$10k Speaker Cables??????????????

If the outlets improve power line issues, then no, you’re not crickets. 

I believe in high quality cables but not buying into the $10K+ price point some companies are marketing.  Some people obviously have too much money and too little brains.

I am not so sure. If you own $170,000 speakers. or $250,000 speakers.. Spending $20,000 on sets of biwires might make sense.

It is a fallacy to believe that buying ultra expensive speakers warrants ultra-expensive cables.  Besides the difference between $10,000 and $200,000 speakers is likely only on the order of 5% in sound quality (law of diminishing returns).  That would suggest that the very subtle "improvements" that ultra-expensive cables could (maybe) provide ultra-expensive speakers would be barely audible.

However, if you freeze those new cables, put wood blocks under them , attach batteries, put voo-doo goop on the terminals and ensure the the direction is correct...well then the differences could be mind-blowingly jaw-dropping!
