I've lost track of the Sony SACD DVD model numbers. Assuming this is the original, or at least sonically equivalent, the following applies (In my case):
Shortly after they first came out I brought home the Sony to compare against my Arcam Alpha 7SE and preferred the Arcam. I've since replaced the 7SE with an Alpha 9. The 9 is substantially better than the 7SE in every way that I can think of. So, doing the algebra, I don't think the Sony would stand much of a chance against the ring DACs on redbook.
