Best I2s cable for the Money?

I have the I2S cable that came with my Offramp Turbo and one from Revation Audio Labs. There is a difference between the two but I'm not sure if one is better than the other. I also tried a 2 meter ethernet cable (same thing as an I2S cable) and found I liked it better. I'm not sure why that would be.

I would settle for a nuetral cable; anyone know of any caparrison testing results?

BTW: I am buying a Pacecar from Empericalto connect to a Sonos via I2s. A cable is included, though a Silver upgrade can be had for $360.00. So I guess I'm asking where the point of dimishing return starts on I2s cabless.

If it were me knowing what I know today I'd stick with the stock cable. IIRC the RAL cable cost me $295 and versus the stock Northstar cable I didn't hear that much difference. I have no comparative test results to refer you too, but you might want to try over on Audio Asylum. There could be some valuable information over there.

I just bought a used Audio Alchemy DDE1.1 and DTi 1.0. They have I2S connections that I would like to try out. Does anyone have a old cable that they can part with? Perhaps someone that has a stock cable and have upgraded?
