I have either a mint pair of TH-900 cups or a pair of Lawton Audio cups (Walnut) for sale (I believe they fit on both Denon / Fostex, currently using a TH-600 myself). Please PM me if you are interested!
Sounds great! I'll have to wait until Schiit Europe (Sonority Audio, the dealer for the Netherlands) has one in stock... Seems like they expect one next week. Gives me some time to think about it too (although I think I've gone without a DAC for too long)...
