What is this speaker doing right?


I have a pair of Wharfedale Denton 80th Anniversary speakers running Bluesound (Tidal) through a Creek EVO 100A integrated.  For the past 3 hours I've hands down enjoyed these more than my KEF LS50s.  And I enjoyed listening to this, in subjective terms, more than my rig in a dedicated room. 

The question is, Why?  

The KEFs discretely separate things.  My other system is euphonic.  The Wharfedales have phony mid bass warmth--I love them. 

What is going on?!

I have a pair of these for a bedroom system powered by an NAD C326BEE and C516BEE CD player. They offer a relaxed yet detailed soundstage that is very musical. Wished I had this good a system back in college. Great speakers regardless of price.
I haven't heard your Wharfedales, so I don't have a comment.
However, despite their oft-repeated phase alignment claims, I hear significant phase shift distortion from the KEF's.
Results in discomfort, listener fatigue, and desire to turn them down. Kind of like a Bose 901.
The LS50 FR spec of 79-28kHz +/-3dB is somewhat misleading because it's done under anechoic conditions with no port output. With port output included, Stereophile  measurements show a flat bass response down to 50Hz. The Sound & Vision review also indicates a measured FR of 46-20kHz +/-3.2dB.
