Yes, it is all about Ohm's law, but there *are* some advantages to the "exotic" cables 1) they are usually made with large diameter wires, satisfying the Ohm's law requirement even with higher power amplifiers; and 2) they are quite flexible which makes running them in tight places easier, and they will stand more flexing before the wires break.
Other than for those advantages, any piece of wire of a suitable size for the max power involved will do the job - but I do use the lower priced "exotic" cables on my home theater system for the reasons stated. 73, Don W3FPR On 10/28/2010 4:43 PM, Jim Brown wrote: > On 10/28/2010 1:25 PM, Wes Stewart wrote: >> He swore that he could hear the difference between different kinds of >> speaker wire. > Bob Greiner, an EE prof long retired from Univ of Wis at Madison did > some excellent science debunking exotic wires 30 years ago, which he > published as an AES paper. > > *"Amplifier-Loudspeaker Interfacing", Greiner, R.A., JAES vol. 28, no. 5 > May 80 ** > * > The executive summary -- for virtually all real loudspeakers, it's all > Ohm's law, and nothing else matters.
