There is an Dac that has inbuilt DSP for at least active crossovers, Danville Signal DSPNexus 2/8 or 2/16 but as soon a good DSP is implemented the price will increase pretty much, like Dsp Nexus 2 in 8 out (2 XLR and/or USB in and 8 XLR out), $3000, hefty price, but if one considering an Okto Dac 8 pro and Acourate convolver and crossover, the price does not differ very much if you need to buy a decent pc €1000, Windows Licence, Acourate Convolver €150, Acourate Tool Box €340, Okto Dac 8 Pro with Apple remote 1686 €, then the Danville DspNexus 2/8 complete solution is not far way even if importing it to eu. The this new from Topping withiut any dsp software, which is not really needed when there is both free and paid programs for thand problably it sounds as goood as my Okto Dac 8 Pro, i wouldn't be suprised if it did.
There’s no consumer codec available for spatial audio (Atmos, etc.)
No there is not any software codec that lets you route to specifi channels, but a codec exist in windows for connecting to AVR or compatible heasphones , Dolby Access and DTS:X Ultra apps, to decode the given spatial audio in games and movies. But i think this will come in time when people will buy multichannel dacs for multi purpose enetertainment in livingrooms, not just as it is now, for multi-way speaker systems in an extremem hobbyist world or for movies most often with an avr. And why i belive that is gonna happen is that all consumer AVR:s dsp:s tend to downsample everything to 48khz, and they actually dont sound that good with music, had an Marantz Sr7010, sold it in favour of the Okto,
Stay as far away as you can from that train wreck
Deqx is still the proven all in 1, they have a new series about to launch that is even simpler to use. Very expensive though. Hopefully Amir can get his hands on one sometime
Danville Signal DSP Nexus 2/8 or 2/16 is another DAC with DSP all in one box. but only targeted for active crossover i believe.
