GaN FET Amps vs. Traditional Class D Amps

I'm trying to get a better understanding of GaN FET amplifier technology. Whenever I see a write up on GaN FET based amplifiers they are always compared against class A or class A/B amps. What I'm more interested in is how they compare to the current generation of 'traditional' class D designed amplifiers, both technically and sonically. Can anyone explain it to me?

 

Thank you.

First you would have to describe what is meant by 'traditional' class D designed amplifiers.

All "traditional" Class D amps do NOT sound the same.  You have to compare specific models.  The devil is in the details.

In general GanFet  ups the ante in terms of performance level possible. Does not mean all GanFets are necessarily better.

I have several Class D amps including Hypex Ncore,  Class D Audio GanFET, and other chip based Class D amps. Have owned "high end" Icepower in the past as well.

They are all good but each different.  The Class D Audio GanFET is the best performer in all regards.  HYpex Ncore is no slouch but sounds clearly different.  That’s just one specific Hypex Ncore amp.  There are many designs  at various price points with different power supplies, opamps used, etc.   You have to compare specific models to draw any meaningful conclusions.
