Of course, if you want to really get in to it and you are capable of spending the extra money, then, of course, the Axiom amps are the next level.

I find this statement rather bold.

Can you please explain to me why and how the Axiom ADA 1500 - 5 channel, with 300 watts per channel and a $3100 price tag is the next level compared to the Emotiva XPR5 - 5 channel, with 400 watts per channel and a $2300 price tag?

Add to that the incredibly positive reviews for both products...why is it that the axiom amplifier is "of course, the next level"?

I mean everyone is entitled to their opinion of course, but you stated it more matter of factly, then mere opinion, so I'm just curious why you feel this way?
