I heard the large models about 8 months ago in an actual owners home large dedicated room with catherderal ceilings of inexcess of 12 feet. I don't quite understand Oahuans comment because just to set them up with sufficent wall spacing requires a large room. I own Dunlavy SC-V's which aren't exactly small and have them in an 8000 cu foot room. I think I would have a hard time geeting the big Pipe Dreams model to work in my space. Acoustic treatment is a must as is absolutely the best electronics. I do agree with Oahuan that captivating is the right word. The only negative to me personally is that my favorite music is orchestral classical music and for most of my favorite performances the limitation is the recording and not my system. But on superbly recorded music I think they are uniquely in a class by themselves.
