I would go further by saying that digital sound reproduction has not been evolving since 1992. In that particular year four companies introduced their reference digital units: Wadia with the 7/9, Krell with the MD-10 transport and Reference 64 DAC, Goldmund with the Mimesis 10P and Accuphase with the DP-90/DC-91. After these efforts: no news actually. What was their secret? Meticulous enginering and implementation of technology and superior design of the analog section. You might not agree with this statement, but you have to concur that those were the days.
