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?

My experience with SS, tube, and Class D amps over the years is consistent with what @atmasphere said about the nature of the various technologies over time and how that translates into good sound. I started with Class D amps over 10 years ago and it’s Class D all the way at this point for me. Tubes are fun but pretty much over that.

You will pay a premium in TCO for a good power guzzling Class A amp. No need these days IMHO. So many practical and affordable and great sounding Class Ds in various kinds of integrated devices.  Class D is where it’s at these days and in the future.  Pick some and listen for yourself. Also consider features and practicality if that matters to you.
