My understanding is that the CSP comes standard with two RCA source input pairs and one stereo output pair and one mono output. An option for $100 is two stereo outputs and no mono output. I would suggest going to Decware.com and reading about the CSP 2....the CSP 3 write up hasn't been posted yet. Also if you click on the "add to cart" link you can see the available options and their cost. From reading here and a letter from Steve a couple days ago, another unlisted option is two XLR headphone jacks in place of the standard single ended jacks....don't know the cost. Hope this helps....Mark.
Thanks Mark, two outputs is exactly what I need.
This really puts the pressure on me to order one of these before the site is updated...my wife is gonna kill me
