Picking up a PMD661, primarily for doing non-music vocals with booms & lavs. I've heard good things about the Oade Super Mod, but I'll be using a Sound Devices 302 mixer in front of the recorder most of the time. Is it worth doing the mod if using a mixer, and if so, is the Super mod the way to go? The primary mic will be a Sanken COS-11D XLR lav for film vocals. TIA.
