freaky,
i just received my cx-7 back from ayre. i have a b series (early model) and the upgrade cost $650 because they had more to do. according to steve ayre customer relations dude, "The B series requires a fair amount of upgrades to be brought to current spec. The New Transport is much quieter and smoother in operation. To be honest, the new DVS drive sounds better too. A Daughter board is added to the under carriage of the audio board. This new board beefs up the voltage regulation and yield a firmer, more resolute presentation. It's puts some confidence in the presentation. New firmware and hardware are added to the logic board. A new DSP algorithm that we wrote sound much more sophisticated. The final nail is the Dynamic Power update. Dynamic Power includes newly developed circuitry that increases instantaneous current delivery, reduces mains-borne RF interference,
and eliminates residual switching noise from the rectifiers themselves."
the evo upgrade is substantial, and well worth the money.
