What do $2500 speaker cables sound like?

Life is way too short. If you aren’t taking food out of someone’s mouth to enjoy your hobby,have at it!  If some folks decide on others behalf how they should, or shouldn’t spend someone else’s money, step back and think about that for a minute....   If I read correctly,the OP was asking what could be expected in $2500 speaker cables.  Not ,please be my financial advisor.  Besides,last I checked,my wife’s name is on our checking account,not anyone on these forums. 

     

How do expensive cables sound compared to cheap ones?
I own 2 pairs of speakers.  With one pair, my Blue Jeans 10 gauge sounds absolutely fine.  With the other pair, they sound horrible compared to my Purist cables. The Purist cables sound great on both speakers, but if I only owned the one pair of speakers, I would have completely different opinions on the price/performance issue. 

Halve your budget, buy some Silversmith Fidelium SCs, and find out.

Op, Do you really want to know?  A $2,500 dollar cable will sound like a $25 cable, or a $100 cable, or a $99 cable, or a $20,000 cable or a $49 cable, or a $199 cable if you let your ears decide. If you let your eyes decide I expect a much more linear as opposed to random relationship.

Look at the system pages of most of the people advocating cables. What percentage of them have really well implemented acoustics? Aren't these people the self claimed cream of the audiophile crop?

Everything variable that matters in a cable for how we are using it can be implemented and controlled inexpensively. 

Do you have a limited even if extensive budget? This is not where you are going to make a difference.

Your best bet is finding loaner cables or purchasing with a no hassle return policy.

Otherwise it's a yes,no and maybe Merry go round.
