CAT Ultimate Mark Two upgrade?

Has anyone done the upgrade?...What improvements were made?

I have the CAT Sig Mk3 & have no experience with the Ultimate Mk1 or Mk2. However, I have spoken with Ken Stevens many times & specifically asked him what the Ultimate Mk2 was all about. From what he told me is seems that the main push in the Ultimate Mk2 is: better power supply & an emphasis on getting the timbral accuracy of the instruments & voices just right.
Hi Bombaywalla,
I am an overseas user of the CAT SL1 Ultimate Mk1. It seems the CAT has no web homepage. Could you give me the phone/fax number and email address of Mr. Ken Stevens?
