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.....

But there is no way there will ever be a class D amp that is truly state of the art until someone does every thing to the nth degree

This is correct, but even more important for Class-D to be able to do to over take the best linear amps, is that they cannot come close to doubling their wattage for each halving of impedance from 8ohm to 4ohm to 2ohm for those speakers that are very hard to drive eg: Wilson Alexia

And the even bigger problem to get rid of, is the phase shift in the audio band that the output filter creates to rid the output of most of the switching frequency noise https://ibb.co/Bs1tJ7d . And the only way to do this is to take it all up higher x 3 (switching frequency and filter) to 1.5mhz or more instead of 600khz.

ONLY then, could it be called to be better, than or equal to, the very best liner amplification.

por favor repite eso para siempre

Do you think any other thoughts? Do you dream of this at night?

No, only when a class D amp sounds as good as the best class A amp
will it be as good.....no matter what its power rating or switching frequency is.

Theory is theory.....reality is what is real.  Listening tests let us know what is real..
not rantings on a forum.



 It's funny reading the "arched back"😬 responses from those with a buck to make/loose in this game on threads that they push their own stuff that's got no technical cred whatsoever.
All I can say is that my bias against class D amps has evaporated after listening to the L SA Voyager.  I have had some awesome Class A, class A/B and tube amps in my systems.  I know good to excellent sound and I hear it with the Voyager - it is excellent.  Is it the best amp in the world? I doubt it.  Nevertheless, the amp is a superb clean, crystalline, spacious amp with great tone colors.  It doesn't break your back to pick up and move around either. 

Maybe it has trouble driving difficult loads but it has zero difficulty blissfully driving my modded Revel F208s.   There are tradeoffs with virtuly any purchase of stereo equipment.  I love and have several behemoth Class A amps that I can herniated my back from lifting, the best being my PassLabs X250.5 that is being modded at present.  I am very happy with the Voyager and have no longing for my other amps.

I had no idea class D could sound like this and I am sure it can be made to sound better.  I am no golden ear but, IMO, I have fairly good ears.  The Class D gallium nitride amps seem to be the real deal.

Very easy to drive, no bad -phase angle at those 4ohm dips, so yes Class-D friendly, 4 ohms is where they do their best work, but start to panic at 2ohms, especially if it’s accompanied with >-40 phase angle
