New Class D amplifiers

I think there are a lot of people that expect their equipment to last 20, 30 or more years. I have Rogers LS3/5A, Series 20 M22(Pioneer) from the 70's,  Acoustat 3 and Linn Sondek LP12 from the early 80's, Sound Dynamics 300TI from the 2000's. All work great.

Look at people using original Quads, Altec A7 VOT, Western Electric and many other brands. Parents taught me it was cheaper to buy good stuff. Hope my Orchard Audio Starkrimson Stereo Ultra and PSAudio S300 last many years. Just because something better comes out years later doesn't mean, older equipment quit being enjoyable. 

Thanks,

I have taken issue with products that, in my opinion, offer less performance at far greater price, than class d amps available from numerous other sources. 

You have yet not responded to my question. Have you done a comparison with a Purifi amp vs Atmosphere GaN. On what basis do you find GaN lacking? I am trying to understand that. Because, I also have to understand which tech I should go with, if at some point I want to decide to go Class D route. So hopefully you will have something for me to look into. 

BTW, that distorted interpretation came probably because you did not come across as trying to learn or ask. You sounded more like confronting. And your past posts have all been negative about GaN. So don't blame me for the messages you are sending. A few posts above another poster also hinted the same. Guess you didn't catch that.

Customers are also wanting to know that someone stands behind their purchase, and that sadly too is lacking with a lot of inexpensive options.

I haven’t heard or read of any issues with customer service from the many US and European sellers of class d amps using Hypex or Purifi modules. Do you have actual evidence of poor customer service you can share from any of the main stream amp providers?

From the way you consistently single us out, its pretty clear that this has nothing to do with price since there are so many more class D products that are more expensive. For some reason, this seems personal for you for reasons unclear to me.

I didn’t bring up your product here, you entered the discussion after I commented that there is no need to spend $5000 on a class d amp when there are better performing amps available for a fraction of that. I didn’t mention your amp by name. You jumped in and offered a justification for the high price.

And no, I have not singled you out, I made a general comment. I would respond the same way to any product here that has a performance not scaled to the price. I appreciate substance over form.

What you don’t seem to get, despite this being told to you a number of times when you’ve chosen to troll threads like this, is you’ve failed to identify the market. For example, you don’t seem to understand who our competition is.

I have chosen to troll this thread? No, I made a general statement that you decided to challenge. I simply responded.

But, ok, I have failed to identify the market you are attempting to serve. Let’s say then it must be that segment of the market where high prices are a feature, not a bug, and where "value" isn’t a consideration. That’s fine and honest. No need to justify your price here, I get it.

 

@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.
