If I understand it correctly, Cubase VST 32 is capable of recording 32-bit audio, but all 32 bits are represented correctly if, and only if, your converters (and anything else in your digital audio chain) are also 32-bit. There's still an advantage, however, when it comes to cumulative headroom.

If true, would using the 32 bit recording option make it easier (or better) for the computer to manage the sound data? Is this the advantage of using this option? (or is there any advantage?)
For example, say we record an acoustic guitar at 16-bit. It sounds good. But then we add a reverb and a delay and an eq. And 48 other tracks with reverb, delay and eq. A ****************ty mix notwithstanding, all of these tracks quickly add up to clipping the stereo mix bus, which'll force you to start turning down channels and aux returns. No problem, that's fine. But at higher bit rates, you're able to turn these signals down and still maintain high sound quality, since the bit rate to begin with was high enough to give you room to move down without worrying about running into all that garbage that lies down in the low levels of a 16-bit signal.
On a tape recorder, if you record too low, and then turn up the track, you'll increase tape hiss. Likewise on a digital system, if you record too low, and then turn up the track, you'll increase digital garbage. If you record 24-bit (or implement an engine at 32-bit, regardless of what bit rate you're recording at), you're effectively pushing down the volume at which you'll begin to hear that digital garbage. In practice, a smooth fade out at the end of a 16-bit song, if listened to very carefully, will sound a little grainy at the very end, where a 24-bit song will fade out longer before dropping into digital garbage. If you want the reason why, read Duardo's posts. He's definitely knows what he's talking about.
