Soundlab speakers...how reliable?

I've had a similar experience. I'm the second owner of very early A-3s (serial# A300****44.) I purchased them ~10 years ago, replaced the Mylar and they continue to sound great; better with the torrid upgrade. In the the past decade I've had no substantive performances with them.

I may have one of the earliest functional A3  Sound labs.  The serial number is A30044. I’m the second owner. The first was a florist in the Washington DC area..  Upon purchase I had new Mylar installed. The speakers have performed flawlessly for years. I agree  the superb customer support Dr. West and colleagues is without peer. I’d be interested in hearing from other  early vintage A3 owner’s. ARS
