Damn, have been out of the loop for many years and literally just stumbled on this news on Rich's site. So sad.
I bought a pair of TSM many years ago (15?) and went through every upgrade I could over the following 10 years or so. I think we shipped the speakers back and forth, in the original (and awesome) cartons four times. This involved many a conversation with Bobby, which also led to my purchase of a Filarmonia as well. Every conversation with Bobby was an adventure, he was such a character, but I've never met a vendor with such a love for his product AND his customers. He ALWAYS had time for us, and to this day I am enjoying the TSM/Filarmonia combo as my primary music system.
Bobby was, as they say, sui generis - after they made him, they broke the mold. Passionate, eccentric, a bit of a curmudgeon (the good kind!), but dedicated to his craft and his customers. What a sad loss for us all.
