Silnote Audio cables & pricing??

I am thinking of trying a pair of the Silnote Morpheous
Ref II cables and am wondering what you think of them?
I want to try a pair between my integrated & DAC. Also a bit confused by the prices. On their site they all look like they are over $1k, but are all over the net for $150 +. Are they really a high dollar product with bad resell, or are the retail prices just super inflated? Really just wondering as I cannot get a handle on them and not sure if I should buy new or try to buy used. I know the obvious answer is to call them and see, but wanted to check here first.

Thanks for any info & thoughts.
