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?

HAving owned MANY class D amps over the years, and especially in the last 4, the LSA Voyager 350 GaN amp is fantastic and a uber bargain MSRP $3000, but often on sale

Every time, and I mean every time, I put my Musical Fidelity A1-2008 Class A SS amp back in the system (replacing either a QUAD 909 or Transcendent Sound T8-LN OTL tube amp) I listen for about 10 minutes and then say "holy crap!" I forgot how incredible this sounds!

Pretty amazing when a solid state amp can equal or even in some areas even best t a high end OTL Tube amp.
