I had much larger images, but when I addded them to the post the software shrunk them. Attenuators get complicated. The DAC chip can drive fairly low impedance loads, BUT I don't know how well it does that. When designing an attenuator you have a choice of the resistances used: go for low resistance in order to have a low output impedance to drive anything, but then your output circuit is ALWAYS driving a low impedance load, or go with the higher resistance network which doesn't load the output as much, and then risk not having enough drive for for some devices. It's a tough decission. A big part of the decission is how the output sounds under varying loads, until it gets built and I have time to play with it I won't know the answer to that.
