I've listened, lived and auditioned extensively a few lines of the JM Labs and Dyns over the years & I personally would go for the Dynaudios over the JM Labs.
I find the sound of the JM labs a little bit on the hot side of things. Details in abundance but I find the mids to be a bit thin sounding.While the higher models of the JM labs offer a degree of refinement over the mid range products, I still find it lacking in robustness.
The Dyns are more neutral, more robust mids and the bass is very good. However these needs to be careful placed because they can be quite bass heavy at times.These speakers also crave for lots of good s/s power,.
Currently though I'm more in the PMC, Harbeth, Spendor camp of speakers. While these doesnt have the high's of the JM labs, or the bass of the Dyns, the mids of these speakers truly captivate my listening experience. The midrange is remarkable clear and open, which I felt the JM Labs nor the DYns amissed. Again, everyone is entitled to their own opinion. This just happens to be mine which is subjective to my listening preference and listening room.
