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

@spenav - much appreciated on the AGD experience - I will probably try and give the Tempo di Gani a listen

 

@twoleftears - appreciate the suggestion

 

Have a great day!

@tweak1  - thanks so much for your reply - your comparative experience is really helpful to me - at some point I am going to add a GaN to amp mix & owners of the LSA all seem very happy with the choice - Have a great day!
