Class A amps


I've read a few articles on class A amps but still don't have a good understanding of how it affects sound quality. I've even seen amps which can be swithced into class A mode or AB. Does anyone have experience with this type of unit? Does class A have a true audible advantage or can it be detected only by test instruments? If it is audible, in what resepects? Thanks, Rick M.

Lets be perfectly honest here folks, who actually listens to music on output levels of 50 watt and above, certainly not many of us with an interest in sound quality IMO. At this level you probably listen to more room distortion than audio reproduction distortion.
 
Most modern design transistor Class-A amps run at this class at lower output levels thus providing good source reproduction without any crossover distortion. Once you ramp up the volume the circuits are design to operate in AB mode.

For sure your input source and speakers can make a huge difference in sound quality, as can the positioning of your equipment.

I guess the thing with sound quality (audible not oscilloscope) is its very subjective, your friends and neighbours will always think there sound system sounds better than yours. My wife claims she makes the best lasagne ever, I've tasted better !!!
