I completed building the stock Crackatwoa last evening and have been enjoying listening to it. It's character with both the ZMF Auteur and HD800S ideally matches my preference. It's transparent in the presence region, noticeably tighter in the bottom end than my Crack/Speedball and delivers explosive dynamics. Truly a keeper! Over the next couple of days, I'll do some tube rolling. A few weeks from now (or when the spirit moves me), I'll build and install the Two Quiet upgrade. And, some time after that, I will probably install a pair of 100 uF Clarity CSAs I've got set aside.
I'd be remiss if I didn't, once more, thank the Bottlehead crew -- Doc, Paul and Eileen -- for your comprehensive and methodical build instructions and support. As with my two previous builds, I find the process immersive and therapeutic. Can't wait to build my next kit(s)!
Be well,
Joe.
