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?

@atmasphere besides your class D amps what others do you feel compete?

Thanks

I would suspect that a good salesman would not claim that others are close or better.

But I have also heard nothing but good about Ralph’s work.

There is Purifi and Benchmark that are generally well regarded amps in the Class-D space.

Or… personally… I would only be looking at those three for class-D HiFi amps.

FYI…Benchmark is not a class D amp. It’s a whole different animal.

@bigkidz

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?
