To follow up, I heard back from Mr. Gatski today and he will be sending the preamp back for upgrade in a couple of weeks.
He reports he has had several offers from audio pros to buy the preamp from him, but has declined because it is his favorite over the past decade.
I just hope we don't screw it up with the improvements and give him back something he does not like as much.
Gonna do it anyway, that has not happened yet hereabouts.
