I just use my ears instead of calculation.
The increase in body, depth, definition is massive, when comparing
an identical multitrack session between Logic Pro and Cubase (6).
Regardless of floating point whatever. Just try it out. Its the only
test that works when in danger of getting lost in technical data
comparison without the ability to verify in detail, what
manufacturers tell you to sell their software. Called ears.

That's quite a lot of assuming, Jay....
Let's talk about Protools HD, OK?
For starters, the "HD" fixed point audio engine and headroom.
0dBfs = clipping.
Try a simple experiment.
Insert a 20hz HP filter across a 100hz sinewave in Protools HD
while monitoring the output level on an Analog VU meter across the
stereo bus. When you engage the HP filter you will see a 3-6dB
increase in signal level on the analog output for a signal that
shouldn't be affected at all by that filter.
This sort of signal condition is happening on every channel of
Protools HD and the net result is that you run out of headroom and
the signal clips, though the Protools meters won't reflect this
because it's caused by intersample math overages.
Logic, on the other hand uses a floating point audio engine, this
gives over 1500dB of headroom, and retains the full 32 bit audio
data at any attenuation or boost in level. That is what I call a "
a properly programmed audio engine", my friend.
But what do I know... ;-) *
