Brian,
I do not have Heresy III's but do own Heresy I's and Heresy II's. Both sound wonderful in their locations and with their respective gear. My HI's are in a spare bedroom(13'Lx13'Wx10'H) being driven with a NAD AVR T773 and CD player C542. Horns not overwhelming or brittle and bass is sufficient for most music but adding a fast/punchy subwoofer can help. I find this rig to be very revealing and punchy with pretty "accurate" tones. I have found that the HI's as well as HII's are not too selective with amplification and excel well with 50w/ch tubes as well as 250W/ch SS.
Of course this is my experience but do yourself a favor and head over to the Klipsch Forum and more specifically the "2-Channel Home Audio" and "Talkin' Tubes" sections and propose your questions.
