Default Lite DAC-AH resistor Values

Does anyone know what the resistor values for the data in resistors to the DAC chips? I believe they are R3, R8, R11, R14, R15, R18, R21, R24 in this schematic. Do you think swapping them out would make an appreciable difference?

Thanks

as long as you leave the 5532 opamp on the board, it does not matter...

On a serious note: I have tried several values between 10 and 100 Ohm and hear no difference

Its better to use >20ohm resistors. I had just bad experience with 10ohm resistors.
After changing to 80ohm resistors, oscillation disappeared.

Thanks. I'm actually bypassing the output stage with a Jupiter 2.2uF cap and it sounds great. I'm going to change the R35 and R36 resistors as well with Riken Ohm's. Just trying to see if there's any benefit to changing the other ones since they are inline with the signal path. So any value greater than 20ohm is okay?

Yes, 20 to 100ohm if fine.
