JRiver MC 15 can also be used as a DLNA server!
That's of course fine--I understand the practical matter of the tedium of re-calibrating the PJ for the Denon. It would different if the PJ had enough individually calibratable inputs for each deck but I guess it doesn't.
But that practical concern and personal preference aside, the science of the matter as I understand it is that this is not a fair evaluation of the Denon on its own (de)merits. It's a comparative analysis using other players with different chipsets as "reference."
