I remember listening to some Energy speakers in the past (can't recall the model) and as far as I remember, the sound was very different than Axiom. They are more of a laid back speaker (which is a reason why I didn't really like them) as opposed to the more forward (ie neutral) sound of Axiom. Therefore I am not sure that the QS8s would complement your system as well as other Energy speakers, you might end up with a completely tonal/timber mismatch. Again maybe this "laid back" doesn't apply to all Energy speakers.
