Trumper,

i didn't understand:
- 588 connected analog - this one i get
- 598 connected digitally? this way it worked ad transport only, doesn't it? what did a DAC job?

MCN,
i own 588 and it's very very good.
i really afraid to let it go and loose its RBCD performance. G08 perhaps? ;-)

anyway, for SACD you can later add dedicated player as i did (i checked scd-777es but on RBCD 588 blew it away).
