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.

Hey Seadogs, I am in Des Moines. I should stop in too. What electronics were they using?

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!

Consider the Focal 826W or 836W. Your current gear appears to be a good match. Since these are both resolving and forgiving speakers you can enjoy with your current gear. If you decide to upgrade your electronics you will be well rewarded. The decision between the 826W/836W would depend on room size and the ability of the Vincent to control 3 bass drivers on the 836W.

Vapor Audio Cirrus may be one to look into but the build times can be up to 9 months. There are members here that have waited at least 8 months to get a pair and there are others currently waiting up to 9 months right now. They do look like a very nice speaker however with very good reviews. I have been waiting to hear from these members to see if they are worth the long wait times since they have been dissapointed in all the delays. A really good speaker can make you forget about any delays in build times though.
