Power ouput of these amps is more like only 12 watts, not 1200. However that might be enough depending upon speaker sensitivity? My 104dB horns seem to like about 200 watts/ch if I'm really rockin'-the-house, otherwise 5 watts is generally plenty for some still pretty darn loud SPL's. Plato raises a very good point regarding preamp idle noise though. Even though these horns were designed & built before solid state componentry was even available, I've never been able to get used to that tube-rush idle noise when running tube equipment into horns. There are probably some tube pre's that are quiet enough, but none that I tried were really acceptable; maybe the Golden Tube SEP2 or SEP3 but not a Cary or VTL.
