a REMOTE idea?

I’ve been meaning to ask this for some time. Seen it asked before a couple years back but with no real answers.

Many of the better preamps and integrateds are designed without a remote volume control due to degradation of sonics… yada yada yada

does anyone know of a remote control device that’s commercially available or adaptable to be used separately from the component’s circuitry?
In other words, I’m thinking of a mechanical knob-turning device that can situate right next to the component’s volume control, clamp on or somehow install onto it with adjustments, whose sole function is simply to rotate the knob clockwise and counterclockwise via it’s own remote.

Alternatively, I don’t see why something can’t be installed internally, assuming there’s enough room.
The key here, I suppose, is to be completely separate circuit-wise as to not hinder the component’s sonic “purity.”

I did come across a post not long ago about someone using parts of a remote control toy car, and using the O-ring around the volume knob…
But I was thinking something a bit more refined. I’m also aware of Bent Audio, Welborne, and Placette products, but I’m after something different, more easily adaptable, and usable outside the box.

I gave it some thought and can picture several ideas, but…

Someone out there know of anything like this or have the brains and skills to build one?
I’m actually puzzled why something like this isn’t on the market… or is it?
