Why do I like Class AB better than Class A?

Hey guys, my source is MacMini running PureMusic, Wyred4Souns DAC 2, Aiff. I think I have solved the issue, I hadn't let her warm up enough, I thought 20 or so minutes was going to be sufficient but it was not, I give her 2 hours+ and is much much better. Though it still prefer AB with busy or complicated music like progressive metal and such. Thanks again

Class AB has more power,that is why you like it better.

I've owned the SA100 MkIII and the difference between Class A and Class AB isn't that huge though appreciable. Similarly I find the sound to be smoother, warmer, more organic and liquid with Class A. Music sounds leaner, sharper and more crisp in Class AB apart from having a slight edge in speed and transient attack - ideal for rock and music with lots of dynamic swings. With rock and metal, Class AB will be more ideal as music tends to sound slower and thicker in Class A due to the added warmth in the midrange.

Apart from the minute sound differences, Class A operation is also very inefficient. When I had the Plinius I usually listen in Class AB and find it to work well enough across a wide genre of music.

Ryder, great description of the Plinius, it is exactly how I feel it sounds between A and AB. If I may ask what did you move onto for amplification and why? Thanks in advance.

Barfbag, I moved on to the Naim as the speakers I had were mostly warm and smooth sounding designs, hence the match between the speakers and Plinius is too much of a good thing. Music lacks excitement and boogie factor and sounds lethargic in dynamic passages. Something just didn't sound right.

Having said that, I am sure the Plinius is an excellent amp that will sound great with speakers that are leaner, more neutral, open or forward. It's all about system synergy.

Enjoy~
