Class A or Class D solid-state amplifiers (modern designs)


Hey guys.

 

Class A is supposedly superior. Something to do with a conduction angle of 360 degrees...so the entire signal gets processed in one go without crossover distortion.

But in terms of sound quality (subjective enjoyment) is there a benefit to Class A? Can class D provide the same level of enjoyment?

 

The dealer I’m talking to says that really nice Class A amplifiers are designed for "reference quality" meaning completely true to the real life performance.

 

Let’s compare and contrast. Which one is technically better?

 

In other words, could you have equal technical performance and quality in a Class D amp?

Specifically, we are referring to amps like the Merrill Audio Element 116

My previous post answers your question. Why do you want Ralph to advertise for other people? Would you go to GM and ask them who else makes good trucks?

@bigkidz

OK, so your amps at least to your ears are better. Fair enough. My question to you then is: what other amp(s) do you feel compare(s) favorably to your amps?

I have been using the AGD Audion mono for a few months and am still happy with it. Give them a try within your budget and you will be able assess for yourself. Most companies have a generous return policy. Good luck.

Thanks for the reply. I have one last question: have any of your creations been reviewed by a third party outsider with no horse in the race, like a magazine?  I am asking this because if you only listen to and compare your amps in your environment and with your specific associated equipment, that gives you a home court advantage. To my mother, I am the most handsome man on earth. While I accept your testimony, I would be interested in knowing what others think.
