Since a phono preamp is now to be a feature of the Model 978, and if it's not too late, I'd like to see said phono preamp include a (switchable) infrasonic filter, say -3 dB at 15 Hz with a 3rd order roll-off, like the one on my old Apt/Holman preamp, a tour-de-force design "back in the day". IIRC, a similar filter was also part of the phono preamp topologies of early "classic" NAD receivers, as PeterT will surely remember.
