If your Super Magnum 99 uses 6SN7's, then it produces a more classic and lush tube sound than the newer Rogue preamps.
You don't say if you have the tube phono section, but the RP-1 uses a SS phono stage which is excellent. I think you'll have to decide between the features and more modern sound of the RP-1 to the sonics of the 99.
