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?!

Really interesting post.  I too have a pair of Wharfedale Denton 80th Anniversary speakers running Bluesound (Tidal) in my basement "man-cave".  I'm continually shocked by how good they sound as I run through some "retro" equipment - a Marantz 170DC amp and Luxman CL-350 preamp.  I've always attributed the sweet sound mainly to the room acoustics but maybe I should be giving the speakers a bit more credit!
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.
