Have been burning LTD in for less than 20 hours so far. They sound quite good, a big step up from ATH-M50, which has been my main closed hp (a workhorse for DJ gigs, but not really hi-fi). In general I prefer the sound of open hp's like HE-6 and HE-500, but have been searching for a "good enough" closed headphone for late evening listening when the wife is already trying to sleep. Open hp's generally leak too much. A900XLTD does not leak, or so little it does not bother others. There is definitely enough bass on 900XLTD, but it is not boomy. I am not yet 100 % convinced with the highs, however.
In Tokyo the LTD's were less than 300 dollars which I think is quite reasonable for the quality. Of course they cannot be twice as good as the normal A900X, which is half price. But are they worth 439 dollars? For that kind of money I would probably consider W1000X, which seems to be available for 399-499 USD. I have ATH-ESW9A for travel use and I love them. The highs of the woodies are better than on A900XLTD. Maybe the highs get better on LTD after more burn in, but the W1000X might be more refined still.
