The Mainline won't take much more than 1.1V, but it has loads more gain than a Crack does (especially with the impedance switch set to High).

Do I need to find a way to reduce the output of my DAC, or use a different DAC?

I would set the output of the DAC all the way up and just use the attenuator on the Mainline as your primary volume control.

So, I know this sounds like a pretty stupid question but, do I want to set up the fan to blow air through the Heatsink or draw air through it? I'm thinking drawing through might be more quiet.

I would blow the air onto the heatsink.

PB, do you know the V output of an rDAC? It seems to be a better match with the Crack. I installed an Noctua Redux 900 fan in one of the MoFos. The fan cooled side is running 12-15 degrees C cooler than the other so I’m going to put the same fan in the other amp and the install the 193 Vs.
