Thank you Silent One! its really really hard not to want the TH900s if you have ever been a fan of the D7000s. I always loved my Denons and these were the most natural upgrade, the price is definitely steep but the way I see it, if you can sell some audio equipment you see this replacing (as I did) - its worth it
.
With the 6SE the TH900 sound great, the bass is remarkable/even better than the famed LCD3 and Signature Pros in that area (at least to my ears), but the treble and mids seem more neutral, not as liquid as I was hoping, but I feel that may be my amp. the 6SE has always been pretty neutral with all my headphones. Hence my questions about the WA22 and WA5LE, not that I can afford either right now, but maybe I can save up in the coming months.. and here I thought the Fostex would satiate my spending appetite for a while...
