I'm late to the game here, but I thought I could chip in. I just got to do a same-day comparison of the new Contour 30 and a used pair of Confidence C2 mk ii (2013) at my local shop. Though we didn't quite do a side-by-side (different amplification, room, but same source) comparison, the C2s were the winner in my book. I do agree with the general complaint that bass is lacking in the C2s. This was definitely true, but the Contours didn't perform much better in that regard. However, C2's imaging and Detail was absolutely outstanding. Seriously, the detail was almost too real; the buzzing of Stevie Ray Vaughan's amplifier was easily audible, not so on the Contours.
Caveat: The C2s cost $2k more than the Contours.
On the other hand: Worth every penny.
