Ralph, congratulations for that. I knew it was some time ago you established Atma-Sphere, but at my age narrowing down specifics for time is not always easy.
I will only add that nearly 30 years ago I owned a pair of your MA-1 amps, 100 wpc as I recall. Within their limitations they were one of the most musically enjoyable components I ever had. Unfortunately because of the power requirements for my speakers and their impedance curve it was not a good match for complex, dynamic music. Otherwise the amps themselves were amazing and your support was exceptional. I remain impressed to this day.
Now back to tonearms. ;^)
