Hi...nice system!!! the stuff of legend. Enjoy!
Since you are using Transparent Audio...have you heard the Transparent Audio Reference Series? XL or regular? older, XL, MM1 or the latest MM2? I have not heard your particular Z2R,...but i have heard older Reference, XL, Reference MM1 and Opus MM1. I am very impressed...own second hand older Reference and Reference XL. have not changed in several years and no desire to.
