S3 and Sigma - Any users?

[Dizzi45Z]

I'm trying to figure out what direction I want to go with my next Mixer. The SSL Matrix has looked very tempting to me, but if it works well, it seems that an S3 with an SSL Sigma would be more ideal so that you would get the tight integration of the S3 with the SSL sound, control and monitoring from Sigma.

Is anybody running this set-up? If so, how is it working for you?

My area I keep getting stuck is that I use a Hearback system which requires that I am able to split the outputs to the Hearback system (Pre Fader), but with talkback somehow integrated.

Anyways, I'm curious how it works for people who may have a similar set-up.
