Maybe it would be worthwhile to point folks at HKJ’s BLF17DD review? In that review HKJ goes to no great effort to explain the concept of “direct drive” and it’s implications - so reading his review will probably only help so much if a person doesn’t already know about those things. It can be difficult to communicate in an accessible way exactly how DD ends up functioning. Maybe lagman’s thread will help people better understand the concept and it’s implications. I’ve been meaning to review his writeup but haven’t done it so far :-(.
