Thank you for saying that, and for your PM to me. I'm a relative noob here compared to many of these members. But, I'm a fan of the DJ and DD models and have purchased and sold a DD2 along the way. So, if you'd like another set of eyes on your QC, I'm happy to help. FWIW, one problem doesn't necessarily indicate other problems. And, in an imperfect hobby as this, there's quite a bit of variability all along the supply chain. What is encouraging is that your TD brought the crown-issue to your attention and not the other way around. That definitely breeds confidence. Cheers.
