What are the benefits of relocating the power supply from inside a piece of gear and into it's own external box? Electrical interference reduction maybe? I've notice a number of really high-end preamps having this feature.
When I get my new Trident S40 preamp I'm wondering if it would make any difference at all to attempt a modification to it by making an external box any moving the power supply out of the rack enclosure? If so, would you just use an XLR for the power transfer cable between the supply and the preamp? Is it difficult?
