Actually difference between class A and AB?

If you're not one of the elitist that wont have anything but a class A amp, suggest you try a Magtech amp by Sanders Sound Systems. Wont cost you anything to try it, has a lifetime warranty, reasonable priced, delivers 500 watts per channel at 8 ohms and 900 watts at 4 ohms and and will deliver down to 1/4 ohm and finally runs absolutely cool. Has a 30 day no risk trial. What does one have to lose? Numerous reviews on this amp. See the Sanders Sound Systems website. No, I am not a dealer. I am just a very satisfied customer. IMHO an incredible amp.

everyone is talking about design difference. No one is talking about difference when listening. Can you hear the difference!???

no one ever talks about differences during actual use, because, there are none. As is the case with most 'issues' on this forum. But, since no one has mentioned hemorrhaging ears yet to support their argument, things are improving.

Rok2id, did you read the last paragraph of my post??? The only thing addressed in that paragraph is "difference when listening." That is the best I can explain it based on my experience owning three different Class A SS amps. To compare, the Class AB SS amps I have owned include McCormack DNA500, Cary 500MB, Herron M1, BAT VK500, McCormack DNA2 and Classe DR25.

Soundlock, why would a preference for Class A amplification make someone an "elitist?" I fail to understand why topics cannot be discussed on their merits, technical attributes, or on the basis of what folks hear in their systems and personal preference, without resorting to labeling.

Mitch2:

I have no problem with your post. I thought I was in support. In particular your question as to why everything is addressed as if we were in a lab doing tests and not actually listening to music.

Just to clarify, the Magtech is not a class A amp (you didn't state it was but kinda sounded like you did).
What one has to lose is the same thing one has to lose with just about every other piece of gear - Time, hassle, etc.
btw: The write up on the Magtech sounds a lot like the Sunfire amps by Bob Carver with the "Tracking Down Converter" power supplies, although there isn't enough info in the Magtech write-up to understand the technology used:
