I can only confirm
@NTTY's statement.
Over the past few years, we've conducted several hundred fully leveled blind tests within a project, including with dozens of DACs and CD/SACD players, the results of which agree with both Amir's tests and those of NTTY. These tests were conducted completely independently of those on ASR and are often very far apart in time.
We also had many guests and their devices with us, often so-called audiophiles.
Their statements never stood up in controlled blind tests, regardless of whether they were "a difference like night and day" or "much worse than other devices." Only when a device was defective or had extremely poor measurements were the results very clear.
Everything else was very close, even with audible differences, but not like "night and day."
So-called "sounded" devices can make an audible difference, which is also measurable, but must be considered defective because they permanently alter the original musical material/signal.
It should be clear to everyone that without tone controls or DSP, such a thing constitutes an uncontrolled and altering intervention in the original signal.
The excuses from the guests during these tests as to why even they couldn't hear the "huge difference" would fill an entire book. I was even once accused of tampering with their own CDs, which they had brought with them.
