Interesting, but I still won't buy a non-remote pre, and don't
understand why a remote motor can't be installed without affecting the
sonics.
There are volume controls that have a motor attached that do not affect sonics. The first two that come to mind are Aesthetix IO and Allnic L3000.
I owned both and in the case of the Aesthetix it is EXACTLY the same unit either way. The remote control motor can be added or removed and the original stepped attenuator remains the same.

The most likely answer I guess is that no OEM maker yet produces an
entirely neutral motorized volume control. Possibly Accuphase, Luxman
and so on do – but if they did they certainly wouldn’t supply outsiders.
Exceptions noted above and likely other Audiogon members can think of other examples.
