Sad to hear. I recall when I first heard the MG-1's (I believe) back when I was a teen. Walked in the demo room and did not understand all the fuss. The I sat in the sweet spot and was floored. Bought a pair for $500. Not inexpensive for a teenager. Managed to upgrade the crossover with mylar caps (back then those were the bees knees). Jim was a great innovator and will be missed.
