GaN-based Class D power amps

Lots of class D and class A and class A/B amps are better than the old Merrill Veritas......not a current reference. Listen to the $8000 Nuprime Evolution amps......these might give the latest GaNs a run for the money for a lot less. Then there is the latest (just now being released) version of the DAC Megacherry amp ($6100)......I am sure there are others, as well. We need some GaN amps less than $15,000.........I bet within a year we will see some. By the way, DAC and Nuprime each have their own patents on class D and make there own stuff.....no stock modules from other companies. There is no reason why a GaN amp should be any more than $100 more than a mosfet based amp. So, in a few years, you will see $500 GaN amps......even kits. I think we will see a Nuprime GaN amp within a year (it is in development now).

The most exciting thing about GaNs (assuming they make Class D better) is that you will be seeing more and more integration in audio. Imagine a 2 or 3 channel GaN amp inside a speaker with digital input circuitry, electronic xovers and room eq. No more speaker cables, analog line cables, multiple power cords, racks, etc. You just have source and a couple of Ethernet cables going to your speakers with built in everything.....including GaN amps. We are talking super sound for the masses. The source box would have an A2D converter to convert your phono stage (or other analog source, if any) to digital to run to the speakers......very cool. Cannot wait.

Yes we have also tested the Class D Nuprime Evo amplifiers and the new Evo dac and both products tested well above their price points. We are still testing several different Class D amplifiers in 6 different systems and this takes time for obvious reasons. Currently we do not feel that there is any advantage, Class D GaN amplifiers have over other top Class D amplifiers, based on our direct A/B testing.

George,

Measurements mean very little......you must listen, listen and listen some more.....for reality.  Of course, really bad measurements are usually detrimental......however, what constitutes bad measurements?  You would have to listen to determine that.

I think GaNs will make class D better (everything else being the same).  However, we are in the infancy of their use.  Every GaN and every mosfet based class D amp will sound different as everything you do makes a difference sonically.  We have years of perfecting yet to come.

These first GaN amps are just the tip of the iceberg.  We will see relatively inexpensive GaN amps that blow these expensive first offerings away......no doubt.

Cannot wait for Worldwidewholesales to finally tell us their comparisons of all these GaN and non GaN (mosfet) class D amps.
