Just a quick test.  Wanted to see the quality of glass from Corona and I am happy with it :-). 

So here's the raw render and one with some very rushed post.

I left this running overnight - 8 hours - but still getting some noise.. Any suggestions?

PT+PT Progressive on i7 920 - 2.6-3.2GHz

Just an update/question.  I left this to continue running for a whole day and it went up over 1000 passes, yet there was still a big noise problem.  Can anyone suggest anything?

You should probably post render settings and scene screenshots when asking why so much noise.

Did you adjust the contrast in the post-processing options?

If so, don't do that. It looks like you're getting a lot of black clipping. That'll increase the amount of visible noise.

Thanks for the replies.  I've attached the model with the studio HDRI that I used.    Also attached is a screenshot of the settings.

Yes I did adjust the contrast so maybe that was it.
