LSA Voyager GAN Amplifier

Looking at the V 350 under the hood pic, it appears one area to upgrade, that could improve the overall sound, is heavier gauge wire from the modules to the inputs

 

But the more attention you give to reacting and being in resistance....the more miserable you are.

Well, you know what to do.🙏

As I said to others before, this is just a strange thing to say, that you can see many mods to do to this to "take it to another level", just by looking at this picture. (it's just "snake oil" talk)

Happy Holiday

Just felt that as this point I needed to send along a few points.

Not here in any way to argue or attempt to interpret anything about the Voyager as said by others. I will however mention a few points as it relates to us. 

There were two of us involved from the very beginning of POC and Module Testing from the very beginning. That would be Doug Goldberg and myself beginning in 2015 (yes... you read that right)

Post these early tests which included some AMAZING higher power modules... my friends Peter Madnick, EJ Sarmento and later, Dr Viet Nguyen contributed to findings and feedback. This is especially true for EJ and Peter. We have all tested and participated in DIRECT FEEDBACK with the maker. I have known this incredible guy I've known for well over 30 years. 

There were several suggestions made during the dev process on the lower power version of this module. This one was the 200 watt version. Walter ultimately decided that he wanted to go with the Higher Power Version which did slow us a bit. 

There were many (read please MANY) revs of the original module. If memory serves - 5 in total, and a huge amount of man-hours testing and listening. I personally have probably near to 300 hours in test and listening to the 200 watt version and then over 100 more with the current module. 

The team that developed these modules and SMPS are some of the brightest super-power Engineers known (to me or otherwise). A real Dream Team. 

Lots of decisions were made along to way productizing The Voyager GaN 350.  I'm proud of the product, and I know our team is as well. This is a very special amplifier. Walter stuck to the program and our end users are reporting some fine results. 

Best wishes,

Mark

Please guys.....do not respond or reply to George. He will just say the same thing over and over again. He will fight, fight, fight you. It does not matter to him that he has no proof of his 1.5 meg switching superiority or necessity

Kettle, meet pot!

Ric the Tweaker who keeps saying the same bs over and over with no proof, is no different than that other class D dogmatist. At least George tries to offer some sort of rationale, but not Ric: "everything matters". He never includes the part about how most of his voodoo has never been proven to have any basis in fact or reality or the fact that human perception does indeed have limits. Oh, and there is also that pesky bit of reality he ignores called subjective opinion. All his tweaks make things "better". Better for his bank account, for sure, but do people honestly believe everyone has the same opinion/taste as to what is "better"? I am amazed at the people here who blindly drink the koolaid. A fool and his money...

Ricevs,
To quote you, "So, I did the AC mod (better wire, jack, less fusing, etc.)....now we are talking. It is not as warm but much clearer and faster and real sounding.....the micro harmonic info is not being covered by the excessive warmth. I am now more "moved" by the music."

This is an excellent summary of what I am saying and looking for.  Even though you later qualified your statement to mean that the Voyager is "warmer than the winter" this original quote says it all.  (Often in life, our first statement is how we really feel).  Live, unamplified music has the micro harmonic info that makes us cry.  All audio systems bury the micro info to some extent in the electronic warmth, which is nothing more than distortion from fuzz and mush.  Notice how you say that after your AC mod, the sound "is not as warm but much clearer and faster and real sounding."  YES!

Please guys.....do not respond or reply to George. He will just say the same thing over and over again. He will fight, fight, fight you. It does not matter to him that he has no proof of his 1.5 meg switching superiority or necessity.......he will just keep saying it over and over again and posting the same graph of phase shift over and over again. In all the years he has been pushing this idea.....not one single manufacturer has gone higher than 800K.....none.....many say it is actually a bad thing to do and causes to many problems.... to go any higher than 800K.

