Yeah, think this build definitely turned out to be more work than he thought.
But I have to say that each improvement in the prototype has been worth it, whether it's been the power supply or the partial silver transformers.
I've been lucky enough to hear it now and then as I often visit LA for work and he lives pretty close to my parents.
It is definitely worth the wait which is why, though impatient as everyone else, I am sorta ok with it.
To me, it is definitely a statement product and favor it over the ZD/ZDT which I also got to briefly demo.
