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?

Hi - has anyone here with experience with Class D amps had a chance to listen to the new generation of GaN amps? Any worth a listen other than the pricier implementations? Thanks! Have a great day

@spenav 

Thanks! Those look like a lot of fun

I’m running a tube pre into a pretty conventional SS Class A/B amp, and think it would be fun to have a few amps around with different “characters”

Let me know if you give any of these GaN amps a listen - would be curious as to thoughts vs “conventional” Class D, to the extent discernible…

May add a Benchmark AHB2 in the meantime…always so tempting

This is supposed to be a little bit better than the monoblocks.

If you're interested in investigating quality implementations of GaN at lower cost, this is where I would start (rather than the LSA Voyager or the Peachtree Gan 400).

I have been using the AGD Audion mono for a few months and am still happy with it. Give them a try within your budget and you will be able assess for yourself. Most companies have a generous return policy. Good luck.
