After looking at the internals, I don't think it would be a substantial upgrade. Take a look at Denon's DCD-SX1 for an ultimate / affordable SACD player.
Marantz SA-11S3 vs Sony XA9000ES
Hello all, my question is, would I hear a noticeable sound improvement replacing my very nice but older Sony XA9000ES SACD player with the Marantz SA-11S3 Reference SACD player? System consists of a Rogue Zuess tube amp, Rogue Super Magnum 99 tube preamp, Shunyata Hydra line conditioner, Martin Logan Summit speakers and all upper end Audioquest speaker cable and interconnects. I don't have the cash yet for the analog rig that I desire so I thought this may be a good upgrade in the 4K range. Any thoughts would be greatly appreciated. Thank you.
