But the discussion here is not on an "established matter". Is it an established matter whether hi-rez or different sampling rates either can or can't be detected? I don't think so. Some of the scientific articles posted in this thread clearly contradict each other.
Which Swedish paper? Do you mean the discussion about dac testing from the other thread? Well, AFAIK
@Cosmik thinks obsessing about normal well-designed dacs is a complete waste of time, and I tend to agree with him (any hypothetical audible difference that well-designed dacs
could create pales completely when compared to the distortion and smeared time response one typically finds in normal passive speakers). For my part, that dac debate is/was mostly a question of trying to stay open to evidence which conflicts with my convictions. I have spent quite some time claiming on audio forums that all modern dacs sound the same, and I therefore find it interesting that there may be evidence that contradicts this conviction.
But in any case: Wishing you an excellent weekend!
