My digital playback has always sounded fine to me, I can still hear past 17k. I have probably listened to about 200 different DACs in my life and never had a single issue with any of them but one, and couldn't be bothered to tell one from another. I have only done one shootout with DACs, one a from a 1994 Panasonic MASH cd changer and a megabux Classe CD player and DAC. We had 2 copies of the same CD for proper to A/B, and sonically we couldn't tell them apart.
Output filters are still output stage, they don't count against a DAC chip which is why I brought up that the majority of the differences in a DAC, standalone or integrated, lay with the downstream components, which if competently designed, won't ruin anything.
The only DAC that I've heard that was different from the rest was one in a Lennox Sound brand diskman from 199X that said it had 4X oversampling. It was grainy. But it was supposed to be cheap crap.
