GaN Amplifiers

Had a good question from from member @MikeM

Hi Alan, I am not sure how to start a new post, and equally unsure which thread this question might best be placed.

Thank you.

Hi @MikeM

There has been a lot of "noise" regarding GaN Amplifiers over the past few years, that they will offer some kind of leap in amplifier performance and sound quality, but the simple answer is that this just isn't true.

Yes they might in theory be able to offer some small improvements in efficiency and raise switching frequency, but there is a lot more to a class d amplification than that.

The fact is that there isn't a GaN based amp on the market that beats or even comes close to matching the technical performance and therefire sound quality of the Purifi mosfet modules that we use.

Gan is more expensive, so there has to be a compelling reason to use it. So far there isn't. Purifi may of course in the future implement GaN technology, but it would have to be a genuine worthwhile improvement over their current designs.

Bottom line, don't believe the hype. Just compare the performance of a GaN amp verses a Purifi module.
