"Ever used a Spectral solid-state amp?"
When I was in Beserkeley a few months ago, my friend and I went to Music Lovers Audio (again), where we heard a Spectral CD player with a Spectral preamp and Spectral monoblocks driving a pair of Wilson Alexia speakers (which, btw, I liked more than the Alexandria's). We put on a couple of recordings which I made many years ago, and, seriously, they sounded great (and I was quite pleased with myself). My friend commented that he has a lot of respect for Keith Johnson, saying (paraphrasing here) that he's one of the few guys who really does work at trying to "get it right".

I sure love my Berkeley Dacs!
Seems to me that I saw one of their products at Music Lovers - I vaguely remember a component that had their logo on the top of the case, I think. I'll check them out next time I'm in town.
Anyway, my experience with horns is that, at least in the past (say, the 1940's to 1970's designs), manufacturers tried to squeeze too much performance out of a horn. Throat size (air distortion), mouth-to-world interface (impedance matching), metal horn ringing, internal reflections, were some of the problems. The first horns which I heard that actually sounded pretty decent were the Electro-Voice CD horns - the white horns, in about '73 or '74. They blew the Altecs and JBLs away. When I was doing the sound for a little rock band in '75/'76, we had some JBL radial exponential horns which were awful, and one of my first goals was to replace them with the new E-V horns. The band was ecstatic.
Somewhere around that time period, John Meyer decided to go one step farther, and built electronics to "pre-distort" the input signal, so that the horn distortion itself would actually compliment the pre-distorted signal and result in a cleaner output. I don't remember offhand if John Curl was involved in that research or design, and I don't know what the current status of the concept is.
Anyway, horn design has come a long way since the legacy days of "traditional" exponential horns, thank goodness!
