Wow, $10k+ cables

No one seems to complain about $10k amps. What makes anyone think that designing great cable is easier and less time consuming than designing great amp ? Production cost is less, I suppose, though something like silver/gold/palladium Echole cables probably costs a lot too. 

Fools easily part with their money. Cable believer and verifier, i draw the line at about $1000. 

I am assuming that I couldn't interest you in a matched pair of "ineffable" Sukhavati 3m, spade-to-spade speaker cables, of which the manufacturer assures "each aspect of sound presents itself as simply there",  at a mere $77,000.00 USD then? 

There are far less expensive PranaWire cables. $77k is too extravagant for any cables unless they are at a completely different level.

You can go to Jay's Audio Lab (White Camaro) on YouTube and compare his recent exotic power-cord swaps to listen for differences.  Out of my league, though.
