I have a pair of Persona B’s. I have a pair of KEF LS50’s. I love the sound of the KEF’s, but after awhile they can sound harsh in my environment—high ceilings and hardwood floors. I ended up getting the Persona B’s after hearing them. These have all the detail and clarity of the KEF’s, but match better with my room. I can listen to these for hours. I’ve done AB comparisons with the KEF’s and prefer the Personas in this room. I just can't part with the KEF's, so the KEF’s will go to carpeted environment.
Roger Kanno’s (SoundstageHIFI) review seems closer to my experience. So glad I heard the Personas before reading Jerry Seigel’s review.
