I currently use and nanoDigi (fully-digital, no analog) miniDSP between a Chromecast Audio and a Rotel 2-channel amp with a fully digital signal path from the CCA to the Rotel which handles the DAC. I am getting ready to begin integrating a pair of subs and the plan was originally to drive the subs through the amp’s pre-outs so the mini-Dsp would handle room correction for the subs along with some B&W “flaw repair” on the main speakers.
The drawback to his approach is that I can’t high-pass the main speakers since the dsp is sending both full-frequency channels through the amp which also handles volume control.
It occurred to me this evening that if I add a DAC between the miniDSP and the subs, I would have the ability to process the signals between the subs and mains independently so I would pick up a few extra PEQ channels on the subs and the ability to high-pass the mains. Seems like a fair amount of benefit for a modestly price DAC. The miniDSP will have to have to handle volume control which is doable with my harmony remote.
Anyway, is there something specific I should look for in a low-frequency only DAC? The input would be SPDIF out of the miniDSP and I was eyeing the Topping D30 as the price and feature-set seems appropriate for this use case. Any benefit to moving up the ladder to a D50? I figure distortion and such is already pretty high down in that frequency range and noise shouldn’t be much of an issue so would a $10 SPDIF to RCA L/R “converter” work just as well?

Thanks for getting this far if you made it through all of that, lol.
