I do own the LRM-V and I love it! It's actually the main reason I don't own an R84... it does what I need a ribbon to do. And I can borrow an R84 from a friend if I ever REALLY want to use one for something specific.

The LRM-V can actually sound quite similar to the R84, but only with a fair amount of high-end boost (which it can take very naturally). One thing I like about the R84 is its surprisingly good high-end detail capture, and I like that it isn't as rolled-off on top as the LRM-V is. You get tons of the classic ribbony rolled-off high-end in the LRM-V, and that makes it a better contrast to my various condensers, vs the R84. But a modest amount of boosted highs for the LRM-V gets it crazy, crazy close to the much pricier AEA.