However, I think there is merit to pushing the switching frequency as high as possible....and I have said so several times. Three companies claim that raising the switching frequency to 7-800 K improved the sound (AGD, New Class D and New Prime (the first to do it)......so, there might be some benefit to going even higher if it can be done without drawbacks. Technics did it with their first $17K digital amp......and it is considered very good sounding. But to think it is the ONLY THING NEEDED to get "state of the art sound" without any proof whatsoever and keep stating it over and over as FACT is really just the rantings of a delusional soul trying his hardest to prove his worth. To bad he does not see how beautiful he is....then he could stop all his constant rantings.....saying the same thing over and over while he pounds his chest and calls people names......Growing up is not easy......we all have self esteem issues....if we did not....we would not be on the earth. This is our playground.....this is our SCHOOL. We have come to learn....to grow....and to find our true nature......the bliss that we inherently are.

So, when George spouts off.....just let it be....otherwise its a spiral of wasted energy for all. I hold George in the light....just bless him....like you can when a crazy speeding car or motorcycle races past you......just say "bless you and be safe".

George is blessing us by being how he is. He is a test from spirit. It is the same with the entire universe. Everything will keep pressing your button until you realize it is all perfect....RIGHT HERE AND RIGHT NOW. You do not have much control over the circumstances of life.....but you have complete control of your response. If you hold life as sacred and everything as sacred then you realize that the button pusher is divine. You welcome it. However, there will be no button to push when you give up YOUR desire and attitude that keeps the button in place. You will eventually react less and less and finally someone will kick the button like heck....and you will just grin.....thinking.....Oh yeah I saw that film on tv years ago.....don’t need to watch that again. We create each other to grow. So, we created George for our entertainment and growth. Blessed is he. But the more attention you give to reacting and being in resistance....the more miserable you are. So, pay more attention to what brings you joy and less to what you resist. When you stop fighting and resisting and trying to be right.....then your world will be bliss (battles over). "Excuse me while I kiss the sky" Have a great week.

Mine is scheduled to be delivered on Tuesday.  It sounds like you are offering a good deal with the PC for anyone who is in the market. 

That was me selling it. It’s only because I feel my Parasound integrates into my 5.1 class A/B system better. The voyager sounded fine in that scenario, but the Parasound was better. On its own in a 2.0 or 2.1 system, the Voyager is excellent all around. If I were using it for only 2 channel system, I would never have put it up for sale.

Interesting to see one week old LSA Gan 350 for sale on Audio Mart already.  Did not comment on why they were selling

The LSA Voyager 350 that @ricevs is modding for me can definitely drive my difficult to drive Thiel  CS3.7's. Now I did not crank the music to very loud levels but other amps were lacking on these speakers at the moderate levels I listen too.

Please if you don’t know what it means by now, don’t keep asking.
This explain it all, https://ibb.co/Bs1tJ7d at 600khz
Even at Technics at 1.5mhz there is still some small amount of phase shift in the audio band, so at 800k it's still there "almost" as bad as Icepowers 600k

George,
You keep spouting the technical merits of a 1.5MHz switching frequency as a requirement to excellent SQ. You should listen to an Audion to realize what a lowly 400kHz can do.
I would bet that if you listened to the gen2 Audion at 800kHz you'd forget the 1.5Mhz thing - if you had any sense.

Maybe it has trouble driving difficult loads but it has zero difficulty blissfully driving my modded Revel F208s

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

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.

 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.

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.

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.

Cheers George

Actually, the Voyager and Peachtree are using off the shelf modules (the amp modules and power supply) that do not need a separate input stage. They are both plug and play boxes. There will be more companies following suit. LSA and Peachtree had very little to do with the development of these modules......they are end users.

The main reason GaN amps have taken so long to be available is.......you had to design your own amp board, like Merrill, Orchard, AGD and Class D audio did. There were no companies making and selling GaN based modules. Now there is. And these modules are really good!.....even without mods.

Here is the main problem with Class D.......it is complex
The input buffer on a class D amp has as much circuitry in it as a Coda 8 amp. And that is just the first input buffer. And these input buffers are usually $1 op amps.....not discrete stages.....this is true for AGD, Orchard, LSA, Peachtree, and Class D audio. I don’t know what is in the Merrill as they will not allow anyone to remove the cover.
So, you have an input stage that is not as pure as the whole Coda amp....then you add another op amp......and then maybe more and then the driver and then the output devices and then the coil on the output.....Wow! it is amazing that they sound good at all!!! And they do. Miracles do happen.

