Looking again at the EdgarHorns, the placement in the room seems nearly optimal and they are now properly time aligned.  Looking at the phase of the individual drivers and listening to each of them individually revealed that the tweeter was wired out of phase and the midrange and woofer were wired out of absolute phase,  Correcting this changed the sound from very good to stunning.  The speakers now disappear in the room and the sound is the best I have ever heard from a stereo.  Really wonderful to listen to, now! 

I understand why the previous owner traded these in for Cain & Cain horns; because the EdgarHorns were wired wrong!  I am amazed this could happen by a small manufacturer like Bruce Edgar who seems to take a lot of care about his products. 

But comparing to the sound of live music, it is still slightly blunted and like everything is stuck in the mud, so it gets a bit confused especially with orchestral music and begins to lose the living presence, although with small ensemble work the sound is very much lifelike and I can easily forget I am listening to stereo at times.  Next I think it will be appropriate to look at the level of the lower midrange horn and to consider rewiring the insides with good solid core wire (it is all Litz copper wire now).

Does this sound reasonable as a next step?
