Maybe since you’re now on this thread, could I ask you to share how you voiced your GaN monos, especially in comparison to your OTLs? Did you attempt to preserve the same level of openness and bandwidth to your other amps (albeit making it easier to drive speakers with)? How would you compare the sonics of your GaN amps to your OTLs?
@blisshifi We did not 'voice' either our OTLs or the class D. Most of the work on the amps during R&D was to eliminate noise. We lucked out in that once we had that bit sorted, the things that cause distortion in our circuit tended to cause lower ordered harmonics, much like a tube amp, but at a lower level. I prefer the class Ds to our OTLs, once they have broken in. They are more neutral but easy to listen to; when comparing side by side the big difference most people comment on is the class D seems a bit easier to hear into the rear of the sound stage; they are more 'focused' if that makes sense.
