Hello essentialaudio: your point is well taken. The room is elongated, 15 x25'. Amplification will be tailored to the speaker. For Vandy, it would be used aesthetix (io + atlas). For Quad, IO preamp, and EAR 861 integrated amp (preamp section can be bypassed), or maybe Rogue Atlas based on this test published on the 6 moons site:
http://www.6moons.com/audioreviews/roadtour7/roadtour3again.html Given the narrow room, and low dispersion/wall artifact of the Quads, that's a plus for them (they would be placed facing the long axis of the room). I intend to hire a room treatment specialist after the system is completed, which for Quads to have whatever bass they are capable of, is essential. Even with the Vandersteen reputation for value, the price delta is still remarkable...$10,700 for Quatro woods, and pair of Quads Unlimited: $4100.
