Atmashere when was the last time the class D mono blocks
were Officially upgraded or improved ? AGD for example has had 2-33 upgrades that are a noticeable step up in sonics depending on model.
there has been several new Gan Mosfets in the last 2 years just an observation .
@audioman58 We spent about 5 years refining the amp we released. It had to sound better than our tube amps, else people in the market might think we were nuts or just cashing in. Plus I wanted to enjoy them in my own system and not miss the tubes. We met those goals and so the amps haven't needed refinement since release. I can't speak for other manufacturers in that regard- each follows their own path. Its not as if we are sitting on our hands though. We switched to some newer devices in the 2nd year of production as they made our heatsink more effective. That required an entirely new module. But it does not sound different from the old one.