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.....that means no op amps.....that means every part picked for sound.....this is what Boulder and Coda and Gryphon, etc. do. When you see these big companies make a class D amp.....the game will be over. Class A will truly be boat anchors...

So, is the new $3000 about to be released GaN amp from Wyred for Sound all built with discrete transistors and tweaked to the max? How about the new Mytek GaN amps at $6K and $20K? Will we see state of the art class D soon?

So, if the AGD amp has $1 op amps on its front end....how come it sounds so good? Because you have a listener/tweaker at its helm. He spent hundreds of hours tweaking the Mk II version. Please read the review on Enjoy the Music about it.

http://www.enjoythemusic.com/magazine/equipment/0421/AGD_The_Audion_MkII_Review.htm

However, as long as he keeps those $1 op amps in there....it will never be state of the art. No doubt he is tinkering away as I speak.

All the new GaN amps are great for the money.....and modded they can be taken to new heights......but do not expect state of the art.....not yet.....soon....however, it probably won’t be cheap if everything is done to the nth degree........I would guess above $10K......and at first, maybe way out there.

So, now you know.

Have a great every moment......you deserve it.  You are beautiful.

@rajugsw


If the LAS Voyager was an off the shelf module that was 'merely' in need of an input, I and presumably many others would not have been waiting 2 full years from it's initial intorduction

Ricevs,
My Rouge is pretty substantial. 23 lbs, decent casework.  Francesco wrote me and asked whether I wanted white or blue LED on lights, details about engraving of the round dial on the front.  He treated me as if I were ordering an expensive D'ag amp.  Rouge looks like a higher class company than the DIY'ers.  They have many different products using Pascal, Hypex, Anaview modules as well as IceEdge.  Thanks for recommending Rouge.

Your clueless when it comes to REMASTERED CD’s. The Original CD Pressings in the 1980’s are VASTLY Superior in most cases compared to your beloved "remastered" Crapola nowadays that is compressed to death/Brickwalled/Loudness wars...whatever you want to call it.

+1

For those in denial look at this (red bad squashed to death) compressed
They only got together once and made the one album master, but it was re-released many times but got gradually squashed to death with compression the newer the release got. Just for listening in car/streaming/download/ipod and background music

rajugsw,
Sorry you got up on the wrong side of the bed this morning. You sound like someone in need of love. I love you.....you are beautiful. The whole world loves you. Give yourself a hug.

Orchard makes a GaN module (that he tried to sell to VTV) and so does the company that makes the ones for Peachtree and LSA. Who is to say which module is better? The Orchard amp is not even released yet. And who cares how old someone is that designed it? Then there is the $3K Wyred for Sound amp coming soon. So, there will soon be 4 GaN amps in the same price range......then there are mods to each one.....so that makes 8 different possibilities. Are you going to be the first to have all 8 of them in your room at the same time and burn them all in for 200 hours and A/B them all and tell us which one you like best? The GaN wars are just starting. We will have more and more of them.

So, stop whining and enjoy what you have. Your amp may be better than "theirs", or it may be different, or worse. Sorry it means so much to you. FYI...The Orchard amp uses a cheap chassis from Italy.....I know, I used that one for my EVS1200 amp. If you press on the top it goes down. If you press on the back panel it moves in (I had to do mods to it to not have it do that). Not well designed. Do you think the Orchard tree logo looks great on it? The power supply Orchard uses is a stock power supply from Hypex. Sorry to burst your bubble. I don’t care which one is best.....I mod them all.

Enjoy this moment.....it is the only moment that is this moment.
Breath......everything is fine.....just the way it is.
Love yourself and everyone.
Dance and sing a joyful song.

Your clueless when it comes to REMASTERED CD's. The Original CD Pressings in the 1980's are VASTLY Superior in most cases compared to your beloved "remastered" Crapola nowadays that is compressed to death/Brickwalled/Loudness wars...whatever you want to call it.  Maybe yours sound like garbage because it coincides with the level of gear your using.

