Or maybe build more flexibility into my pre-amp so it can be used as either passive (DCB1 attenuation only) or active (DCB1 fed into BA-3 for gain).

So many projects...
So add another project! If you haven't already, check out the AKSA Lender Preamp by Hugh Dean and XRK971. It can create the voltage swing needed to really power the MoFo. And you can configure it with different daughter boards for different gain levels or even a headphone amp configuration. I have mine running at a more or less standard gain setting right now but I plan to build another set of high gain daughter boards when I get my MoFo up and running.
