Thank you to everyone who has posted here, this is a wonderful thought provoking, insightful thread, so many great comments.
I built Onken speakers from info a friend directed me to and info I found on the net. Jean Hiraga who is mentioned above was the author for the articles I found. It surprised me that given the size of homes in Japan that the Onkens are so big. I used Altec 416-8A drivers and Altec 811 horns with Altec 806A drivers which are crossed at 800 hz using crossovers I built.
I use Audio Note Kit 300B mono block amps and their Mentor preamp.
A lot of what has been mentioned here applies to my system, great resolution at low levels, non fatiguing, wonderful sound that draws me back for more.
I also have several SS systems that I also enjoy.
Again I find this a wonderful thread that many of the posters I have not seen post before.
