I don’t think that I have ever posted about new firmware. This is outrageous. Currently across the room from my III is a vintage 1987 plexi. I adjusted nothing except the volumes, and it is dead-on. More important, my 1987 is one of the best sounding amps. My muso mates and the two best local techs would kill for it. And here it is, inside Cygnus. I’m super surprised.
