Chuck911 said "The changes heard in my system (and this is by me, Chris did not have the time to A/B this) were towards a more lively, dynamic presentation."
Just a thought, but perhaps what Chris perceived as "added hardness" in another system translates directly to what you heard.
After all, you are using a relatively low powered tubed integrated amp (or were at the time of the aforementioned assessment) in a large room with the speakers way out in the room. Dynamics have never been your systems forte (at least not to these ears) so perhaps Chris's "added hardness" translates to your "lively, dynamic". i.e. a happy synergy.
