This may muddy the waters a bit, but it may also be useful to consider the Totem Mani 2 (reportedly finicky about its electronics), the Totem Tabu (great little speaker), the Induction Dynamics line (their little 3000 dollar monitor I heard in Naples, Florida was GREAT). In terms of JM Labs, I've heard the Micro Utopias which sell for around 5000 dollars. If THOSE are the JM Labs you're talking about, then, yes, they sound very good. However, IF you're planning to spend THAT much money on a monitor, then I'd strongly suggest first listening to the Intuitive Design Summits, which go for around 5000, INCLUDING the stands (about 3500 for the speakers and 1500 for the recommended stands). However, the Summits are NOT a good speaker to listen to after having purchased a different speaker that you thought sounded good, in my opinion.
