System Goals/Comments:	Some things I have taken to heart: "Audio today consists of a much wider range of practice than you'll find reported in the glossy mags. Some of the most interesting activity in the hobby takes place outside the borders that commercial producers of contemporary equipment accept as their playing field. ... [O]ne should keep an open mind about different ways of being." -Joe Roberts, Sound Practices, Summer '92 "No [triode] is perfect but all are tasty ... and I always wind up back with the 2A3." -Terry Cain, Audio Asylum, 6/12/03 "The very first thing that should be horn loaded in a system is the bass ... midrange is second." -Jeffrey Jackson, Audio Asylum, 10/27/03 "If you're lucky, you can get a capable horn system together in five years. If you're really lucky, ten." -Munna, in conversation, Summer '19 "The good news for us horn guys though is that, as always, knowledge is more valuable than a pocket full of loot and the determined hobbyist can almost always build something better than what can be bought, and for a lot less cash." -Steve Schell, Audio Asylum, 3/1/13
