LSA Voyager GAN Amplifier

Just got mine last week.  After 24 hours of play all I can say is that this is not your father's class D amplifier.  There is not one thing about its sound that reminds me of the class D gremlins that I do not like.  The low end filled in and now has deep impact, the midrange is the love child of a beautiful tube and clean hybrid amp - just gorgeous.  Highs are very clean and extended. Spatial cues are top notch. My system has had some damn good tube and solid state amps in it before and it has never sounded this good.  I am blown away with the quality of sound coming from class D amplification at this price point.

This 300 wpc amplifier is a real winner.....

Sorry but you were the one that jumped on timing3435 for presenting the bench tests link on this threads subject amp.  Why don’t you/we stay on topic? Thanks Andy

The rising measured distortion is due to the feedback used (very low feedback)......and has very little to do with the frequency response variations with load at 20K. The bottom line is you need to listen to something to know how REALLY low distortion it is........a single part (that is not measureable) can make more audible distortion than any single measurement. Everything makes a difference. Listen first.....then you will actually know something.

A comparison with the Peachtree, which apparently shares a lot of the innards, would have been instructive.

Switching frequency of only 400kHz - for a GaN amp? Where's George when we need him??? It's all in the implementation, not just GaN slapped on the name, but AGD seems to be way ahead in this game. If they can properly run Scintillas then I'm in. I wait with anticipation...

If they can properly run Scintillas

Not with this kind of rising distortion in the upper mids highs into 4ohms, as with the Scintillas, this distortion will be even worse from 300hz up . Doesn't matter what spin ricevs likes to put on it.
