Anyone heard anything about the evolution 50D and 50A?

More interested in the 50D as they were designed by John Westlake and Dominik Peklo of Audiolab MDAC fame.

I've been interested in the MDAC as an upgrade to my current source - the popular schiit bifrost, but maybe I'll wait until Westlake's newest creation comes out.

Quote from the Creek Audio site:

"The EVOLUTION 50D's contains 2x ESS SABRE DACs running in a 'Dual Differential' configuration, for increased dynamic range and lower noise. The balanced audio output of each DAC feeds a discrete transistor 'Class A' current regulated 'CROSSII MOSFET' buffer circuit, that also acts as a 'Class A' headphone amplifier output, controlled with a digital volume control. Expected availability is from September/October, depending on region. Priced in line with the Evolution 50A at £550 in the UK, including sales tax."

Anyone have any experience with Westlake's products - specifically the MDAC?
