Alpha Dac 1. Upgrade path?

I realize Berkeley stated the Series 2 has "new clocking and isolation technologies". What isolation techniques have they improved upon? New clocking? How?

Perhaps someone knows of an article that I can access?

I don't own one. It's my "curiosity" about isolation? and clocking? improvements. New knowledge interests me and creates questions and ideas. Fun

Thanks for your user experience Rja. It seems I've heard similar comments before. It encourages me to consider an economical, older Alpha Dac 1. It would likely be a great step up from the Lexicon RT20 I presently use.

Thanks Rja. Makes sense. Cheers. Pete
