Sorry, I don't know what TOS 8 is. That's why I'm here - In many respects, I'm still an audio newbee. Can you point me?
Here's the reason why - clipping or at least significantly higher distortion just below FS is not that uncommon. However, its relevancy to listening enjoyment is most people's primary concern. . .
. . . But its audible consequences for clipping in the last dB before FS? Not so much!
Ok, I can accept that.
However, in the case I cited, the clipping was serious - far from FS. I wouldn't have tested otherwise, but as soon as I plugged it in, I could hear something was wrong. The audio was seriously distorted. I would have just trashed it, but I bought it to test something else, and had it apart anyway.
Long ago, I generated a bunch of full-scale sine waves in FLAC that I use for testing the hardware that I design. On the scope, the 1kHz wave was clearly flat-topped both top and bottom. Reducing the gain of the output buffer was all it needed.
So maybe the hardware I've been building is not correct? I always leave headroom such that a full-scale signal will never clip, even with worst-case tolerances on the components. Am I being too conservative?
