High end Class D amps?

As to OP's question,  the answer is yes, as of December of 2020. I am using one that qualifies.  How many are there, I do not know. This one is not "close", it's clearly superior to most class A and A/B I have used. Tonally superior to the tube amps I have used. Bonus is that price per Watt is low. Win, win, win...

I made a general statement, and I am not prepared to discuss at length. I have made a general observation, and that observation will be shown true or false over time as I build systems, but usually my first instincts have been correct.

Regarding comparison to the XA200.8, I have not done direct comparison yet, but I will. One of the XA200.8 has been back to Pass Labs for repair following my bone headed blowup wherein a metal plug of an IC was touching the output. Amazingly, the amp survived another four weeks before giving up the ghost. It's not back yet, so no chance to compare.
I attest to the sensational service of Pass Labs; no arguing, no bickering, no guilt trips, no plea for me to cover return shipping, which would have been expected, given I hurt the amp; just, "We'll arrange pick up, get it done and back to you." That is a big part of why they are world class!

For any kind of meaningful conclusions, several systems have to be made. This amp is very different from the XA-200.8, but so far to my ears, as legitimate. I think this may settle out like the two motorcycles I own; Yamaha Stryker and Yamaha FJ-09; two very different rides, but I love them equally. I am not of the school where there is only one form of excellence in amps and systems.  (If you are, great! So be it.) I have built too many rigs and used too many speakers, such that I do not wish to limit myself to one expression of fine audio.  :)  However, I do try to maintain a high standard for excellence across a variety of systems.

Especially since audiophiles love to jump to contusions, I usually withhold names of equipment before the time is right (publication). Sorry; sometimes you just have to wait.  

No, no, it's not the Tri-Art class D Amp, as lovely as that little number is.

Tsunami coming 

Prior to reviewing,  I owned two PS Audio HCA-2 units. Sold them not too long after because A and A/B kicked its ass. Now, it's reversed and class D is kicking ass on other classes of amps. It's going to be carnage. 

Atmosphere, you are bulls eye, on the money. Thank you for your contributions here! 

I can just imagine people trying to figure out your comment,What a class D amp potentially brings to the table is the ability to be neutral in a way that most solid state amps of traditional design cannot: they can be designed to lack brightness and harshness." Absolutely! I have used the amp on review on the hybrid PAP Treo15 Horn 1 and it is gloriously precisely as you describe. 

Our skeptics will doubt it. Their loss. 
 

I am VERY happy I did not finalize my position on class D and hold it inviolable over the past 15 years. I saw no reason to form an absolute resistance, as though it could not be developed over time. Participating in the process of assessment as it has developed has been fun, and now is nothing short of thrilling. 

Jim2 obviously read my intent of my posts wrong. I am always at 99.99% performance. It's the last .009%, the thousandths, that are tough to improve upon!  ;)

I don't do "wee hours" deals; industry members either call me within my time frame, or they don't reach me. I'm one of those unusual people who turn off the cell phone; I will not be a slave to technology. I have as first principle to avoid as much as possible the politics of the industry.

BTW, two manufacturers over the years attempted "shenanigans"; they were to check for technical errors, and they thought they could rewrite the article as PR piece. I rejected it, the reviews were published as written, and I vowed personally to never review their products again, a promise to self I have kept. 

Had to look up "Ray Donovan"; I do not watch much TV, and a cursory look tells me I could care less about such. I build and enjoy audio systems, often with a good book! Not much more relaxing to me to have a good read  while hearing beautiful music!  :) 

Cloak and dagger type things happening in the industry? Maybe with others; good for them! Let their life be "exciting"! I just do my thing.  :)
