I work at 48kHz with audio files at this very same sample rate and 32-bits FP so based on my experiences and listening tests:
2) Let Nebula convert programs to 48kHz
Nebula's SRC is VERY good, I don't hear ANY problem with it. There are users who claim they can hear it so maybe you should do your own listening tests and decide for yourself. If you hear a difference think "is this difference a justifiable reason to tax your CPU at 96kHz and work with less Nebula instances and cripple your workflow when you're in fact achieving better results than before at 48kHz?" Even after conversion, Nebula sounds better than most plug-ins.
