Dunlavey SC4 vs B&W NAUTILUS-801(original)

Looking to opinions on these speakers. I currently run the SC4's in my system with a Mcintosh
 2500(rebuilt) and a mac mini(modified) as a front end. System sounds great and I mostly listen to R&B/Neo soul and just starting to venture into jazz.

Those that own or have owned the 801 nautilus please provide some feed back as to your experience with these speakers and your impressions of them.
