Whenever I think back over components I’ve owned or demo’d in my system, my mind generally centers on one or two aspects that stood out. When I think of the Vandersteen 1C, my immediate impression is one of relaxation. The 1C is laid back, smooth, forgiving, grainless and tonally warm and full. Nothing immediately or obviously wrong stands out. It doesn’t draw attention and thus “steps aside.” While it provides good resolution, it is far from an analytical speaker. Nor is it assertive due to overly prominent mids or highs, or overly “fast” (over-damped) in its bass response. Instead, it invites you into the music and has a very organic, natural (if perhaps slightly “slow”) pacing. The bass is slightly on the full and ill-defined side, but that’s an acceptable compromise in my opinion. I suspect, however, this is mainly due to being driven by 30 push pull tube watts and because my room is on the smaller side for their bass extension. Based on feedback from audio forums, I suspect it would tighten up considerably driven by a solid state amplifier, since my amplifier uses very little global feedback.
