Very cool! Flawless execution it seems.
I am currently designing a PP 6c33c amp as a precursor to building Lynn Olson's Karna. I am still not 100% decided on the front end, whether to use Broskie's Aikido variation of the split-load phase splitter with CF's (have to put 2 & 2 together from his website) or use iron phase splitting Amity style.
But before all of this, I MUST finish my UcD rebuilds and knock out the test baffles for my Arvo Part speakers.
