When your audio leaves your DAW, anything over 0dBFS is going to be clipped at 0dBFS anyway.
You can export 64-bit floating point WAV audio data and Sonar will save all that data faithfully up to +100 db or whatever the max float number is (10**308 IEEE 754).
It's just that very few things are around to use that kind of data.
Sound Forge can read that data and manipulate it, but it will not display beyond 0dB, it looks like it clips because the display does not zoom. Neither does the Sonar track display as far as I know. But the data is still valid.
This is an unfortunate residue that comes from the tape oriented background of pro audio.
True digital audio has a very wide gamut, our physical transducers are far more limited.
