Thanks Blasto. I forgot the thread as much as I forgot the haeadphones. I purchased 8900. I did a quick A/B at the shop I got them at. I could not find much difference in quick A/B. It doesn't mean that 9000 is not better. It may be, but I think good audio doesn't jump out at you right away. Once you get used to it and then switch back to a lesser product, you realize what is missing. So while I was fully bent on buying 9000 even with the price difference - there was only one set available and that was not in physically best condition. I ended up purchasing 8900. However, I am not using it much these days as my stereo/ projector setup was lying packed away, and when at home I prefer to listen on stereo so that I can move around.
I think I should bring it to office - thanks for pinching at the right spot.
