@dpm2340 Choosing between the two will come down to your sonic preferences. From my experience, Audionet is exceptional every step of the way, but it prioritizes a rich tonal density and balance (that many electronics manufacturers can only dream of achieving) over microdynamics and detail. Perhaps a better way to express it is that Audionet has no shame in delivering a refined sound. Constellation by contrast tends to come off more dynamic and will likely be faster on the transients, but at the expense of falling short to the soul that the Audionet Amp V2 can deliver. Of course, the higher up you go with Audionet, the control and microdynamics only continues to improve.
I’ve read a few reviews and posts in the past that communicate the Constellation Inspiration Stereo amp is not great with macro dynamics and bass. I would say no Audionet units are ever incapable of delivering those.
It’s not to say that Audionet doesn’t deliver detail, it’s just very different in presentation. And how either perform will come down to the rest of the synergy in the room.
