This morning I took advantage of a rare window of time to poke around on AC and discovered Tortuga for the first time. The LRD-based volume attenuation sounds like a seriously cool implementation!
After lurking in the audio shadows for many years I've decided to build some open baffle speakers, very likely one of Perry Marshall's Live Edge Dipoles or a close derivative thereof.

I'm open to other speaker suggestions, but anyway, Perry's designs use a MiniDSP Flex 8 to manipulate the signal in the digital domain, then internal DACS for the outputs to the amps (although I might get a version that uses digital out so that I can choose different DACs).
My apologies in advance if this is a blindingly obvious no :), but I thought I'd ask the question anyway--is there a way to combine your LRD-based building blocks with digital-only DSP?

The challenge with using Tortuga LDR attenuation together with muti-channel DSP is that Tortuga is really only compatible with 2 channel (left & right) stereo. If you intend to use DSP to ultimately produce active left(Hi, Mid, Lo) and right(Hi, Mid, Lo) analog signals, you need 6 channel attenuation.
I've used Tortuga LDR preamps with DSP but with the 2 channel LDR preamp upstream of the DSP. It worked reasonably well in my opinion but you end up with the complexity of digital source -> DAC -> LDR preamp -> DSP (ADC plus DAC) -> multi-channel analog amps.
