Wacky AGD class D with GanFETs in a tube

[dougi]

Hifi News has a review of this very expensive class D with some measurements. Seems to use an Infineon Merus driver with the GanFETs output switchers in a tube bottle. Good power but doesn't seem state of the art in measurements, but interesting with slow rise in distortion with both power level and frequency. Still seems a bit load dependent in terms of frequency response.

That is really silly. At first, I thought this was some sort of solid-state device meant to plug into an octal socket in a tube amp, but it’s not. The tube shape and octal jack is just . . . artifice.

If "Tube Sound" Is a Myth, Why Tubes?

^This^. Yes, certainly could be. Though....expectation bias remains an uncontrolled variable until it is identified as THE significant variable and source of the perceived differences. In other words: could be sighted bias, could be real sonic differences perceived, but before doing blind...
