My uncle is a Audiophile as well as myself and designs in pro audio, class D has made its mark the Gan circuits can be good but
the design circuit also has to be created and voiced also properly around it.
it will progress over time ,but still in its early stages .in many cases the good old Vacuum tube which was called obsolete back in the 80s still in many areas still is the standard for realism and naturalness.being part of the audio circuit in a Power amp, preamp, or in digital there is a magic hard to ignore.
