Wow! I didn't know it's been around since 2003!
I'm looking at the January 2008 price sheet and I see all the models.
There is a KP-100S which retails at $749 and sells for $674 MAP, a KP-80 which is about $50 less than the 80 but seems to be mono, not stereo and a KP-500SN which is 250 Watts per channel and MAPs at $1300.00.
My review is in total agreement with the older reviews linked to here.
Ian, I'm playing the PSRS900 and the PSRS700oriental through the Motion Sound and they sound great!
Thanks for the quick responses
