An audio signal being a form of alternating current, it has positive and negative phases. The major reason to buy class ab over class d is that there are a lot more choices to buy below 300w/ch into 4ohms from vendors/manufacturers with a good reputation for support, longevity and dealer network and often at discounted prices. A class d amplifier is not a true digital device.

It should at least be in the 50 to 100 range. #4 · feb 24, 2016. On the other hand, class ab amplifiers are famous for better sound.

Moreover, they are a better version of all classes. Between a well designed class a/b amp (outlaw, aragon, perreaux, cinepro, rotel ab international) and a well designed class d amp (crown xls2500) i don't hear very much difference at all, or at least any differences i've heard could most likely be contributed to the comparison not being blind. I have no problem at all with g.

Classe sigma series amps and modern bel canto amps fall into this category. Class ab makes the input signal and output signal identical and every step of the way. Until the dawn of class d, class ab was by far the most prominent amp topology in bass amps.

So i feel class ab still seems to make the most sense. In short, it is making a larger identical signal. Class ab amp is a combination of class a and class b.

Devialet and linn fall into this category. Not only do they deliver better and enhanced sound, but they are also more energy efficient. You can think of them as operating together, class ab at low levels and class d at high levels.

If i come across a class d amp with a good damping factor, i’d be happy to try it out.
