What Im saying is I dont believe the improvements in the convertor would be noticeable at all.
Perhaps someone with the most excellent acoustically treated room and most excellent speakers could tell a difference at a push.
So you don't believe anyone will hear a difference... except those with good monitoring envirnoments who might!
However, I agree with you that modern converters and implementations are generally so good that incremental technical improvements are often extremely subtle, and superb monitoring environments are now required to really appreciate them.
Your taking Apogees word there's a noticeable difference and this of course is exactly what their banking on.
It would be a foolish company that made bald claims they couldn't back up, although I suspect the major audible improvements will be in the preamp performance, rather than the converter performance -- although having said that, clocking can have a radical affect on converters and small improvements there can be surprisingly audible.
I've not heard the Duet 2 yet, so this is only speculation on my part, of course.
Its like Dither. No one can actually hear it doing a damn thing yet some will say I prefer Dither mode fantasy 3 for its deep wide analog style sound. Do you hear Dither working when truncating a 24 bit file to 16 Desmond?
I don't know about Desmond, but I have certainly heard differences when switching between different dither algorithms -- the results are very dependent on the material being processed: some makes the differences far more audible than others.
In a blind test nobody on this forum would hear the difference between the two Duets monitoring the exact same song.
You might well be right...
Yet , we will soon read reviews of a much more open , wide, deep sound etc blah blah. All of it will be Placebo effect.
Let's wait and see, shall we....
