I have the Vandy 2ce Sig II’s with a Belles Aria int. amp and AQ GO4 double run bi-wire speaker cables. Your system is probably 3x more expensive than mine, but I share the same exact opinion as you. That there is something lacking with respect to detail while listening at low and moderate levels. Perhaps this is something inherent in the ’Vandersteen’ sound?
Lately I’ve found myself listening to my system while sitting on the floor about 3 feet away from the speakers. When I do this I feel like I step into a 3D holographic world of sound. There is a lack of low end when I do this but the sound is rich in detail.
Could this be indicative of problems with my room or speaker setup?
