CS4397 dac

[fordgtlover]

Hi!

I just want to thank for all the great help I found here.

Just for fun I did a measurement of my Lawrence DAC before I started modding.

This is the frequency measurement before doing anything.



As you can see, the -3db point is at 13.000hz!

After changing out the resistors to the same value and then changing C32, C33, C34, C35 to 150pF it now looked like this!



And it sound great! My wife said that it sounded better than my extensivly modified Zero DAC. And I have to agree. Next step, better opamp and modify the power supply.

Thanks guys for the help!

Thanks for the heads up on the FR. Did you change the resisters as discussed by Leo in this post?

Where he suggests R8,R9,R14,R17 to 30k and C32,C33,C34,C35 to 150pf.
