I just made that comparision at my dealer but without the sub. The reason for no sub was because both me and the dealer have Rel subs. The dealer and I find the bass from either the C1 or C2 is faster and tighter than the Rel. I did the comparision in hopes that if I upgrade my C1's to the C2's I would use a little less of the Rel. Last we used Nordost and Jps in the comparision.
The comparision
First the C2's are a little more efficient but at low but equal volumes neither of us could tell any difference. At moderate levels you could hear a little deeper bass but not $6k worth. At high volumes the C2's went deeper in the bass and louder. I mentioned speaker cables only because I found with the Jps superconductor3 and the deepest of bass notes they sounded a hair 'boomy'. Those cables seem to be a better match with a rel sub (need high level inputs which dyn still does not offer on its subs). The nordost had better timber and decay. So in my personal opinion at low to moderate listening levels the are almost the same. Since I dont listen at high levels very often for now I decided to keep the C1's.
Yes the Sapphire is still limited to 1000 copies and the only new speaker I know of and saw is the focus 360. To me the sapphire is more forward sounding in the midrange and bass compared to the confidence series.
