Anybody heard new Grace headph.amp/DAC?

If anybody heard or bought a new Grace Audio Design headphone amp/preamp/DAC,i would appreciate your feedback re this unit.Thank You.
i have recently purchased the grace 902 that i believe you are referring to... will be happy to answer your specific questions...meanwhile, let me say this, the versatility and refinement of the dac section along with it's already lauded capabilities make this new offering worth every penny!!
i use both senns. and grado's with this unit....
Can i use it as a one input preamp?
Power cord:is it detachable?
What DACs that you had before were outperformed by Grace?
Thanks a lot.
