Agree with Kijanki, I have a class D amplifier that retired my favorite class A/B amplifier of over 20 years (recently modified about 2 years ago). I find my class D amplifier to be superior in terms of detail, spatial placement, sound stage and especially dynamics. Clearly from my listening position I could always hear my class A/B when music was not playing...doesn't happen with my class D.
Class D Technology
So I get the obvious strengths of Class D. Efficiency, power output & running cool which allows for small form factors. I also understand the weaknesses somewhat. 1. Non-linear & lots of distortion that needs to be cleaned up with an output filter.
So my question is, if it weren't for efficiency & power, would there be any reason to own a Class D amp? Do they beat Class A in any other categories that count for sound quality?

This may be of interest to aficionados of Class D. http://www.psaudio.com/stellar-m700-mono-amplifier/ |
I'm not sure what this "class A input stage" is. Input stages are almost always class A (would be stupid not to), but class D amp is pretty much one stage - a modulator + output transistors. Any additional input stage is not advantageous to class D amps. What they call "Analog Cell" is just class A Mosfet input stage very common in many class A or AB amps. It sounds like a lot of hot air (for class D). |
