The Sony has a lot better build quality than the 963sa, so if build quality is paramount to a good transpot, then i would say go with the 9000.
The 963 offers superior sacd playback, but it is not as big of a difference as the redbook playback, when compared to the 9000es.
Also, nobody has mentioned using the 963 as a transport in the many posts i have read before purchasing.
I am waiting for the nex't gen Sony with firewire out to hit our shores, and hoping a dsd dac to go with it, comes out in the nex't year or so.
And not the 10k dac available now.
If i get bored with the 963 sonics before then, i will do open heart with Blackgates and a superclock 2 ect before going the dac route.
