Riced1 - I can't speak for the C series because I have never heard them. I have the D2's. I have heard the Scansonics several times. They each have their own 'house sound'. The tweeter in the Scansoncs is very close to Raidho D and X series. The soundstage and imaging is also very similar. But in my opinion there is a lot more clarity and separation between the instruments and vocals with Raidho because of the blacker background. I will say the same when comparing the X and D series but the X is a lot closer than the Scansonics. I personally believe the Scansonics punch way beyond their price point. Remember the Scansonic 2.5 retails for $3600 USD where the D2 retails between $44,000 and $48,000 depending on the finish. X3 retails for $29,500.
