I’d hope that 10 to 25 years from now, audiophiles will have access to great sound using these continually improved Class-D amps. That is after all why we all got into this, regardless of what technology we use to get there. Figure Class A, Class AB solid state, and SET or push-pull tube amps will be around for a long time, just because there will be some who will want them.
@moonwatcher Yup. My sentiments exactly. BTW I recently spent $$$ doing full upgrades of my McCormack amp (Class A/B) but came very close to going with a GaN amp. Came down to that I really liked the sound of my amp and the prospect of significantly improving upon that with SMcAudio upgrades just seemed like a low-risk option sound wise while switching to a different amp/technology might just end up being trade offs instead of a total upgrade. The devil you know…plus the upgrade was considerably cheaper than the GaN amps I was considering, so there’s that. It’s a journey fer sure.
