Can you hear the difference between Class AB and D

Edit:
Here, an example. Bought for barely No money at all. Can I hear any difference between it and any of my other amplifiers? No..
Would I be able to hear differences with amp demanding speakers, with low sensitivity and the NAD vs my other amps? I do not know.I’ll probably play so loud that the neighbors will go crazy in that case.

Receiver NAD C 720BEE

I took some pictures of a NAD C 720BEE I bought yesterday. It lacks a remote control, but I will get one, a remote control that is.The model of remote control is NAD SR5. It says Zone 2 on my NAD. I suspect that there are different types of NAD SR5. Am I right about that? Anyone who knows…

How much is needed:

How much power does an amplifier need with this type of range of dynamic music

Feel free to use this calculator. Add sensitivity to the speaker and then tell which effect you have chosen and why. Weigh in that you want some headroom. http://www.mh-audio.nl/Calculators/REAP.html You can select music from this list. Or something else, but in that case tell us how you…

Edit:
Keep in mind that old vintage amps, where power is stated but with modern speakers, amplifiers with a fair amount of current may be required so they can handle low-ohm dipping speakers. However, NAD usually manages it (even older NAD amps).

By comparison, some other old amplifiers. Depends on the model and so on, so generalizing is not really possible. You can check the specified spec.

Edit 2:
Then it depends on how much demand you place on the amplifier. What you put in. Compressed music likes an amp to take care of. Sad for our ears, however.

No or wait what what are their respective power? When you start pushing amplifiers into clipping it can definitely be audible! But apart from that: noEdit:Here, an example.
