"Great RCA interconnects under $100?"

i second the ic-3, in my system they outperformed the signal analog 2 and silver resolution.

Excuse me, I have to do this... I can get an amp for $500, so why would anyone spend any more than that? Sorry, hahahaha.
Okay, now for disclosure. I make AweSound cables. I think mine are the best sounding of any of the Audiogon (not yet in a big store) cables. I sell a cable for $90 a meter, that is a gold plated silver. I know they can be whooped by $1000 a meter cable. But they are good, my Audiogon price for cables that beat the $1000 a meter retail is $149.
I say yes, you can! Okay, so other than my subjectivity, how about Audio Metallurgy, they can be had for under $100 new often, and under a meter very often under $80. (like a .75M).
The Monster retro Gold is about the only thing I've recommend from them.

Kimber PBJ - one of the most neutral cables I have ever used.

Marco; water and jeans are a commodity. HiFi audio equipment is not; apples and oranges. Of course one can get ICs for < $100. Just like anyone can buy a watch for < $100. The question is, if taken verbatim: do GREAT cables exist for <$100. No.

Pawlowski - I'd suggest you re-read my post, as I don't think you understood it. I was not trying to compare water or jeans to IC's. I was using those examples to illustrate that people will pay more money for a given item for reasons far more complex than whether or not the item is actually "Better" than a cheaper version of it. I was addressing your original question as to why people would pay more if what they were getting weren't "better" - They'd pay more for all kinds of reasons.

Taken verbatim or not, I disagree with your blanket statement. It is an entirely relative judgment call and will vary from individual to individual. A quick search of archived discussions on this subject will reveal there are those who claim to be able to hear a difference, as well as those who cannot. For those who cannot, I'd say that great cables exist for under $100. Taken further, to those with arguably "golden ears", just look at the speaker cable shootout in TAS where they threw in a Home-Depot extension cord in the mix with much more expensive cables and discovered that the sub $50 solution did many things better than far more expensive boutique cables. I stand by my original response; it's all subjective and you should use your own system, your own room, your own music, and your own two ears.
