Any comments on Vh Audio Spectrum interconnects?

I'm thinking of upgrading to a $400-$500 interconnect, and was advised on AudioAsylum to try out the Vh Audio spectrum interconnects. Anyone know how they sound? Or can anyone recommend a good interconnect in the $400-$500 price range (new or used).

Thanks any and all.
What interconnects are you using now and what type of change or improvement were you hoping for? Where will it be in the chain, and what are the components in your system?
