@ctsooner All of the speakers I have focused on I have heard, except for the Harbeth and the Yamaha. Of the ones I have heard I think the Persona is my favorite. I could easily live with any of the others in my office. I am not too worried about the speakers. I am also not worried about the separate external amplification or network player. All of these are of high quality that I am looking at. Almost any permutation of the speakers, amps, Network players I have identified would make for a good system (in a big room).
I am only concerned about 1 thing now and that is making a big speaker fit into the small room in a manner so that I can enjoy a good deal of the systems capability. To that end I have done a few things such as cleaning up the room of furniture and getting acoustic treatments. The last thing I am doing, which is to explore DSP, is something that the DSP guys are saying will make my goal a reality.
If I stay in my room lane and get an appropriate sized speaker (small stand mount) I may not need DSP. However, I am trying to do fit an inappropriate sized speaker into this room. The DSP demo I have scheduled will tell me if I have solved the problem.
With regards to the Treo CT I have only heard them with Bryston Cubed stack. The Lyngdorf issue I described was the amplification stage driving the Persona 5F, it was not good. However, the Lyngdorf preamp section impressed the heck out of me and is my leading contender for those duties. The dealer did mention to me that the combo we discovered, Lyngdorf preamp+Simaudio amp was the best he has heard the Persona 5F.
That Persona demo so impressed me that I am now questioning the purchase of the Blade for the downstairs. A large Persona speaker, such as the 9H, is heavier and hard from my kid to move. The Blades are rather easier to dislodge. The front facing woofers on the Persona maybe easier to place compared to the side firing Blade drivers. I still like the Blade more but from a practicality standpoint the Persona is compelling for my downstairs. This is a digression from this thread.
