1markr,
Interesting journey you're on!
I guess I'm missing a piece of the puzzle. Please backtrack to when you had Berning & Merlins. When the Aero dac didn't please, you added the Ultraverve, right? Sometime later moved to the Modwright. Did you use the Ultraverve or Modwright w/the Berning/Merlin combo, & if so how did the preamps compare with those components? Also, were any of your power cable experiments on the Berning? What did you try/conclude? Thanks,
Spencer
