Elso has extensively modded the 931.. I bought one with that purpose but still didn't make any mod....
If you search there are many posts about them, but IIRC the suggested mods were clock replacement and using a external DAC (maybe tapping the IIS signals), and of course power supply tweaking.

I got a copy of the service manual from him.

Regards

Andrea

Hi Hacknet,
The difference is almost none. The servicemanual of the CD931 is just an addendum to that of the CD930. I have given up to find the differences.

Ok,

Fun besides

CD9x0: made in Belgium (hasselt)
CD9x1: made in Singapore

Any other differences:
Maybe different components used since one sound better than the other.

Check the labels (i'm not shure, read it somewhere on the net during surfing). Then open them up and see if the buildquality is the same

my 2 cents

edit: i swear that the JP post was not there when i last looked.
How about that.... btw JP, check your clock.... Not afraid to be asleep tom during the match
