Upsampling: what's best?

[christoffe]

Brian, I understand now.

Possibly you are not familiar with the phenomenon "airy" or maybe better "with air". This is how all is going to float with "see through" and more I too can not describe. But it looks like something very different from what you describe.

Thanks,
Peter

HI,

airy

Pertaining to treble which sounds light, delicate, open, and seemingly unrestricted in upper extension. A quality of reproducing systems having very smooth and very extended HF response.

Thanks guys, what I'm talking about has more to do with the mid range, so airy was definitely the wrong word.
