Based on my own listening experiences, Sean's comments are accurate. I would add a couple of points: the Dunlavy's are both time- and phase-accurate, which the JM Labs are not, which may partially account for their different "sound" which Sean describes as "dry". The Dunlavy's may be better suited to combined audio/home theater use than the JM Labs, and infact are the speakers of choice with several home theater reviewers (see Widescreen Review mag for a listing of their equipment).
Some audio reviewers have criticized the large Dunlavy models for having a distinct "large enclosure" quality that draws attention to itself, rather than "disappearing" as some speakers seem to do. The same reviewers have also noted that the Dunlavy SC-IV model seems to have a less-pronounced "box" sound than their large models. Of the two speakers under discussion, the JM Labs speakers seem -- to my ear -- to call attention to themselves less than the large Dunlavy's.
I am not as emphatic as Sean about either loving or hating the JM Labs family sound (the same might be said about the Dunlavy "family" of speakers), although I agree there is a clear family resemblance among the middle and upper-priced models. I personally find the JM Labs models I have heard to be somewhat euphonic, which is also characteristic of other French-made audio electronics I've experienced (sort of the opposite side of the coin from a lot of German-made audio gear).
Given the amount of money you are planning to spend for either of these speakers, I really think you should find a way to audition both of them at some length. These speakers sound sufficiently different from each other that you may like one but not the other, and it's a lot of money to spend without some demo sessions.
I have a couple of questions in return for you, and the answers may be relevant to the speaker you ultimately select:
1. what are the dimensions of your listening room (all of these speakers are large)?
2. will you be using your Classe amps to drive the speakers?
3. will the speakers be used solely for music reproduction, or will they also do double duty for home theater? (I note that you have a surround pre/pro and multi-channel amp in your system.)
