RCD 930 AX- what dac

Hello guys,
I recently purchased the Rotel 930 ax player for a rly good price. As it hasn't still arrived to me i am getting anxious to see what's inside. After quite an extensive research i was unable to get any reliable information as to what goodies are hidden in the player. I know that it uses Sony transport, but the rest seems to be covered in mistery. :<
I mostly wanna know what DAC is inside; all i know for now is that it is 1bit, but i'd rly love to know the exact chip model. So if someone has that kind of information, please don't hesitate to share. :>

p.s. can't wait to start mod-ing it
