I added some more photos as requested by A’gon member.
Today, I did some more exploring in Canada for the Yamaha NS5000. Canadian dealer will find out if there are any legal reasons why this speaker cannot be imported into the USA. Dealer has no issue getting me the speaker to my home. He will take care of all the paperwork.
GIK Treatments were delayed shipping last week and were only shipped today. So sometime next week will be when I should have them.
List of speakers that I think will now work with acoustic treatments and DSP.
1) Vandersteen Treo CT (heard it but need 1 on 1 demo this time)
2) Vivid Kaya 90 (heard it but only Kaya 45 or Kaya 25 will work in my room. Not really interested in the 25, need 1 on 1 demo this time)
3) Magico A3 (Heard it and liked it)
4) Harbeth SHL5+ (Have not heard it but will call local dealer in 2 weeks)
5) Paradigm Persona 5F (Will hear it again tomorrow with DSP though the Persona 3F is what I would want for the room)
5) Yamaha NS5000 (Have not heard it, but very interested in it, classified as a bookshelf but it really is not).

6) KEF Reference 1, TAD ME1 (Will work in my room but lack of enthusiasm for them)
My understanding of the sound characteristics of my list from musical-to-detailed sound (left to right): Harbeth, Vandersteen, Yamaha, TAD, Magico, KEF, Paradigm. Some rounding error likely present.
