LSA Voyager GAN Amplifier

So, what are you guys listening to this evening? I’m listening to vinyl. Right now - Nirvana - "Unplugged in New York". Sounds pretty darn good, and I’m not even really much of a Nirvana fan.

Peace be with you. And you. And you...

Pink Doughnuts.

how do you ever hope to design products that more than a few people will subjectively like?


 

He doesn't. He doesn't have the knowledge to design a class d amp. He just rides on the coat tails of others.

@ricevs , I try to lead you to water, but I cannot make you drink. I don't think you are reading my posts or attempting to understand them, you are just responding in anger. A careful read of my posts will show that I have never once called you names, though you are giving me plenty of reason to do it. I choose not to stoop to your level. Even when provided ample proof that your claims are false, you still make aggressive, inaccurate posts meant to do nothing but denigrate like this one below. You have tried to take this posts about the LSA amp and make it all about you and what you do. I researched the product the OP is using, asked a question to fill in a piece of information I did not have, then analyzed how the two would behave together, and interpreted that based on extensively researched, well understood, and not remotely controversial aspect of subjective preference testing and psycho-acoustic testing. I presented my analysis in detail for others to discuss, refute, agree with, etc.

How about you tell us what is going on with the OPs system?

Its just the facts, as I see it...and read it......and it makes you angry because you HAVE to be right.....so you lash out and call me names. Name calling is usually the last defense of the ego. You don’t need your ego. We are all ready beautiful. You don’t have to defend yourself. There is nothing to defend....the ego is an illusion.....created so we can have some fun. Don’t take it so seriously. Love you. Now I am reallly done.....he he. I will not reply to you again. Have a beautiful life.

BTW, the "off the shelf" modules you talk about were listened to and tweaked over a couple year period by various people in the high end community. Check out Mark Shifter’s comments on this (he was one of the main people).  They made it sound the way it does on purpose.....I think they did a very good job.  The measurements were secondary to the listening tests.  And that is just the way it is.  Believe it, or not.  he he...

Well that is interesting, considering that these are essentially variants on the GAn Systems Evaluation boards that Skip Taylor designed for GaN systems, but with some of the flaws fixed and now sold under his company name. Considering those came out about March 2020 and the LSA GaN was done in July 2020, that "couple years" comment is quite suspect.  It does not "sounds" any particular way. The distortion while not state of the art (except for IMD) is below audible levels, so that pretty much puts us at how the output impedance goes up at higher frequencies resulting in speaker dependent objective and subjective differences.

Mark Shifter also said this,

"We believe that GAN FET technology is the holy grail of switching amp design"

... which has about as much relevance to audio and amplifiers as saying "I like blue".

Since you don't appear to have anything relevant or concrete to add to this conversation @ricevs, I will say good bye.
