Wow. Lot'sa questions.
I'm not sure I know the answer. So, here's what I know...
The AA Capitole II with the DCC2 is tons better just using the pre-amp section over then Capitole's pre-amp. I had a Philips SACD 1000 modded by EMM prior to the CDSD and it was not as precise, full and detailed as with the CDSD. I did not run it without the optical connections, so I can't tell you how it would be without the external clock upgrade.
I have also owned a Sony SACD1000. The music is much less detailed than with any setup I have had using the DCC2.
Hopefully, some of the others who have owned this gear and have played A/B will chime in and clear up your question.
