Not at all. And I'll keep an eye out on AudiogoN for sure.
Anything in particular to look for?
Well I'd avoid any cable that has a rising upper octave eg. many silver cables (IMHO). Next, I'd look for cable with good bass foundation and speed. Then something that really gives you good retrieval of space (something the Maggies do unlike almost any speaker) and dimensionality. I can't speak to the sound of the lesser priced cables from these co's but I'd give a listen to MIT/Transparent/Nordost/Cable Research Labs/Kubala-Sosna (not sure on the entry cable prices but if price is a factor, just try to keep lengths to a minimum). In addition, another inexpensive cable worth checking out is Twister Pair Designs. Reviewed them many, many moons ago in Ultimate Audio and it's a good honest performer. Art Almstead also design the cables for Cable Research Labs and Krell's Cast cables.
