Not really, except that I spent a lot of time listening to the Rosa's several years ago at the Chicago HE show (I loved them). My comment was based on my impressions only, which include that the Egglestonworks speakers like a goodly amount of power, and that JM Labs speakers lean to the more efficient side. I may be wrong.
A lot fewer Eworks speakers out there than JM labs, but that doesn't necessarily reflect relative quality of product.