1. LSA Voyager 350 $3000
2. Wyred for Sound amp $3000 not yet released
3. Peachtree 400 amp $3000
4. Orchard Audio amp $2500 about to ship

What’s with all the love for the LSA stuff & Peachtree stuff (pretty looking boxes) ? I’m sure it sounds pretty good but aren’t they just pre manufactured GaN Amplifier modules with a custom input stage. Kinda like what PS Audio does with the ICE Amplifiers with both FET (M700) and Tubes (M1200)

While I’m a self proclaimed Orchard Audio Ultra Fanboy, I see no recent activity over on the Unofficial page I setup

https://forum.audiogon.com/discussions/unofficial-orchard-audio-starkrimson-ultra-amplifier-owners

What gives ? Are you all a bunch of "Old Guy Geezer Audiophiles" that don’t takes these younger (under 50/under 40) Audio Engineers (ok...EE’s) seriously and just go buy whatever buzzword/company name is the flavor of the month ?

I seriously think it’s time Audiophiles give more credit and exposure to what’s happening now in the industry and stop reminiscing about the good ’ole days" of Tubes and Transistors.

No argument that the GaN stuff ain’t cheap to build and market. But as I read that people are seriously swapping out their dearly beloved Tubes & Transistors for these devices manufactured by Infineon & GaN Systems. It’s very reminiscent of when people got rid of their LP’s and replaced their collections with CD’s. While that was a mistake (myself included) in the 1980’s/1990’s. Technology’s such as DSD and Hi Bitrate PCM along with advances in CD remastering and come along since those harsh sounding CD’s of the 1980’s.

Hell, I’ve got a BATVK50-SE in front of Leo’s loaner Ultra Amplifier and it sounds fantastic !

The stock Voyager is very good however I had a similar feeling.

I was not moved

The Voyager is not as good being colored as my CODA and KRELL, which both sound great. Going the other way to make it sound super clear and naked would be a great choice. 

OH my!  Did a simple mod that made it warmer and more detailed.  Then did another tweak to the system that was needed.....OMG this amp is good!  I will wait till I have done several more mods to comment again.  To busy crying.

I should not have said.....very warm.....it is not very warm.....just warmer than winter.  Music has natural warmth.....everything depends on everything else for synergy.  It is harmonic richness that makes me cry.....not warmth per say.  However, you need the right amount of warmth and all the harmonic richness (that comes from transparency, low noise and low distortion).  What is the right amount of warmth?....no one knows.

Less electronic warmth is not always associated with faster and clearer....sometimes it is just a lack of warmth.  It is not black and white like you always describe.  Some warmth is added fuzz.....some is real.

Please do not tell me what I have done or not done.....how would you know?  You are wrong about this.  I have listened to every single thing I have ever done.  I know what each mod does.  This is why it takes me so long to do a product.  I keep saying to myself...."just do all things that have always made a difference and be done"......but instead, I listen to each mod one at a time.....and almost always I get the same result as before.....but not always.....and since there is synergy.......there needs to be careful listening tests done.

Ricevs,
Thanks for your analysis of just the AC mod, which in your words, changes the stock V to be "not as warm but much clearer and faster and real sounding." Apparently you found the stock V "very warm."  From reading my posts, you know that I believe that less electronic warmth is associated with being clearer and faster, so you have confirmed my experience on this matter.

This is a great opportunity for you to write down your findings with each mod you do.  You have never done this, but previously you have done all the mods and reported the final results.  By changing a single variable at a time, this gives you a better understanding of everything you do, and reporting what you learn is valuable for everybody.

Thanks.

NICE! ricevs - keep us posted

OK......a little tid bit on the Voyager sound.  Finally got to listening to the stock fully burned in Voyager (sitting on Mad Scientist footers....not the best ones, however) and the sound is very, very good.  Lots of information.  However, I was not moved.....even though it is very warm and big sounding.  Last time I played the Luiz Bonfa CD I was crying (using the modded Purifi amp here).  So, I did the AC mod (better wire, jack, less fusing, etc.)....now we are talking.  It is not as warm but much clearer and faster and real sounding.....the micro harmonic info is not being covered by the excessive warmth.  I am now more "moved" by the music.  However, some could like the amp stock better....even with its coloration.  I can see that.  Me, I want the naked truth.  However, there is more to be done and I hope it brings out even more harmonic info and delicacy.....without edging into the "hard sound" category.....something I do not like.  The tweaking has just begun....next up is the output wiring and binding post bypass system.

