SV-1 Sounds inclouded in the Kronos X ?

[Funky40]

I recently saw the SV-1 Mentioned in several "should i get a Real Rhodes or what else ?" and "replacing my Piano with ?" kind of Threads .

Now, i have a Kronos X and wonder if i have those SV-1 capabilitys and greatness allready given in my Kronos ?
I ask just to get a idea to what level of sounds, mainly the Rhodes ones, these people refer.

Or has the SV-1 something to deliver that the KronosX is not capable of ?
