Wow, $10k+ cables

Attacking others asking questions does nothing to support the case for any particular wire expensive or otherwise. Fact is it hurts it if anything.  If one thinks a particular product is worth it just state the case.  Avoid generalizations.   The merits of one product has nothing to do with another at any price. 

The OP is on to something here....

I would use $9,999.99 cables on my "Statement" grade boxes.
More bang for your buck than the $10K offerings.

I would think the 10K+ power cords will sound fantastic in a system  that is worth $300,000 or more. 

I am afraid that would not be enough to get the very best. More like $15k.
