How to mod an 1820 (not 1820M) Audiodock/soundcard??

[Iceman_jkh]

Greetings Everyone... long time reader first time poster.

I have been reading up on the 1820M and 1212M modding threads regarding Opamp upgrades, cap bypasses, power supply improvement and RJ-45 cable improvements.

A few of the threads which I have read:
Fully Modded E-mu 1212m with pics and impressions (so far):
Too much time on their hands?
How did you Mod your EMU?:
Sony mdr-SA1000 opinions much appreciated
Emu 1820m impressions:
FS: Three Sony Discman catalogs

All very good threads, but unfortunately all the pictures which used to be available as guides have been removed or are unavailable. I am receiving my 1820 (not 1820m) unit this week and I wanted to get a jump on it by requesting any information people have regarding performing this mod.

Differences between the 1820 and 1820m:
_________________1820__________1820-m
----------------------------------------------------
ADC:___________BB PCM1804_____AKM AK5394
Output Opamp:__N5532__________JRC2068
DAC:___________CS4392_________CS4398


I have read that the 1820 and 1820m have the exact same circuit board, and that only the ADC, DAC & Opamps differ.
Therefore, can anyone confirm if it is possible to swap the ADC, DAC & Opamps of the 1820 to the same as that of the 1820m (or better amps: LM4562MA) to turn it into a fully fledged 1820m? I am happy to provide any pictures of the board/audiodock if requested.

I am looking for the most efficient mods to perform if possible. So if anyone knows which mods give the biggest gains relative to their difficulty/cost please include that information.

Thank you kindly.

Can anyone rehost or point me in the right direction or even email me the pics of these mods?

Thanks
