Some more cup images. I know how you guys like the pictures. These cups were part of the first pair of "woodied" Grados that I purchased. They're obviously a bit smaller than the turned cups were seeing nowadays. However, I believe these were probably made by a user with a drill press and the edges were sanded to perform the round-over. I did a little renovation on the finish of the cups to refresh them a bit. They use standard Grado drivers that have been removed from the Grado cups. They are held in place by pressure only. All it takes is a small, single layer of black electrical tape around the plastic rim of the driver housing and one just gently pushes everything into place. These cups also have the notches in place for the cables, so one doesn't even need to de-solder and re-solder their drivers to get these babies to work.
My thoughts are to probably install my Alessandro MS-1i drivers into these as well as the Mogami cable and Neutrik connector and put 'em up for sale. It probably should be able to make someone who's interested in coming over to the dark side of the wood to venture into the world without too much coin. Unfortunately, the only flaw is that small area that is dented in on the outer rim of the cup. I bought the cups this way, so it's been there a while. However, they are beautiful and would be pretty compact for travel due to the smaller cup size.
Enjoy!
