Sony UPB-X1000ES as a two channel stereo SACD player

Thanks for your response.
I am not a fan of Sony ES player. Actually, I am not biased toward any brand. 
I've had a few cheap ~ mid priced players (like NAD C 540, Marantz CD recorder DR700, Arcam FMJ CD23, Sony DVP-NS999ES).
My problem is, I cannot tell much difference from all those players I've had. 
For phono preamp and phono cartridges, I could readily tell the differences between different brands at difference price levels, but not on CD players. (I'm using Ortfon SPUs and low MC cartridges now).
I'll give a try to Sony 5400ES. I"ve been also thinking at Oppo 150. If the price is the same (indeed they look like sell at around $1000~$1200, used), Sony 5400ES will be a better CD/SACD player? Or, the difference would be minimal and it is up to listener's taste?
Thanks again.

I’m not sure whether the Yamaha player would be noticeably better than Sony DVP-NS999ES on CD or SACD.
If Sony 5400ES (the flagship player a while ago) or Oppo 150 (something that everybody regards high) would not sound noticeably better than any of players that I mentioned, how high would I need to look at?
Thanks again.

I bought Oppo 105D and Esoteric UZ-1, both used.
Oppo does not sound noticeably better than my other players on my system.
My system is Plinius power/pre amp and Harbeth compact 7 speakers.
Esoteric indeed sound noticeably better. I guess now I can listen to my CDs.
I’ll use Oppo as a Blu-Ray player.
 I’ll play around with some different ICs and speaker cables. Will post later about my findings.
Again, thanks for your response.
