Amplifier classifications (class A, A/B, H, D). Basic information on audio amplifiers. 

Glad it was helpful!

A lot has changed!

Thanks and welcome!

Thanks for your comment! Yes, the Carver PM series amps were excellent!

Thanks for your comment.

It is common for class a/b amps to still be in use, especially for subs.

@@stageleftaudio yes sir it's common specially if we have no choice,😂

Yes, the XLS1002 are efficient amps. Thanks for your comment.

For live sound, all the amplifiers (except for Class A) sound the same. In the many years of using all these amp classes, the biggest sound quality differences comes from the speakers.

The build quality is different than the original MA line. The production for their amplifiers is (I think) in Mexico as of a few years ago. Production used to be in the US. However, with computer connectivity to the amps, I think many manufactures are moving away from providing top-quality physical controls to manage their amps... when it can now be done through a computer. The chassis' on our amps seem rather solid (like the original MA-2400/3600 series). Can you describe the "soft" chassis? Does the chassis feel "lose"?

@@stageleftaudio Chassis doesn't feel loose but you could bend the tail section for the mounting brackets at the back with very little effort. The xti amps are cheaper but the build quality is much better. That's my only issue with those amps but they sound amazing

Ah ok, I know what you mean about the rear supports. We have that same issue with PDUs and rack drawers we use. It would be nice if Crown had kept their original design. Thanks for the follow up.

The MP2800 is a Class H.

Yes, as long as the speaker can handle the power.

Not bad!
