Are you saying that when you record amplitude in dB as a function of frequency for the whole length of a track it shows transients ? or are you saying that transient should have appeared as phase shifts ? Another non sense or I'm missing something pertaining to transients in anything you posted ?

You’re missing all of DeltaWave null analysis which is done in the time domain on the recorded signal. There’s no transient in the null recording, so no transient at the output of the DAC.

there is no measurement of how transients excite the room differently whether the feed and thus the path inside the DAC is PCM or DSD. If you believe that measuring the phase is a correct measurement of transients and represent correctly how the room and thus our ears react to music impulses, please explain
For us to hear a difference there must be a difference in the signals fed into the chain of reproduction. The null testing indicates the differences that are there are very, very small almost down to noise levels. Meaning any differences at the speakers is also very small. So the two paths put out a signal so similar the difference in anything exciting the room is also highly similar and we'll not hear a difference.

For what you are holding to be the case, you need some new measurement which is being missed by this null test, and I have no idea what that would be nor are you giving us much reason to think you know either.

But if there is no difference measuring the DAC outputs (no room involved), doesn't that say everthing?

Or are you saying the difference between PCM and DSD is caused later in the chain? Amp/speakers?
