Sabai,
The X upgrade for the CDSA-SE will only take you to about 70% sound quality of the XDS-1 so if you want better then I recommend you to buy a XDS-1 or something else.
I moved on from mine and couldn't be happier.
BTW, Don't modd the player... keep it stock... I've learnt the hard way which cost me $$$$ to return it back to stock thanks to a so called upgrading company.
