So - not really suitable for 2.1 / 2.2 setups.
Bummer #2.
Well, you can use the 3/4 output as a Line-Out I believe, rather than for headphones. But it would get a little inelegant cable-wise I guess.

I run full range to the mains, and the sub's internal low-pass filter set to 56hz, which is what the ATC manual says.

Not using anything....

In theory you are right. That said I demo'd Dirac Live for a while with a near identical setup (only change was using my Audiolab MDAC, before I got the RME) and for me at least it still made a BIG positive difference. I just felt it was too expensive. That said I'm waiting for the new Dirac Live to come out and may re-evaluate. Or, if I find time, which is unlikely, I might play around with REW to create filters I can use in Roon.
