I have found two possible options for a budget preamp:

1) Topping L30 Headamp / preamp - 139 eur.


2) Pro-Ject Pre Box S2 preamp - 238 eur.


Topping seems to have some great specs, but the Pro-Ject is one of the very few with a remote.
It also has a fixed out for a headphone amp.
So if I don't find something new, I think this is the way.
