Thanks for the input. I've been glancing over the marketplace here to see if anything pops up, so I'll keep my eye out for that too. How's the soundstage on the shures though? One thing I really liked (amount many others) coming from my m50s to the 990s was how airy and open things sounded.
Soundstage on the Shures is excellent. In terms of sheer detail, I doubt anything can beat the Shure in it's price range. I have a virtually new pair up for sale if you're interested.
