Actually I was thinking to suggest you one of the Pathos integrated... but then i realize they don't have tone controls. I listen mostly soft rock/ jazz with your same system (Pathos + Auditor), but i know what you mean when you say that your music needs some " help", I tryed the Krell 400x with the Auditor and definitely it gives that "punch" I guess your looking for... the Krell is faster and with tighter bass then the Logos, but maybe a little more fatiguing to my ears after a while.
Give it a shot, you're not gonna waste your time.
Let me know your impressions.
