<OT> back in ~1998, I used a couple of SSM2015 mic amps in a broadcast
console.  Was _very_ impressed with performance.  Then used their stereo
VCA+sidechannel (forgotten the number) for FM broadcast processor
(gate/expand/compress/limit).  Both units are still in service.  SSM got
it very right. </OT>
