Back in the 1980ies Snell sent me two new 10 inch woofers for my c2 mk 2 when only one was needing refoaming for 250! But my best story adcom I had their cd player it would skip and the big power amp which I inadvertently shorted out, both units will out of warranty. They were located back then in New Brunswick NJ just 30 min from my house. I drove up and they fixed both at different times each time for a dozen donuts. both the Adcom and Snells worked up to this day when I sadly sold them to afford newer and more contemporary offerings.
