yeah, and there's also the theory that any scaling of any kind is innately bad. if you can't add resolution to what's been recorded, then all you can do in changing it is introduce artifacts and make it worse.
not that this matters. there should be literally no audible difference. i mean, maybe if you had perfect hearing and a set of 7 full-range martin logans in an acoustically perfect room, you'd be able to detect some shred of difference. but under even remotely normal circumstances, if they're from the same 16-bit master, there's no way. if you hear a difference between them, there may be some difference in how your hardware is handling the two different formats, in which case, just stick with whichever one sounds better to you.
