AXPONA 2017 Protocol

One thing about Axpona is that it is often difficult to find the specific model you are looking to demo.  Dealers do not like to lug so much hardware and the rooms are small to begin with.  Even dealers that have multiple rooms still select only a few models of speakers to display.   Unfortunately I doubt that you will find a single speaker on your list.  
Jeff Joseph usually has his own demo material but might allow you to try something off hours.  Last year his demo speakers were the Profile model.    
A dealer in Woodridge, IL (Holm Audio, 1/2 hr from AXPONA) is a Joseph Audio dealer but I do not think they have the Perspectives.   They do however carry a wide line of PSB speakers.   
Saturday Audio in Chicago is a Monitor Audio dealer and they are willing to set up any speaker in their stock for you to demo.  
All this is not to say you should avoid going, it is a great experience and you get to hear a wide range of products, get familiar with the different "sounds" and products, some of which may surprise you.  
I have gone a few years now and was disappointed at  the limited models available for demo.  But I did hear Harbeth speakers at the Vinnie Rossi room and knew I had to have them.  I went for a demo at Decibel Audio in downtown Chicago and bought a pair.   Based on the speakers on 
Good luck! 

@avanti1960  You are confirming a specific concern regarding the presence or probable absence of the speakers I wish to hear. Having said that, I haven't heard the "house sound" of most of these speakers, so if it provides me a auditory window into that aspect of each the manufacturers I will be farther ahead than I am presently. Thank you for providing your insight and experience.

As I pack my stuff to travel to AXPONA tomorrow I wanted to stop and thank all of you for your insight, advice and commentary on what I can expect. I plan on providing a short overview of what I experience when I return.
Thanks again,
Al

Al I will be there tommorrow too .it will be fun.Bon

@astewart8944 ,
Did you get a chance to listen to the ProAC D30S? I was impressed, with the speakers being driven by Naim. They sounded very dynamic. They are more up-front, than my current system. And the bottom end on these were very deep. One song on which they impressed me was the Boz Scaggs - Thanks to You. They rumbled the room. I had not imagined that these could do it. Last year I was reading a post on this forum where the poster mentioned that he could not get bass from his D30R. Something must have been seriously wrong in his system.
Will wait for you feedback on these, as well as on th Spendor D7, after you audition them.
