Dac with DSP suggestions

I currently have a Schit GUNGNIR Multibit dac - which sounds great, and was wondering if I wanted to get a DSP unit with a Dac built in what the options are under $2,000 and ideally ones where software upgrades don’t require a Windows computer e.g can be done on a Mac.

Suggestions of great Dacs with DSP?
