what is the best sounding speakers for under 5000.

Just today listened to the Pioneer S-2EX loudspeakers at Audio Video Logic in Iowa. For $4995 including stands these speakers IMHO are one of the BEST Value in loudspeakers today.
You owe it to yourself to give them a listen, they are wonderful.

Kclone, they had a Mac amp and I believe a Rotel CD player. In my opinion they would have sounded even better with different electronics but even as such you could hear the potential. Good Luck!
