XV costs under 1000$ now.
But SC has most important thing superior - 64 midi channels (wow!), 1600+ patches, 6 FXs (if I'm not wrong)!!!, big display... And the price is lower!!! Why??? Are sounds and FXs inferior to those from xv? Do they sound the same, or it's worth buying them both? XV5080 is out of competion, because extra 1000$ is way too much for what it additionaly offers. The only positive thing are 3 MFXs. Although it could be more, at least 5, like on Tritons and CS6Rs. I think expansion possibilities is not a big deal. I prefer to spend 1000$ for another sound module instead of buying 4 cards. No need in extra outs, in rackmounting possibility (I have table!), in stereoforms (if the sound is good, then it's good), sample playback (I have separate sampler)... You see, XV look way too limited compared to SC. By the way, how much sound memory is there in SC?
