals or if there is an oxide layer involved, or if permeable (magnetic) materials are used. This phenomenon is well known in RF circles (often referred to as the "rusty bolt effect").

I was involved with the design of a harmonic radar system, where we had to suppress the self-generation of harmonics to a level of -134dBc. This meant we had to avoid Wilikinson power splitters (because of the nichrome bridging resistors used) and stainless steel connectors, amongst other things.

However at audio frequencies this phenomenon is highly unlikely to be audible. IMO, all one sensibly needs to use is cable having low loop resistance and inductance (such that the impedance at 10 - 20kHz is no more than 0.4 Ohm) with sensible tight fitting plugs or spade terminals that can be screwed down firmly.

Maybe a few metres of this would sort most systems out. Don't forget it's mono, so you'd need to double up. .

Oh, and factor in the cost of suitably good plugs.

These might do. http://www.ebay.co.uk/itm/Furutech-C...EAAOSwjXRXYBfN

can i have an inch please?

Years ago I had an Adcom 555 and back then, good OFC Monster cable was all there was, high end cable had not been "invented" yet. Anyway, I rung off the posts! So, I soldered the wire directly to the amp. Worked great! But didn't sound any different.

All I can really add to this thread is that I used to use Mark Grant VDC 4mm cables and I swapped to Van Den Hul Teatrack biwired stereo and in my system there very definitely was a difference to the sound and a difference that I was happy with.
