johnk,
I respect your experience, but the way you state what you just said really makes it sound like it’s necessary to assemble rare parts and pieces from all over the place at considerable trouble and expense to have a good sounding horn system, and I have to disagree with that. If we all had the time, money and expertise to do that I’m sure that the results would be great, but the average audiophile like myself can get good results without going to the extreme.
