I am sorry I asked the question. I was looking for an engineering viewpoint on whether these claims - and others from other dac manufacturers - make sense.
I have been an audiophile for years and never could hear a usb cable. I don’t buy anyone can hear the difference in double blind tests unless maybe the receiving device is faulty or poorly designed. Some of the best dac manufacturers have told me to use a “computer cable”.
However I am convinced of the differences I hear in dacs as I have done tons of double blind, a-b and non blind tests where my consistency (and that of all others in the room-this isn’t a claim of golden ears) was conclusive.
Maybe it wasn’t the dac portion but the analogue one - no idea. But I’m talking about devices where the measurements I believe exceed the levels that we all think here are audible. An accuphase d90 dac was consistently chosen as different than a Scarlatti DCS one. Both measure way better than we claim we can hear.
This can be dismissed in this forum but that would be unscientific. Reading the very strong view in this forum that a 600$ dac can’t be beaten I did look into double blind test psychology and there is certainly a view that the brain can act the opposite way during these tests and start to normalise what it hears so long as differences are small enough.
I don’t know - haven’t done the research but if we believe the brain plays games towards one direction it would not be mad to at least consider it can also play games the other way.
What I don’t understand is the vitriol here on things that are irrelevant to the scientific / engineering question or argument. Presumably we are all seeking the truth?
Not that many people here are digital experts and even fewer are DAC designers, if any, and those that are would need to see schematics and detailed theory to fully comprehend what is supposedly being done in this gear using a plethora of bleeding edge test gear.
But of course, seems no one here is rich enough to purchase this device and have folks over for some sort of blind listening test either just to answer your query. However, anytime you put user controls on a device, and let the user adjust it to taste, then things are being manipulated from "normal", like tone controls on a pre amp, thus the whole product comes into question in my opinion, if it is the best out there, why the need to make adjustments, by EAR, to compensate for things which most of us would say can not be heard by most anyway.
I do believe you can hear differences between extremes of components, in your case DACs, but what difference you hear is "correct or accurate to the source" anyway: how do you know!
I understand you were looking for a detailed tech discussion but again a whole lot more would need to be shared by that company and you would need to find the person who has nothing else to do but spend a great deal of time and testing to be able to validate this stuff.
I am not sorry you asked the question, just that it is kind of a huge ask, all my opinion of course.
