DXS Connections

I have a DXS on order and would like any opinions on how I think I am going to connect everything.

I have a MD with COAX in and out as well as optical, a DVD with Coax out as well as optical and 2 CD changers with optical. My receiver has one Coax in, plus 2 useable optical in and one out.

I was thinking of connecting my MD and DVD coax out to the DXS, my 2 CD players optical out to the DXS. Connecting the DXS Coax out to my Receivers Coax in.

Conecting the MD optical out on the receiver to an optical in on the DXS and Coax out on the DXS to Coax in on the MD.

I am not sure that I ave got the MD connections right for recording from the CD Changers.

I am using Coax as I beleive that to be the highest quality interconnect.
