What do $2500 speaker cables sound like?

@ghdprentice 
You mentioned that your cables get out of the way. In my opinion, boutique cables do not get out of the way of the music. Quite the opposite actually. They're doing something to give the listener the illusion of more this or that or less this or that.
The wire inside your amplifier and inside your speakers is NOT your boutique speaker cable. Remember that.

Just my opinion.

@russ69  Inside amplifiers and speakers, is there $5,000 Kimber?  $10,000 Purist? $20,000 Nordost? Is there big, huge, anaconda thickness cabling woven in specific geometries with specific shielding and silver plated copper wrapped in Teflon etc, etc, etc?

When you add those cables between an amplifier and a speaker you are also adding a certain signature of sound. Those cables are not getting out of the way of the music. More specifically, they are not getting out of the way of your amplifier or speakers as if they weren't there.

Plus, I believe that whatever money one has spent on renting equipment from Cable Company, that money gets put in a "pot". If you decide to purchase something now or down the road, that pot money gets deducted from your purchase price.
