Best speaker cable in the $2,500 range


I have been reading many reviews about the following speaker cables in the around $2,500 price range (for an 8 or 10 ft pair) but can't seem to come to a consensus as to which one would be the best choice. I am looking for a pair to upgrade from my Transparent Musicwave Supers. Any feedback on your experiences with these cables is much appreciated! Thanks!

Some to many (including a reviewer in Stereophile Aug, 03) claim the Audience Au24 speaker cables are superior to the Nordost Valhallas.

It's amazing what the Au24's have done to remove time-smear in the bass regions and to remove grain and hash at the higher frequencies.

I recently purchased the Au24 ic's and find them to provide similar benefits and far exceeded my previous ic's which some others also rated as being superior to the Valhallas.

And the Au24 are priced well below your $2500 range.

-IMO
You might want to add HMS Gran Finale cables to your list. The speaker and balanced IC's are particularly fine, and fall well within your price range.
I would put the Analysis Plus Solo Crystal Oval 8 up against any on your list above. And these are subtantially less than your $2500 limit!
