What do $2500 speaker cables sound like?

" Malman, it’s not surprising that you are in the zip cord camp, IF your system is setup for listening as it is pictured in your system profile! "

One of the more amusing things to me with people that stop in from the Klipsch forum who followed the Super MWM build thread there is the expression on their faces when they first hear these while they watch the hair stand straight up on their arms at times. My goal was very high fidelity, great efficiency and to sit right next to the 32’ organ pipes or the Cellos or anything else, which it does quite well. It is like that sleeper daily driver hot rod that just waxed your $350,000 supercar. It may not look real pretty but it is all business. If you are near southern middle Tennessee you are welcome to PM me and stop in for a listen and see for yourself.

1+++++ for Silversmith Fidelium!!!
$1200 for an 8’ pair. $175 for bi wire adaptor.
I replaced $6K great cables that are now junk.
 Read that others have replaced $20-$30K cables in $600K and $1 million systems. Fideliums smoke all.
They were the biggest improvement in my system ever!
30 day return policy. I am only surprised that I am only the third to rave about them in this thread. 

To me its all sooo convuluded.

It seems an understanding of how the signal is lessened as it progresses thru a cable.

therefore, to minmize this, it requires great design to overcome complex tech challenges, and this costs money, otherwise we could all use telephone wire. 
So please focus on how the signal is impacted if not treated better via more costly cabling.

@jumia,
Reading your comments it difficult to ascertain how interested you are in exploring your inquiry. As several posters have wisely suggested, you can essentially "rent" /audition cables of interest via the cable company. They are very good at accommodating this type of scenario.

Select several cables that interest you and patiently listen to them intently in your own system. Trust your ears and just listen and compare in a very familiar home audio system. How do they compared with your current speaker cables. Buy some zip cord wire and judge how it matches up with the more expensive audition cables.

I believe that you will find some cables are clearly better than others (Like any category of audio products). Most expensive is not necessarily always the best but ’generally’ speaking you’ll get what you pay for. I believe that the higher quality the audio system (Resolution and transparency) the easier it will be to hear differences amongst the various cables.

This method is the most direct and effective way to satisfy  genuine curiosity.

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.