" Damn, what happened to just figuring out how something sounds, how does it sound relative to other kit, and what are the system synergies. I mean, some of the tussles in this thread just blow my mind."

Amen to that - when I started following the thread (with real interest in the product), I had to look to see that it was really about the LSA amp vs. the now deleted EVS 1200 thread (and probably most of the other Class D threads).  Some things just don't change.  Just wanted to let everyone know who is positively contributing to the thread I greatly appreciate the information from real hands on experience.

Damn, what happened to just figuring out how something sounds, how does it sound relative to other kit, and what are the system synergies.  I mean, some of the tussles in this thread just blow my mind. 

Trouble is.....no one cares....and he keeps ranting and disagreeing.....saying the same thing over and over (as we all do)....disturbing the peace. So, if you keep quiet.....we can hear our heart flutter its soft joy.  We can see a post by him and just move on....stay in happiness....don't get caught in the downer drama......it will just fade away.  The drama we want is upper drama.....the good news.  Fighting and "heavy duty" points of view are part of the downer drama.  Does not mean you cannot discuss things and have a different point of view......but you can learn to stay in your heart and always post something that you know will be uplifting for all......not just a point of view......listen to your heart.

I have finally (boy I am dense some times) learned he will never hear what I have to say....so, there is no sense responding. I will correct something he says that is way, way off (but only once)......but there is no sense going over the same thing with him over and over and over again

@ricevs I've been at the same conclusion for a long time. I don't make the responses for his benefit, I do it so others reading this stuff at least have a different viewpoint rather than obvious misinformation.

In denial is the only phrase that comes to mind.
I find it very sad that the bothers in arms, have never heard the saying "Krell Like Bass" in audio, quite is bazaar, and that they think it wrong!!!

Interesting Darko review of the Peachtree GaN 400, finding it SLIGHTLY superior in HF detail to the Mytek Brooklyn Amp original version, which I find excellent.  The Mytek is quite neutral from my 2 year experience with it.  Darko's comments are consistent with the glowing reports from posters here on the Peachtree.  The Peachtree is probably very close to the Voyager.

Atmasphere,
I used to respond to George.....now, I have finally (boy I am dense some times) learned he will never hear what I have to say....so, there is no sense responding.  I will correct something he says that is way, way off (but only once)......but there is no sense going over the same thing with him over and over and over again....which is what I see you doing with him on thread after thread.  Whatever he says is not going to change the course of anyone's purchase or happiness nor change the course for humanity.  Anyone with a brain can see how little or how much George actually knows (based on his direct experience with the items/points of view being talked about). 

It is best to just leave him be.  If he has no one that is "reacting" to his posts then they will just die on their own......no problem for anyone.   BUT, if you keep responding to him (trying to FIX his words) then this nonsense will go on forever.  Peace is realizing that the world is perfect....just as it is.....including with whatever George spouts.  The deepest peace comes from the experience of being loved every second by the entire universe.....and that it has always been this way......and always will be this way.......no matter what the "circumstances" seem to indicate.  I wish you all the deepest peace.  For it is our "true nature"......our truth.  

Shouldn’t bass be like the music in which it exists rather than a certain brand of amplifier??

Yes, it’s obvious from that answer/question, you have not sat in a jazz venue when the unamplified drum kit is being severely belted.
It’s closest in audio as I said (Krell like bass) and similar amps to it, like Gryphon etc etc etc and defiantly not OTL and most tubes with the majority of hard to drive hi-end lower impedance speakers.

Your response does not address the question (which by definition makes it a Strawman logical fallacy). And not knowing me, you'd be hard pressed to know what I've done and what I've not done. But FWIW, I play string bass and have played in jazz bands. Sheesh. I suspect you've no idea that your response here was simply so much rubbish.

You are right about OTLs except for the larger ones, which have no troubles playing lower impedances. But the ability to play a low impedance speaker is not the same as saying the amp has excellent bass.


