Class D


Been thinking of trying a D amp to reduce clutter. Most that I see are not rated at 2 ohms.  My PSB Stratus gold's will drop to 3 ohms or lower at some frequencies. So my question is will these types of amps handle this impedance ?
Thanks in advance. Chris

Received confirmation yesterday that I'm right. I was perhaps 90% confident prior. I'm about 99% sure now. 

Tsunami coming! 

 
Thanks for the reminder! I need to see about potential fuse change in this new Class D amp! Total fun!  :) 
Ah, well, I'm starting to have some perspective here. I was unaware - never bothered to care or look - to discover georgehifi is an industry member who sells his own attenuator. Well, NO WONDER there are issues here, and ferocious debates in regard to class D! 

georgehifi, please accept my apology; I thought you were a curmudgeon with a bad attitude toward the industry. You are free, of course, to argue, defend, your product as you see fit.  :) 

I'll recuse myself at this time on further comment on class D in general as compared to other genres of amps. I will have plenty to say about that in the article. I most definitely am checking into an aftermarket fuse for this class D on review. Already spoke with the manufacturer to get info on the value of fuse to acquire.  :) 


I do not think I have ever been more excited by the prospects of amplification in the industry than now. There are wonderful things coming for the hobbyist! There is no reason that most participants here cannot all have fundamentally superior sound in the next 2-3 years, due to developments in amps.   :) 




georgehifi  has been talking up GaN for a long time. 

If I am not mistaken, the new Technics integrated uses GaN chips. 

Interesting assertion, Mike. I have concluded much the same with a different class D! 

Now, which is superior? My class D, or yours? I did not hear anything from the Gan amps at AXPONA that would make me think they are superior to the one I am using. You are hurting your reputation with such an open-ended assertion. Imo, the problem isn't so much what you said in regard to other classes of amps; it's what you asserted in regard to other class D amps. Imo, unsupportable and a mistake.  :(  It's not too late to walk it back.  

In regards to the emergence of the superiority of class D, however, you are correct. With amps like this, it's a new era. 
ricevs, I'm just ebullient due to the performance. Forgive me, I won't talk about it anymore.  ;)   The article should be coming sometime in the first quarter of 2021. Still some important system building to do for an attempt at ultimate build, performance, etc. 

No, it's not Exogal. However, I am using the Exogal Comet DAC with it a lot, with spectacular results. 
georgehifi, perhaps. Comparison would tell. My comment was not meant to be a definitive conclusion, btw. I think that was clear, and that only head to head comparison would reveal distinctions.
