In a mid-fi setup I can't imagine that you would hear the slightest degradation, IF you both braid and solder, properly (and then insulate, of course, using shrink tubing or at least electrical tape). If you just braid, even if you did it well enough to assure good contact over an adequate surface area, integrity of the contact would likely degrade over time due to oxidation.
