Yes Nando, Hitachi and Maxell were the same using same materials and technologies for making tapes, there's no correlation between models and the DL from Hitachi is infact the UD-I from Maxell speaking about the tapes, both very nice superfeerics anyway. I didn't saw that chrome, the UD-EX you have there but i'm sure it has a Maxell version loaded with that tape too,,, and it's not something new for Maxell as long they started with Hitachi and finished with RAKS
