Wow. That is crazy. I hope to see how it performs if there is any second, third and so on harmonic. And if it is linear across the amplified the frequency range. Seeing forward to part two! :)
@Optimize since zero distortion circuit does not exist, there will be some distortion. Unfortunately, the lowest distortion for this design is around 10W output so the sweet spot of this amp way above my listening levels of around 1W. Otherwise is a perfect summer amp with almost zero dissipation.
thank you for your videos, love them. I've seen another video from you about the starkrimson gan module. Did You have any chances to compare them as build and sonically speaking? thanks
Thanks for the great feedback! I had to return the boards before I could do any listening tests. I thought I was going to get new boards to test but nothing yet.
Thanks, Eddie. That T-shirt and amp is cool. Can't wait to see it in action. Maybe the board needs to be that large to keep from needing heatsinks? Congrats on 5K when it gets here shortly!
Thanks Robert for that observation! I was thinking that too at first, but then it also doesn’t seem that there are large copper flooded areas to dissipate heat. It’s very impressive I think. I’ve found some eval cards are like this where it seems to have been made for probing, so most parts are on top. Then others are made to show how compact they can be.
10k in the bag, for sure, with these very interesting state of the art videos. Its a shame they didnot send a 600w ps to match the 600w 4ohm amp, but it came at a good price...
Thanks Greg! You are right - since it is rated continuous power in the amp, seems like it should have been for the PS right? It is hard to complain when it is free;) Actually - I need to offer my own spin on this for the DYI crowd...
@@KissAnalog Maybe you sure write a polite letter thankin Gan for the $900 amp and request the 600w ps explaining how someone had accidently incorrectly sent you the 400w by mistake :). Have a great day.
“It has standoffs so you can avoid damaging it” he says, throwing the board around and rubbing fingers across the components and circuitry :). Those GaNs are interesting, I’m going to have to do some investigation myself. Do you think they would be a useful substitution for a Mosfet on a DC load - expensive, but no heat sink and interesting to play with when not productising anything?
LOL. I think they would be great where they more efficient when switching, but if they are used in a more linear fashion they will dissipate power in Volts x Amps like any other FET and will not offer the better thermal benefit. Except for their better thermal interface.
The yellow plug looks like a digital input. I guess the big chip at the opposite side close to the digital inputs is the D/A converter und the big chip at the top side is the micro controller.
Yellow is the spdif digital input, in the back there is an asahi-kasei, the AKM, either DAC or ADC chip. I don't know if the amplification is digital or analog and weather both the analog and SPDIF input levels are controlled by the level pot. Where are the Gallium Nitride fets on the amp board?
@@KissAnalog whats the AKM chip number? I can't read it in the video. The folks at elegant audio solutions 'EAS' did a good job. They are a small outfit out of Austin TX.
Great question - thanks! Both the positive and negative amp outputs have essentially identical circuits. Both terminals are basically tied to a push pull set of transistors. So, there is not ground or reference as we might think of it. However, the positive and negative terminals are important to wire as such to keep the phasing correct. Does that make sense?
👍 great vid. Did I hear that correctly $900+ for 240 watts per Channel. That better blow away all the competition at the $2000 plus range chassis systems.
You are right - but that price is for an eval that they don't plan to build many of or at least I'm thinking...;) I want to design a board that others can build at much lower cost and be a kick butt system;)
Hey man! Loved watching this one. Really know your stuff and the passion comes through. Congrats on 5000! Onwards and upwards!
Thank you! I appreciate you! Hope to hear more from you soon - and I hope to kick more videos out on a faster bases. Got to get to 10 k right? ;)
@@KissAnalog you'll be there before you know it mate :D
Stay curious and don't burn yourself out!
Wow. That is crazy. I hope to see how it performs if there is any second, third and so on harmonic.
And if it is linear across the amplified the frequency range.

Thanks Optimize! I just shot the part two, so I hope to get it uploaded soon. Should be by Tuesday morning;) Thanks for your feedback!!

@RC No, no heatsink is needed on cool GaN devices.
Hi Eddie, I really liked your video was awesome, a lot of good information. I really appreciate you sharing your knowledge.
Glad it was helpful! I appreciate your support!

Great and important

@@KissAnalog thank you too
You have good explanation way
I like it

I see - so much better as the high/low switchers in a SMPS

Sent an email about this Eddie !! Good video sir !
Got it! Been with Family on a ski vacation;) I'll get back to you!
@@KissAnalog I didn't get the Ski invite :( must have gotten lost in the mail :P hope you had fun, good to catch up on phone this week !
Please explain the meaning of the bridge tied load. Is the negative speaker terminal a gnd or a real negative pole?

@@KissAnalog ok! So are there 4 GaN fets per channel, right?
Please make a video on high voltage class d amplifier gate driver
Ok soon. Thanks for the request - I appreciate you!
Thought it was James Hetfield talking on electronics... Not disappointed after all.
Diego Castro LOL Thank you Diego! I appreciate you!
