Class D amps seem poised to take over. Then what?


I am certainly biased by my lifetime final amp being a Class D. But I know that after 30+ years of development, Class D seems to be on a high plain. I know there are now many, many companies focusing on Class D and, maybe, a good handful already as good as it gets. My Class D amp is as smooth and beautifully musical as a great tube amp and as punchy and detailed as a great SS amp. I am satisfied and done with my search. A class D amp has effectively taken me off the amp merry-go-round. It’s about time after 50 years. And, for me, this Class D is a milestone. Will all other classes of amps fade away?

It comes down to finding that great amplifier regardless of class. There are just ok class a, a/b and d amps just as there are great class a, a/b and d amps.

Those making claims that there are no great class d amps have not experienced the best that is out there. And i'm not talking about bargain amps or the most watts for the least amount of money. Most look at class d and are willing to give something up for the convience and money saving of class d. The class d i own allows me to have my cake and eat it too. I sold my Wavac 300b tube amp and Pass XA25 because they were collecting dust as my class d was superior to both to MY ears.

You used an SE 300b or a XA25 to drive a pair of Wilson WP 5.1’s!!!!
No wonder you think the Class-D AGD is the be all and end all to those 2 amps, which btw had no hope of driving the 5.1’s correctly, look at the combined impedance and -phase angle, the EPDR is around 1 to 1.5ohm in the bass very hard to drive. And like I say now also even for the AGD, but it’s better than what you had.

A demanding load, its impedance (fig.2) reaching a current-hungry 2.4 ohms in the upper bass, although this will be moderated by the relatively innocuous phase angle in the same region. The rise in impedance above 100Hz is due to the low-pass crossover; the low port tuning is revealed by the magnitude saddle between 20Hz and 40Hz.

Once again you know zero of what you say. I also do not desire to read your links. You fail to realize that at one time i owned a company that built speakers and have several US patents still in effect. Your one of those that wants to be a big fish in a small pond, it's somewhat sad that you feel the need for the attention.

Regarding speakers  Wilson's are not the only speakers that i own. I own Devore nines and super nines, Audio Note, Raidho, Magico, and Tekton. I also have Boulder amps that i'm keeping simply because i can only get half of what i paid new.

I come on here to provide to others my experience. Your combative with people and feel the need to be right. Your real world knowledge seems to be limited and comes from what you read or some review and not first hand experience. Some of your posts are quite comical and i detect the lack of knowledge.

And please no more paste and copy or boring links.

Everything has been proved, it is you that is the unknowledgeable one with no idea, and no will to learn, and with a fixation with what the AGD amp is cable doing and not doing.

Only because you know nothing of EPDR speaker loading, and are not even willing to try to understand what it is🤦‍♂️, I’ve tried, but you have https://ibb.co/6yVxb0Q 😉

But which tell them false stories of what the AGD is capable of doing into low EPDR bass loads of around 1 to 1.5ohms. That is why I post measurement proof to correct your falsehoods.
Every class of amplification and every amplifier itself, has advantages and disadvantages. Class A, AB, D, tube amps, single ended triode, etc. There are things that my current class D amplifier excels in that my previous First Watt F7, Almarro a318b, E.A.R. 890 and others did not and vice versa.

In the end, amplifiers are like women:
Which one do you want to live with on a day-to-day basis without annoying you to the point where you have to move on to something else?
Which one has so many positives that you are willing to put up with the negatives?

It’s the same thing.
