I'm comparing it to the real hardware (at least as far as NES and SNES goes...).
A/O *is* extremely accurate overall, but I still hold that its output is slightly flatter than what actually comes out of the consoles - I wasn't implying that the distortion of earlier models was more accurate, I just meant that they were shooting at 120%, while it seems like the new versions are closer to 90%, if that makes any sense. And as far as NSFs at least, the noise channel's attack is a bit too short to my ears; games like Asterix which have fairly refined channel interplay sound noticably less staccato and more muffled than they do coming out of my ol' NES. Maybe my NES is haunted by a 18 khz ghost.
anyways, it's still the best program of its kind out there, so this isn't a complaint, just an observation that I wondered if anyone else noticed.
