Paradigm 3f, KEF reference 3, Monitor Audio PL300II


I've been auditioning speakers in the $15,000 range and am almost ready to decide.  My short list right now is the KEF Reference 3 and the Monitor Audio PL300II.  I'm planning to hear the Paradigm Persona 3f this weekend.  I've also heard speakers from B and W, Wilson, Wilson Benesch and Proac but none made the final cut.  I really expected to be blown away by the Proacs and, while they were very good, I prefer the KEF and Monitor Audio. Unless the Paradigm is even better, it will be a tough call. They both seem to have great imaging and soundstage, reasonable bass and pretty life like presentations.  We all know how hard it is to compare and contrast speakers, especially when there's a large time gap between listening sessions. The Monitor Audio dealer has offered to bring them to my house, set them up and let me live with them for a week at no cost. Sounds like a great offer but I don't want to accept if I'm leaning more towards the KEFs.  Any helpful advice would be appreciated.

I have been auditioning speakers in my listening room, as well as visiting friends on the west coast and listening to their speakers and systems (some have blown close to $1M!). Here is my $0.02, which is probably worth a great deal less.

I AM BIASED: I like highly analytical speakers, not musical speakers such as B&W or Sonus Farber.  I slightly prefer passive speakers, do not like electrostatic speakers and enjoy power amplifiers driven by tube preamps, and do not use vinyl but high-resolution DSD and other file types from TIDAL. I have a 302 sq ft room in my basement (underground) that I insulated along with a professor in audio engineering who is a friend of mine. He used microphones and other devices to achieve a blend of sound absorption and reflection (not an anechoic chamber). 

In the under $20K range, including demo's and slightly used (I try and not spend retail price), here is my list so far. This is biased and I listened to these on a plethora of different systems (not in stores).

  • Paradigm Persona 3Fs or 5Fs: Hard to find these as used or demo models as they are brand new products. For my space, the 3Fs are better but lack a bit of bass. The 3Fs I could find at $10K for a pair (which is how I believe all loudspeakers should be advertised as pairs of speakers, not individual ones), the 5Fs at $16-17K;
  • Wilson Audio Yvettes. Some demos are becoming available at $16-$18K.  Much different than the Paradigms, but slightly better mid-range IMHO for reproduction of strings and orchestral music;
  • Vandersteen Wood Quatro CTs. Wonderful speakers, $14,600;
  • KEF Blade 2's. Hard to get discounted, but have found some advertised for under $20K;
  • ATC SCM40As.
These are what I like so far...also have wonderful Focal Utopia headphones. Thanks for listening - Gerry
Your perception of analytical vs musical is so hilariously skewed.  

Literally every speaker you mentioned in either category is very musical.  Then you go on to say you like tubes...  which are usually more “musical” and not analytical at all.

My head is spinning.   Good luck.
I've never read someone say they like analytical speakers then go on to call B&W "musical". My impressions are the exact opposite. 
I have the Monitor pl300ii’s and they’re amazing!! I don’t think you can do much better!! Obviously, it all comes down to personal preference in sound, but I can promise you the Pl300ii wouldn’t disappoint you!! Plus, please don’t pay full retail!!
