First - a real tangent: Is the original poster actually a Porsche cup car owner? I raced Porsches in IMSA as a professional driver in the 1990's, then in club racing. My wife and have owned 15 911's, including several cup cars. Sorry for the distraction.
About the Wilson speakers - I have a pair of WattPuppy 7 speakers. My local dealer, Paragon Sound here in Ann Arbor (a great place!), as well as Dave Wilson, recommended a room no smaller than 13 x 19 ft. We were careful about adding both diffusers and absorbers to the basement room - great improvement in sound. FWIW- My system is McIntosh, MCT450/D150 into the recently updated C22 tube preamp and then a C275 into the Wilson speakers. The sound is incredible on most of the DSD files that I have, others are too "bright."
