Alpha Dac 1. Upgrade path?


What was done to create upgrade to 2 series?

I realize Berkeley stated the Series 2 has "new clocking and isolation technologies". What isolation techniques have they improved upon? New clocking? How?
Very early DAC1 cannot be upgraded to DAC2.
Check your serial number with Berkeley.
I don't own one. It's my "curiosity" about isolation? and clocking? improvements. New knowledge interests me and creates questions and ideas. Fun
