Peter, your mistake cabinets look better than a normal person's best! I like contrast in things (like painted wheel centers with polished hoops---the American Racing Torq Thrust II comes to mind), so I would get a set of the nickel plated brass spikes that Dayton makes and Parts Express sells. They're 1/2" in diameter, and come in two lengths, about 5/8" and 1-1/4". Provided with both are 6mm threaded inserts that the spikes screw into, and four of the spikes would look great providing contrast (along with the similar-looking dustcap of the driver) to the beautiful wood cabinets. They have nice clean lines, elegant almost, and would continue the long vertical movement of your enclosure. $10.99/set of four. Silver screw heads, however, would look too busy, and would spoil the nice dustcap vs. black cone contrast.
