Dunlavy vs JM Lab


I'm thinking about taking the plunge and upgrading my speakers. I'm considering the SC V or VI versus maybe the Mezzo Utopia or Utopia. I'll have to buy used if I go the upper echilon. I'll have the opportunity to demo the DALs but not JMLs. Anyone out there with experience comparing the two please shed some insight. Thanks

Thanks for your attention and detailed explanations of the various points. To answer your question, it will be primarily be a two-channel system with some occasional double duty. I will be driving them with the Classe's. My room dimensions are currently 19' by 23'.

Gjames, a lot has been said about the Dunlavy and JM Labs. All I can add is that Dunlavy V'sare the most accurate speakers I have ever heard and been satisfied with them since last 5 years. Classe and Dunlavy make a good match with right cables. Due to the reasons mentioned above regarding time coherent feature, the dunlavy's have to be PRECISELY located and towed w.r.to the listening position. A 1/4 " or 5 degree difference can upset a balance. As big they are , they do disappear sound wise bar the visual aspect. I still get amazed at times at the accuracy of the sound at all freq spectrums. Sealed enclosures produce tight and accurate bass at the precise location in a sound stage. In fact the bass is so accurate and subtle that you don't even notice it untill you feel it (?). (Non precise placing effects the bass aspects the most) It does not draw attention it itself. The V's ( and I am sure VI's) do need ample power to shine ( CA-400 is what I use). Grills off listening is my preference. I could go on. But I would says this that you should listen to both speakers yourself !
If you like the JM Lab sound, consider Osborn loudspeakers. They use the best of the same brand Focal drivers, possibly have more solid cabinets, and are much better value than JM Lab.

For example, the "Epitomes" with bass bins, while bulky, sound very impressive - natural, dynamic, hard to fault.
