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 was never able to hear the AGD Gran Vivace but the Audions were superb. I now have custom modded Altec Lansing 1570B mono blocks.

I'm upset because I just found out you can't run a Class D amp in pure Class A

Class D fan boys, say what you want about class A it’s still the benchmark. Read the interviews with Bruno and the boys and you will find out that unlike what Nelson does which is small adjustments they had to actually add and remove components to their modules to get them to sound so transparent to your ears. I would rather have someone making tweaks then redesigning boards. But the rubes will buy what the rubes will buy, cheap rules. check those power ratings, if they are higher than what your speakers are rated for you are in for a heap of trouble. No one needs 725 W or 1225 W unless you are a band in a concert venue
