Wow: Ezmaraldo, fascinating post (as always) and now onto the thread. Pete: Your space seems a bit small to optimize traditional horn systems unless you can place them near the short wall and be seated approx. 3', or so, from the opposing wall (most horn systems require a greater listening distance, than traditional dynamic speakers, in order to bring "things" such as coherency together). This is one of the reasons that "horns" have a modern love/hate persona as many people do not incorporate them properly into their systems/rooms (near field horns - gimme a break). This said, if you can accommodate 12' (or more) of distance between the listening position and the speakers, go for it, it will sound "OK" throughout the room, but the sweet spot will be sweet indeed. Instead of experimenting with this or that (as far as tube amps go) take the leap and work with "single ended" and/or "single ended triode" amps only which is what horn type speakers were originally used with in the beginning (instead of push/pull configurations). Screw distortion spec's, etc., (other than component matching specs) as they mean very little in this realm and the sound/realism is what "walks the walk". If your listening distance needs to be less "than the above" then maybe figure out efficient dynamic speakers in a "near field" configuration, again with a SE or SET amp. The amps (decent ones) start @ around $500, or so and go up (way up). I have used push/pull tube amps for over 30 years, but recently (a year or so ago) went with SET and there is no comparison when these amps are used properly within a system/room. You are definitely on the right track, so hang in there. Please, feel free to email me directly on this subject if you like. By the way, I am not an artist, but a collector (currently short on funds:-).
