I've been considering this upgrade myself, as I own some original VR-4s. I'm a musician by trade, and prefer musicality to hyper detail. Will I end up missing anything from the beautiful sound I already have, or will the improvements be more than just greater detail? Is the broad swath of frequency covered by the midrange driver of the VR-44 a huge difference in tonal character? I've never listened to full range drivers before, so I'm not familiar with that sort of sound. Thanks for any input!
