Upgrade to Polk CS2?

baboon

What is the main difference between the CS1 and CS2 other than the size. The specs are almost the same. I have a Marantz SR8400 AV with three Marantz MA-700 monoblocks and Monitor 60, PSW505 and some Athena WS-100 for my rears. Will there be a difference if upgraded to CS2?

Thanks