If you're into bass, you want unmeasurable square wave tilt at 20Hz (which is something our OTLs do). If you know what that means you also know that most tube amps can't do that. Getting good bass isn't about driving low impedance so much as it is making sure that the amp has the LF bandwidth, that its low frequency bandwidth does not exceed the timing constants in the power supplies and otherwise has low distortion in the bass region. Its not about output impedance, since an amp with higher output impedance will simply have to be used with a higher impedance speaker, and that speaker can then demonstrate that the amp does indeed have 'good bass'. I do this all the time at audio shows; for a long time we had the Atma-Sphere Bass of the Year list on our website, which was a list of recordings that shook the walls very nicely.


In solid state amps that are direct coupled, since the 1970s they have had enough feedback at 100Hz that they have no problems playing good bass. Once you have that feedback several things occur. The first is that the amp can reject power supply noise as the feedback will correct for that. The second is that the distortion at 100Hz will be low (we've been seeing that for decades). At this point the only real concern is making sure that the power supplies don't sag under heavy demand and there are plenty of high end audio solid state amps that fit that bill. The feedback thing is the key here; if the amp employs it and the power supply does not sag, it will have 'Krell like bass' since the Krell has sufficient feedback at 100Hz and otherwise has good supplies. So it then follows that if it has **more** bass then its the result of a coloration and in a nutshell, that's not happening with a Krell at that frequency.


The differences you hear in solid state amps, as long as the power supplies are not an issue (and this includes class D) are going to be in the midrange and highs. Admittedly, you'll hear some class D amps that really can't do the bass right, but you'll also find in those amps that they have power supply problems (which I excluded via the caveat above). Now you might be able to get a slight improvement in the bass by improving speaker connections and other minor tweaks but that has nothing to do with the brand if those tweaks are applied across the board.

Like I said either under a rock or too much OTL listening, with most hard to drive hi-end lower impedance speakers.

Shouldn’t bass be like the music in which it exists rather than a certain brand of amplifier??

You never heard anyone use the saying "Krell like bass"

Nope. I hear about natural bass a lot. Shouldn't bass be like the music in which it exists rather than a certain brand of amplifier??

You never heard anyone use the saying "Krell like bass"

It's sad then, you’ve either been hiding under a rock, or don’t get out much.

https://www.google.com/search?q=%22Krell+like+bass%22&oq=%22Krell+like+bass%22&aqs=chrome..6...

Every one knows big Krell’s bass is their forte.

I didn't know that, which seems to belie this statement. Other amps are known for their bass too- does that put them in the same category??

Thanks George

   

Is there any word of GaN-based amplifiers hitting the pro-audio market

"Right now, the company is seeing a growing demand for smart and battery powered speakers, multi-channel automotive and high-end home audio systems, and is also targeting traditional home theatre and professional audio markets, including stadiums. And according to Reigel, feedback from reviewers in the audio industry, so far, is good."

https://compoundsemiconductor.net/article/111521/GaN_Systems_All_Eyes_On_Audio_Amplifiers

Looks like it's coming, they're always a bit slower to pickup on the newer technologies, took them an age before they adopted Mosfets.

Interesting thread, thanks for sharing your thoughts.  Is there any word of GaN-based amplifiers hitting the pro-audio market (Crown, RAM, Powersoft), or even musical instrument amps?  Assuming tradeoffs in sound quality with increased power capability, are current GaN modules scalable to achieve 1,000-10,000W+ for pro-audio use?

Every one knows big Krell’s bass is their forte.


Take a chill pill, your still       off over the GaN by GaN Class-D thread which all sold out and I pulled.

Pays to look a little harder, or you only see what you want to see

" Larger quantity of bass is always associated with lower quality and accuracy, as shown by the Krell."

What exactly is being said here? Its possible I misinterpreted it and if that's the case my prior statement would be false. FWIW I've not heard excess bass from any system I've heard with Krell amps. As solid state amps go, if anything I'd say they are a bit dark on top compared to the brightness of many solid state amps. And that's not a bad thing- most solid state amps are bright due to distortion.


**If** you can change a fuse in a Krell and the bass is different, I think you'll also find that the mids and highs are different too.
