Midcable Power Regulation

[arnach]

Hello,

I have a preamp in a seperate enclosure from the power supply.

I've been drawing up the design for the power cable, and got to thinking:

Why not use a small box in the middle of the cable, in which there is an additional active regulator/regulation stage or just some capacitors?

I'd therefore have a regulation stage in the power supply, in the middle of the cable, and in the chassis of the pre-amp.

Supposing proper engineering was done to keep noise out, grounds intact, etc, ** What are the drawbacks?

Thanks,
