Modding Sony CDP to Non-OS?

203.173.172.238

Hi - newb question... I have an old Sony CDP-590 which I am having a play with. I have tubed the output (Lampizated it), but it till sounds a little fatiguing (I'm mostly vinyl/SET these days).

DSP is CXD2500q -> filter CXD2551P -> dual PCM56P DAC. 8 times OS. Clock is 16.9MHz. I have found most of the chip manuals, but am pretty newbish to DIY digital.

Is it possible to convert to non-OS? I understand the PCM56P might repay a bit of effort. The filter is 4/8 times OS controlled by pin2 - is it as simple as setting that pin low to drop it from 8 times to 4 times OS? Any experience/predictions how much reward from reclocking?

It must be getting on for 20 years old, so replacing all the electrolytics might also be on the agenda.

I'd be grateful for any advice or links - thanks!

Brian
