@neil_squires@neil_squiresand Tim, harmonic distortions lower than 0.005% have already been achieved in class D for a few years. One example is the Mola Mola Kaluga designed by Bruno Putseys using an enhanced NC1200 Ncore modules. THe amp is rated at less than 0.003% across the audible frequency band. The big Rowlands M825 and M925 amps also exceed the 0.005% target, but their price tag makes them somewhat more exotic.
The interesting thing in Gallium Nitride transistors is not so much whether they can in principle enable a high priced class D amp like the panasonic to achieve distortions lower than 0.005%, but if the technology could bring such performance in designs that serve the sub_$10K market, and perhaps one fine day, even below the $5K market.
On the other hand, the audible performance of an amplifier is not created by one particular measurement, nor by a slew of measurements, but by the effect -- iuntellectual and emotional alike -- that the device is capable of having on a listener... Plenty of amps of any class can mesmerize a listener, with a somewhat weaker link to their total declared distortion.
