Beocreate has a built-in ADAU151 DSP, so it is similar to miniDSP where the software is just a front end for programming that DSP. It has been a while since I looked at the Beocreate software but it is web based and seemed pretty flexible IIRC. My main complaint was that you used sliders to select values like frequency, Q, boost / cut, etc which was a bit of a pain.
I measured the response of various filters implemented on the Beocreate and compared to miniDSP, notably the shelf filters are definitely different between the two. Peaking filters and crossovers (I only tried second order) were the same. Like a miniDSP the Beocreate can accept biquad coefficients but the convention is a bit different with A1 and A2 swapped compared to miniDSP. Using a biquad is a good way to make sure you get the same shelf filter response as miniDSP.
If you do go with Beocreate let me know and I will fire it up again and can send you the necessary DSP settings.
Good point on the TOSLINK output
@somebodyelse, definitely a really nice feature for daisy chaining an additional DSP for subs.
