Wow I walk away for an hour or two and y'all start fighting!! Lol. I gotta stop sleeping!!
I agree with Adam. As much as we'd all like the highest possible specs on these devices, we should all remember that at some point the human ear just can't tell the difference anymore.
For me, 44.1 is good enough. Hell, my digital recorder records at the same rate, and I've never heard a complaint that it sounded bad.
The focus needs to be on the headphone jack. What I mean is that thanks to the Apogee and a few other interfaces, we've got a great input signal, now we need to focus on retaining that on the way back out of the device.
Snobbery can't exist here, since we're all in the same boat. We're all trying to get the best possible sound out of our rigs, so getting crazy with the details IS important, but lets also try to be realistic.
How good is good enough?
