We have discussed it several times.

It's neither about XMOS nor about AK4559.

If a DAC manufacturer introduces passive filters inside the DAC - e.g. in front of the XMOS - you might compromise the bits/packets by overfiltering with another filter.
With a passive filter (e.g. Jitterbug/iPurfier) this will happen much earlier then with e.g. the Regen.

The same might happen if the bits are already quite compromised due to e.g. poorly implemented interfaces (incl. poor power situation) on the PC side, poor connectors or cables.

I'd guess if you'd put the Regen - as active filter - in between even the
Jitterbug can stay in your setup.

I'm sure in the (near) future we'll see more DACs coming up with the filters inside. Hopefully these manufacturers are going to introduce, beside proper noise and HF filtering, hub chips/regenerators to get things right.
Would be nice if XMOS would introduce a new generation of chips/solutions which copes with the entire subject.
