My semi useless two cents. You should really audition OTLs before going on reputation. They have a sonic signature which is hard to describe but most definitely present. I have horns but not Avant Garde everyone said use low power SETs the horns are so efficient. I didn't like the SET sound for the music I intended to play on that system. That being said I have heard OTLs which I thought were outstanding. I would be careful with the OTL and horn you may encounter a overkill and thus fatuiging upper register and a lack of good bass.
