Which DACs bypass digital filtering?

In light of above, no DAC eschews output filtering

 

Typically if a DAC accepts DSD256,512 its going to be very difficult to realtime filter that signal! so I'd assume there's no input filtering, but if there is, someones done a great engineering job  

 

Any DAC that does input upsampling does input filtering.

DSD256 and above allow more effective use analog filter. Because, noise pushed more far, than for DSD64/128.

I suppose any DSD DAC have no digital filter, because filtering in DSD form is impossible.

However, theoretically, there may be applied oversampling DSD for better work with analog filter.
