GaN amplifier from GaN themselves limited supply!!!

Why, on earth, did the mods remove this?

”@georgehifi

Designing an amp is a bit more involved than making a volume control…

Perhaps Ralph, who knows a thing or two about what an amp can sound like, is applying that knowledge to the D class amps - which are at the Beta stage (look at the link I posted) . And perhaps, building a world class amp, can take a minute to sort out, especially when you know what it should sound like.

But, feel free to keep on naysaying. Seems that is what you do best.”

Explain this to me please?

Yeah, my prior post got deleted as well. George gets very defensive whenever anyone questions anything about things he recommends here to the point where when even very knowledgeable and respected people here bring up valid points he feels the need to lash out at them and tries to discredit them by saying they have an ulterior profit or business-related motive (total bunk BTW). Oddly his unfounded claims against the reputations of these respected members are allowed to remain for some strange reason while posts questioning George’s motives or claims get deleted. Frankly I don’t get the double standard, but whatever. Still interesting to hear about amps made with these modules and exciting to see where the newer GaN, Purify, etc. technologies are taking the world of amplification.

@siox

Yeah, thats the very confusing part. Ralph has said nothing negative about the tech, just calling out application.

Meanwhile, George gets to throw his vitriol about.

Not cool...

And I am also curious about the new tech that is around the bend. Especially curious when a designer like Ralph does what could be argued as a complete 180 from OTL tubes to D class amps.

That is very interesting!

 

The first mentioned history of the new GaN output devices here on Audiogon

The new GaN transistors were reported here some 4-5years ago about how they will transform Class-D, especially the way Technics used them with the SE-R1 and it’s 1.5mhz switching speed instead of what everyone else uses around 500-600khz.

Here are the first post on Audiogon mentioning the new GaN transistors from "Alex Lidow" of EPC who was the inventor of the Mosfet, or one of them.

And the video he uses and measures the original older GaN by GaN evo board this thread is about the newer model.

And dht4me who has been in direct contact with Rick Reigel from GaN, says there is another "Reference Board" in the design stages.

This present unit bodes very well for the members here who can do very simple kit assembly themselves, basically mount the GaN board it in a box add some rca sockets and speaker terminals.

You got a killer Class-D GaN integrated amp with dac!! and variable feedback for well under $1500 that "could" blow any others here away, as dht4me reported when he demoed it to the LA audio crew and said,
"I have built 4 of these to date, the first was for me but as soon al local Las Vegas audiophiles heard it they were begging me to build them one."

Cheers George
