Once in a while a normalize a few lossless files which need some volume with Adobe Audtion or DBpoweramp. I want to achive the maximum volume without clipping of course. So can I be safe with setting a setting of 0db? Or should I stick with -1dB?
I've tested a goodly number of DACs, and its not uncommon for them to clip prematurly or start to distort before FS. Normalizing to 0.5 or 1 dB below FS doesn't hurt overall loudness, but it eliminated the possibility of these kinds of distoriton
Many devices exhibit a prolonging effect every time 0 dBFS+ is hit even briefly, thereby making a short transient overload worse than it otherwise might have been. The cause for the sustained distortion (often 150-600 ms) is believed to be analog circuitry latch-up and/or recursive filters.
It's quite easy to document claims that CD players clip. Is there any evidence that can be presented?
Any modern DAC should have no issues with peaks at 0dBFS (aka 1.0 or -1.0 floating point), it's only when lossy formats are decoded and due to their (surprise) lossy nature that the peaks may go beyond full digital signal.

I took exception with your use of the word need in "If the decoded lossy is either 0.99989 or 1.0 then you should be fine, if it is 1.001087 (anything above 1.0) then you need to normalize to something lower." I'm sorry that I didn't include that in my quote earlier.Seeing that the OP is talking about lossless, I'm wondering why you brought it up at all.
