There isn't an absolute advantage to using 192 khz over 96 khz over 44.1 khz, etc. They all are just different, and some prefer one over the other.

Gotcha.

i dont know much about it but i know the higher sampling rates are more convenience for studio and mastering work to edit the music.

theorically 192khz is better because it play the sample that much time per second. but if you upsample a 44.1khz to 192khz i dont see where the improvement is. if it was recorded as 192khz itself. i tried upsampling with mp3 on my chaintech and i heard a bit more bass with a small loss of details in the high.

however its the bit that effect the improvement much more than the sampling. i still am uneducated about how it work though.

Hmnmm...

Upsampling will defeat the purpose of bit-perfect. If you want as close to the original source as possible, output 44.1KHz from the AV-710 to the VDA. If you output to 92KHz, the AV-710 does the upsampling and may be worse off than bit-perfect.

I personally can't tell a difference from 44.1 and 92. So I leave it at 92 because it's a bigger number... poopsticks.

I am kind of confused. What is meant by a better digital out? If your sending a series of 0s and 1s it seems kind of weird that it matters which digital out you are using. Furthermore as far as I undersand it there is no such thing as bit perfect up/oversampling

. If its all a form of interpolation of extra points then it can't be bit pefect (unless I don't even have the right definition of bit pefect).

No point in the 1212m for digital as the 0404m is the same for digital (exactly the same PCI card even).

Not sure about the logic here! In any case the AV-710 won't do the upsampling - it will be done in software.

Think you are thinking of the 1212m and 1820m. The 1212m and 0404, no such beast as the 0404m, are vastly different both on the digital side and analog.

Oh, yes, my mistake

Even if a digital out is bit-perfect, the amount of jitter introduced may still vary. Low jitter is important during A/D and D/A conversion (and only there - digital transmission can have rather insane amounts of jitter, with no effect whatsoever as long as this is cleaned up again prior to D/A).
