Wasn't there a way to actually run 14-bit sound? Or is that what you guys are saying?
Yes. I use 14bit 56khz Audio on my A4000, no problem. All system friendly AHI aware apps run perfectly. And with 060/50 the CPU load is not noticeable. (IMO, the paula audio is better than standard AC97 on x86, less noice on the sound + my ears can not tell the difference between 14bit and 16bit)
For old games and old audio apps, only basic 22+khz works, but 14bit is possible if application supports it directly.
(for 56khz you need multisync monitor for AGA output or separate GFX card like I have ... actually I have both, but anyway.)
