replacing Dunlavy SC-IV's

As someone who liked Dunlavy speakers, you should give serious consideration to the Vandersteen Model 5A, which shares a number of performance characteristics with the now-defunct Dunlavy line. The Vandy Model 5A sells for $15k, while the original Model 5 is about $3500 less.

I have owned the IV,IV-A, and the V's. Another audiogoner"Calloway" turned me on to the piega line. I now own the c-10ltd which are better in most ways than the Dunlavy's. The bass on the Dunlavy's is bigger if your room allows you to get it right which I could never do. With the right associated components the piega's will provide excellent music.

If you like Dunlavy, besides the obvious bigger Dunlavy', you might want to consider Green Mountain, Meadowlark, Vandersteen and especially Thiel.

My prior system was a full Cello system driving the B&W 800's. Nice sound.
I was on a mission to improve on that sound so I was looking at the Dunlavy VI's in contrast to the 800's. Well, during my quest for better sound I came across the Avantgarde Duo's.
As I listen to World Music with a lot of female vocals, percussion, drums, etc. there is a certain sound I seek out - the Duo's do it!
I would like to suggest that you audition the Duos before making any decisions.
Yes, a major departure from the Dunlavy sound, but what an improvement to my ear.
Recently a close friend and I went to a friends home who has the VI armed with a collection of my reference CD's to again confirm or disprove my earlier impressions - the Duo's won hands down!
