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.

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.
You may want to consider upgrading your Thor linestage ( T1000 ? ) with the new Mundorf Caps..I did my T1000 and its a huge improvement over the last current model...My guess is you will get more performence this way than going to a SACD and buying $40 cds...Highendaudio.com ask for Ted ( owner of Thor Audio ) ........
I would suggest checking out the TRL modded Sony 595 for $350 that just popped up on Audiogon. I know nothing about the seller or the specific deck but I can vouch for the 595. I owned this sacd player for a few years and loved it. I only sold it to trade up the TRL line. There is a review on 6 moons among other other places.

SACD's range from slightly better to spectacular depending on the particular SACD/CD.
If you listen to classical and jazz (more classical) it will be well worth getting an SACD player. I favor the Marantz players. I would buy new which gets you into the reference line and an sa-15s2. BTW the redbook playback is very good.
Alot of the xrcd and K2HD cds are outstanding and can be played on regular cd player --would try 1 or 2 first as I find most of these better than sacd but agree some sacd's are outstanding.
