Does anyone know if it's possible to purchase individual official Marantz remote controls? I'm looking for a Marantz RC004PMCD remote, which are the same ones that come with the PM6007 or CD6007. I'm selling my 6007 amp, but still want to use that remote with my new Marantz amp. I want to purchase it separately if possible. I already checked eBay, and there's nothing.
