Siltech SQ-110 Classic MK2 question.

I have the SQ-110 Classic MK2 running from my CD player to the Processor, really like the sound. My question is, the new SATT version, is this an upgrade process or completely new line of cables? I have seen the older cables than my with SATT(Siltech Advance Thermal Treatment). Did they get upgraded or what? and if they can be upgraded, where and about how much that will cost? I like to hear it from Siltech owners out there.
