Kawai Synthesizers

I'm new, and have a K1r II in the mail. Currious as to the differences 
between the K1r and K1r II? I have been looking for something different 
and inexpensive to add to my synth setup. After reading and hearing 
(mp3s) of the K1, I feel it's worth a try. My other units are: Arp Axxe 
+ Little Brother, Yamaha AN1x, Oberheim Matrix 1000, Yamaha DX7iiFD, 
Yamaha TG500, Korg 03R/W, Korg Wavestation SR, EMu Esi2000. So as you 
see I got the analog thing covered (the AN1x and Obie layer very 
nicely), the ROMplers (TG500 and 03R/W) are workhorses and are 
different sounding, the DX7 is additive FM heaven but may layer nicely 
with the K1. And the EMu takes care of vintage key sounds along with 
drums and Hammonds and anything else. Currious as to what setups others 
are using the K1s with?
