New Class D amplifiers

@kuribo, hope you answer my question directly this time without dodging it.

If you want dialog, be respectful.

On what basis do you find GaN lacking?

It’s all in the implementation. Current GaN devices are being touted as some magic improvement when in fact a class d amp is much more about how it is designed and built and less about the fets. Current state of the art class d uses regular fets, not GaN, and the reason is found in Bruno Putzey’s interview wherein he discusses this very topic. Google it.

Also, many of the GaN amps out now are using old class d amp designs which have no post filter feedback, resulting in load dependent frequency response. No modern class d state of the art amps have this fault. Again, use google to see why this is a potential issue. There are a few GaN amps on the market that are well designed- the Orchard Audio products have been well reviewed and have excellent performance. See the Audio Express article. I have no issue with GaN in general, just with amps that are jumping on the bandwagon with poorly performing designs or amps that are more about form than substance. As I said, there is no reason to spend $3000, $4000, $5000, or more on a class d amp to get state of the art performance. When you spend that sort of money, you are paying for cosmetics rather than performance. If that’s what is important to you, have at it.

Look who's talking 😆

And again you did not answer my question. Which tells me that you are talking about a product, about which you have no experience about. No doubt Atmasphere called you out on trolling. I cannot continue to waste my time with you anymore. If possible, try to add value to a discussion, in future. And remember your own statements from past about who cares about your opinion. Good luck.

Is there a way to block specific user posts on threads here?

You asked on what basis I find GaN amps lacking and said you were looking to learn. I gave you a thoughtful reply with leads on where to find further info to educate yourself. In reply, you insult. I expected as much. Information, like the GaN fet, is only as good as the implementation. If you were genuinely curious, you would have taken the time to actually do some homework and would have indeed found value in the reply. You got out what you put in and look intellectually lazy as well as dishonest in your intentions.

Whether or not I have heard the Atmos amp or any other has no bearing on what you or others may subjectively think about it after listening to it. I gave you cold, hard facts, when it seems what you want is for someone to tell you what you want to hear. Listen for yourself, no one else can tell you what you will prefer. If you understood the actual uselessness of other people’s subjective opinions you wouldn't be hitching your wagon to other’s subjective opinions and would see the ignorance of your question to me.

My issues are with poorly designed and implemented GaN amps, or expensive amps built to market to people who apparently care more about style than substance. As I said, these are my opinions based on actual objective data.
