I got a reply from the Reason suport team relating to this issue, and the web article.

Apparently 'harmonic distortion does not occur in the digital domain'. So there. :P They also stated that 'I don't think our developers put these kind of sound harming algorithms in the 2.5 upgrade.'

Hmm. Anyone else see the problems with these 'answers'?

The 'test' they propose to clear up the issue involves loading your favourite music into NN-XT and a samapler in Logic/Cubase, and playing them back to hear if there's any difference.

No help for issues relating to timing and heavily layered samples then!

They also asked if the Reason demo files sounded at all 'dull.' What's everyone's opinion on this?

I will keep you all informed of any further gems from the Reason team.
