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?

I'm very, very happy with my VTV Purifi monoblocks (the 1ET400A, not the Eigentakt). They easily bested my Parasound A21+, and cost 33% less.

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

the AGD Audio Gran Vivace

the Nuprime Evolution One

the Technics SE-R1

the Theta Digital Prometheus

to name a few.

Take a listen when you get a chance an let us know what you think.

If I were looking for a new amp, I would be looking at Mola Mola monoblocks.

This is the only current amplifier that I have heard that left that feeling of that is special with me. Not sure what class it is but I know to me it was special! With the continuous increase in use of the internet there are very few brick and mortar stores left around here where top end equipment can be heard but this set of amplifier s I heard and really loved. 

 

 

Re comment above by atmasphere I can understand one of the reasons why my class A/B monoblocs sound so good - they use zero feedback and run very high into class A (400w each at idle). BAT VK655SE's.
