Initial impressions, Axiom exceed in all aspects except vocals.

I had to google the effect I am hearing in KEF. so google says it calls Vibrato, while listening to All My Tears, I can hear Ane Brun holding those notes in vibrato so beautifully that it brings out emotions and gives chills. Further I can hear nuances in her breathing between words that no other speaker I tested pronounces them so beautifully. I am beginning to think its either the Denon PMA-600NE not able to deliver or KEF doing something wonky with their DSP. I hold Axiom to a very high regard, if they aren't able to produce these same effects, is something wrong with the AMP or the speakers not delivering!
