I'm very confident that the acoustic sounds of the E-A7 are way, way superior to the old JV and also XV samples that are standard samples from the 1990s and millenium. From all demos I listened to and briefly browsing though some sounds myself at a store a few years ago, the E-A7 is probably a combination of SonicCell sounds derived from the Fantom X and newer and many sounds created for the Roland Europe arranger line (E80, BK series). These are far superior to the old JV and XV sounds, which could nowhere compete in today's arrangers.
