ADA4899-1, anyone else tried it?

I think this amp has great potential. I've never heard an opamp with such clarity and transparency. Especially it makes voices clearer than anything I've heard. It doesn't sound like and opamp.

I use it in a headphone amp with active ground channel, no buffers. All 3 ch are ADA4899-1's. The only problems are lack of soundstage (a bit narrow compared to the best like LM4562, AD8066, AD8397 and AD744) and lack of warmth and maybe slam in the bass (you know, that "organic" sound). I guess it's bad implemented because my lack of knowledge. Maybe I'll try it buffered sometime. I think it's a bit similar to LM4562 but with better mid/presence and clarity = less colored sound. The sound is similar to AD8099, but that one I could never tame, very unstable and a minimum of 50 mV DC-offset.

Has anyone else tried this one?
