Hi Keith I am a newbie to Emotiva forum and also a recent customer. My recent purchase was two XPA1's for my B&W804S speakers. They are great amps and I appreciate the extra headroom I am getting with these amps than what I had with my previous setup.
My question is this, can you explain Class A mode as it refers to the XPA1? Also would I benefit from using Class A mode STRICTLY or
should I just be using the A-B setting.
I want to get the most from these XPA's of course without doing any harm to my speakers.
Thanks, Frank

Class A means that the amplifiers run in their "purest" form up to 60 Watts of power. If more than 60 Watts are needed the amps automatically and silently shift into A/B and then back again to Class A for likely the majority of your listening. If you put them in Class A/B mode straight away you will not get any of the added Class A performance or effect. I say effect because some people really like Class A (I among them) whereas others cannot hear that much of a difference between Class A and a well designed A/B amplifier. You just happen to have both, so leaving the switch in Class A mode ensures you'll experience both features and thus getting the most out of your investment. Enjoy! |

Just be sure to turn them off when not in use unless you want your electric bill to go through the roof!
*edit*
While I don't own the XPA-1 Gen 2 amps, I do have a trio of their baby brother, the XPA-1L. I couldn't be happier with them. Simply because of lack of space and not enough ventilation (yet) I tend to only put mine in pure Class A when listening to music. They can get mighty warm and my listening isn't quite so critical when watching TV/movies so I put them in A/B mode.

The mode you want is class A. And the key thing to remember is that this doesn't limit your headroom or max watts the amp can deliver vs the class AB mode. And if it's anything like my amp - leave it turned on  |

Thanks guys,
Yes Krazy. They lived up to my expectations. Well made professional looking and a fair price.
James up a bit with work this week and won't have that much time to launch some tunes. Looking forward to next week when I will have more time to play.
