Would an SACD Player improve my sound?


I currently have a pair of Quad electrostatics with Thor
TPA 150 amps, Thor linestage with a Blue Note Stibbert Improved cd player, and a Cary 306/200 which I use as a transport with a Thor Audio Dac. I have about 20 SACD titles.(currently listen to the cd layer)

Question:Would I get more resolution and better sound with a SACD with a maximum of $2000.00, perhaps a SOny SACD ES- 5400, than what I currently listen to. In short, will a
fairly good SACD player give me better sound (on the theory that there is more information on an SACD vs. a CD)
than a high quality CD player than I currently have?
I am willing ot take a shot at a purchase if an improved listening experience occurs.
Any thoughts would be appreciated.

Nice set up, I have the THOR Cantantus phono preamp.
That said, I was at my friendly neighborhood hi-fi shop, since moved and then closed, sigh, and they had a Diana Krall CD playing on a so-so mid fi entry level set up. The CD player was SACD capable. Knowing me, they popped the SACD version of the same album on in SACD and asked me what I thought. That did it, bought a Marantz SACD machine and haven't looked back. Would do the same today but likely something different.
Do yourself a favor, take a few of the SACD's you have, go to your local store and see what they sound like in a far less resolving system for both CD and SACD and then decide.
If you can borrow one for a few days, even better. Your ears alone will tell you if its worth it.
SACDs are better IMO... but I don't know if I'd spend $2k on a player for 20 discs.

I'd try to borrow one from a local audio buddy and see if its worth it... it might be.
since you have an excellent cdp, and your sacd use is incidental, i might try buying a very inexpensive universal player (e.g. a used denon, integra or pioneer elite) for your sacd. esp. when connected to the thor, any of these should do you nicely for $100 or so, with the added bonus of having dvd capability.
