It has been my experience that EN will give a warmer color and when compared to chrome, it seems to almost have a yellow tint to it. The plating can be very bright and reflective depending on the amount of etching of the part prior to plating. If the part is highly polished first, it can be plated with retension of this polish.
Since EN is electrically conductive, there is no need for concern of breaking through the film to establish the ground path in the battery tube; as is the case for anodized parts. I had a few Aleph parts EN plated and toyed with bead blasting some parts with masking to go for the contrast in surface texture. As it is, there are enough worms crawling around with the options in anodized parts. /ubbthreads/images/graemlins/icon15.gif
If you are after a matte finish, the part either needs extended etching or bead blasting, IMHO.
