The xp/jv string sounds tend to sound very mushy, and actualy come off more as "string-pads" than anything else.

The strings on a TRITON and kurz 2500 simply blow away the xp/jv strings. You can actually hear the strings cutting on some of the patches. For cinematic strings, I would definately go the Kurz 2500,2000 or TRITON route.

The TR-rack also has some great string sounds for a bit cheaper.
