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.....

The output filter and the feedback system around it form the ability to see the load.....its a system.....load dependancy is because of the filter and the feedback. Yes, it would be nice if it looked better.......but does it make the sound bad? No. And what do you mean "distortion"?.....What distortion are you hearing because of the minor frequency rise or fall?  And even what distortion do you measure because of the minor rise or fall?

You need to understand that the switching noise filter/s gives you the fr vaiations. Where the load dependancey distortions here are comming from the amps output stage, at 4ohms 5khz 10khz 15khz have fast rising distortion after only 10watts!!! .

Thanks Andy

Andy...Why dont you list all your gear in your profile? I am sure we will all be in AWE of your near perfect measuring components.  Waiting for you to tell us that the Dac in an OPPO 205 is as good as the ones found in TOTL Esoteric/DCS/MSB like the rest of the penny pinching audiophiles on ASR do.

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.
