Fairlight-CMI

Hi Guys,


 From what I understand the CMI 11X had 4 different revision channel cards
made for it. 

Rev 1 Curtis Filter chip

Rev 2 Curtis Filter chip

Rev 3 SSM Filter chip

Rev 4 SSM Filter chip

I would like to hear from other owners what the actual differences are. I
understand that the Rev 3 and 4 cards should sound warmer. Have any of you
noticed this ? I have not actually seen a Rev 4 card,do any of you have this
revision? Is it possible to update a Rev 1-2 card to a 3-4 specification ?
Any info regarding channel card revisions would be appreciated.
 Thanks.

Regards,
