My new review for The Absolute Sound comparing AGD GAN amps with BHK300’s

And that load of crap about “unobtainium” audio GaN MOSFETS!!!  Gees Louis!!! Switching MOSFETS have been used in high dollar audio amps for DECADES!! GaN MOSFETS are still MOSFETS!! Most are very linear but the GaN have efficient on/off states. GaN have efficiencies for switching use at ULTRA-AUDIO FREQUENCIES, hence THE CLASS D amplifier!!! DUH!!!  

Whatever corrections or disagreements you want to make with the author would be much more effective if stated without all caps, extra exclamation points, and snark.

This hobby is full of enough drama without unprovoked hysteria. Take a chill pill, bro.

@wolfie62 Not really sure what you’re saying.  GaN FETs are clearly different from MOSFETs, and the performance advantages of the former have allowed amp designers to not only more seriously rival traditional amps but are now starting to surpass them.  When a company like Atmasphere makes a GaN amp that the designer in most ways prefers to his MUCH pricier OTL tube amps that’s pretty strong evidence that something significant has changed.  Again, not really sure what your point is here.

I enjoyed your review. Thank you!

Very nice review I enjoyed watching it. Very professionally done :-)

I really enjoyed the review for all the info and analysis. I actually have owned the Audions for about 1 years now and have gotten the upgrade tubes as well. The claims are true and the change in the faux tubes do change the sound signature very much like tube rolling.
