Excellent info. I was reading a couple of interviews with Dr. Hsu today (pre-LFM-1) and he spent quite a bit of time in one discussing his engineering as the intelligent selection of compromises. What he did differently from other companies. One can certainly see some of his philosophy in the LFM-1. And one can see some well-reasoned departures in the LFM-1 from what he has done in his own products.

A question that might elucidate a non-obvious design choice: I haven't taken my LFM-1s apart, but from the exterior shape and another clue, it appears that the main casing is a cast resin material? One reviewer referred to the "MDF cabinet" but I'll bet it's not. Or may be MDF cast in resin. What is the main casing material and why was it chosen?
