And, when you wack it down to 16/44k in a mixdown, it sounds worse than just using 16/44k from the beginning in my experience. No, Dithering helps, and its what about everyone in the entire recording industry does. How many albums you think are tracked straight into pro tools at 44.1/16. I bet none in the last couple years. I hate to get masters in 16/44.1, id much prefer a higher sample rate to play with until I dither.
