Default Adding Volume controls to DAC output?

I need information on adding a volume control for each channel of a DAC. It is a solid state unit with RCA outs. Thanks.

What I would like to do is add one to each channel and I am wondering what value pot would be best. This would be a hard wire install.

You need to provide more information than "It is a solid state unit with RCA outs"...

It is a Peter Daniel NOS DAC. I would guess the output impedence is around 50 ohms and close to the two volt out standard.

Then a 100-200 ohm would be all right... Lower is better for longer connections.
I wasn't kidding with the headphones volume - is low impedance, therefore lower thermal noise, lower capacity influence, lower interferences from outside EMF...

Do consider: DAC chip -> volume control -> buffer -> connection to outside
