I am not closing off my mind. Obviously you have not paid much attention, or you must have missed that I even suggested to Madfloyd to try out the NADAC; I am curious myself how it would stack up against his superb analog rig:

But the fact is, I have blown a hole into your transparency claims by exposing the contradictions in your argumentation.
On the contrary, you argue from dogmatic 'technical' principle that, for example, your DAC configuration or the NADAC must be better than the dCS Vivaldi without having heard the real world result, and that they must be better than SOTA analog without having heard the real world result.
I'm not going to claim to have the superior DAC without comparing both. All I can say was the NADAC was designed with the intention to be 100% transparent. So was mine. Most audio products are purpose designed for coloration. DAC's designed for 100% transparency are the best DAC's to use with HQplayer. This is because you can add the coloration's in the digital domain to suit your tastes. But they also can be taken away if they don't sound good with the particular album you're listening to. People are so used to the old school compromises with hardware based coloration, that they have a hard time realizing how much of a better world it is when they can be toggled on and off with a click of a button, rather than swapping out an amp, DAC or preamp.
What I would like Madfloyd to do is to try the NADAC, or even the low cost Hapi, in conjunction with HQplayer, before deciding to pay big bucks for the DCS. It may be an eye opener that will save him big bucks! If he doesn't agree, just return it.
