Maybe feed forward compensation can help?
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?

Matter of taste between A, A/B or D. But like many have suggested, technology has allowed for Class D to push the limits on competing with many high end amps. However, I would choose class A any day. Just knowing the parts used inside along with the design and heft that goes with it. I would rather spend my money on that knowing the heft is whats behind my amp. And also not all companies build Class A amps so thats a thing of beauty along with the pure sound. I've own many amps in my time, you'll be hard pressed to find a build like a Luxman 590. IMO |
@petaluman As you might expect I have read Nelson's article before. He addresses the issue of poles in the amplifier caused by adding more stages of gain and how that adversely affects the use of feedback. I addressed that issue in my first post to this thread. A class D amp only has one stage of gain FWIW. Nelson does not address the solutions class D offers to the issues described in his article. |
