RevD is still minimal phase I bet? Do you have any results in a comparison of sonics, RevC vs RevD? Dave got his HOLO Spring L3 Monday but hasn't had a chance to do any serious listening, plus it needs a little burn in. I'm hoping t make time to visit Chuck's with you Monday post RMAF, TBD.
We should be able to have a great comparison day at Dave's post RMAF, I think I can get an AQUA LaScala III, and my Comet Plus in addition to your RevD and the Spring L3.
See you in CO!
