I heard the V2s and C2's, sorry, not the C4's, on the same day. The V2's are good speakers. Good dynamics, imaging, and extension. I thought these would be pretty good with orchestral works. I actually preferred SF Cremona's to the V2's on small scale works and vocals. I did not like the V2's as much as Wilson Sophia 3's, which are about the same price new. The V2's could be a good purchase for the right price, depending on your taste in music.
If the C4's sound anything like the C2's I'd pass. I was not impressed at all with the C2's.
