I would follow the source upgrade or addition with the Preamp. If you play your cards right..you can come out with extra cash to go towards the speakers or the preamp....your choice.
Honestly before I paid to mod the Sony. I would just add a DAC.It is the safest way to go. You could always return it if it doesn't work out. Use the analog outputs of the player for SACD.Use the digital out for your redbook thru the DAC.
I came across a fellow(dcbingaman)on audiocircle with your cd player. Here's his comments regarding the stock Lite Audio DAC 60 compared to the Sony SCD-C555ES. Never heard this DAC but it does look like a viable move. You may want to check return policies with the companies you deal with. GR Research sales this line of DACs and they also modify some of the units.
