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.

I would think that the SA-11S3 would represent a worthwhile upgrade. Marantz CDP's tend to be on the warmer, more musical side of the fence. If you are seeking more resolution, you may want to look at an Esoteric K-07X.

One other consideration is possibly upgrading the Sony. I know Dan Wright of Modwright does some great mods with Sony players, like his Ultimate Truth mod. The question is how old is the CDP, and is it worth it to sink a couple grand into a 10 year old model? Maybe not a wise decision, but something to consider if you feel it still operates flawlessly..
Thanks for the replies so far. I wish I could just be happy with the stuff I have and leave it at that. 4 amps four sets of speakers later I'm still on the quest. I love my amp and pre-amp no need to change again. The SACDs on the Sony CDP are amazing and I'd have to sell it at a huge loss but I have to think that newer DACs are even better.
