Well I ordered the TH900, waited 5 weeks and received them. Now with the DX100, where I had to go medium gain maxed volume or high gain half way (depends on the recording) with the LCD-3, and even like that, sound was a little on the thin side ( none of that bass i'm used to with the LCD-3)the TH900 works on low gain, and between half and 3/4 volume, and no problem with the bass at all, very punchy and dynamic. But there`s one little thing; even though I burned them about 60 or 70 hours, I still find the high end on the bright side, and can`t get used to that. And if I listen a long time with the TH900, I find the LCD-3 lacking clarity or something. I guess I got so used to Audeze sound for last couple of years with the LCD-2 & 3, and now find other HP bright on the top end. Maybe if I had the Fostex first, and then tried the Audeze, I would find them too dark. So I guess I`ll be putting my TH900 for sale on ebay, and if I`m lucky to sell them, I might get the LCD-X, which is half way in sensitivity between the LCD-3 and the TH-900.
