RIAA vs Columbia vs Decca


Ok, dumb question. I recently was lucky enough to purchase an ARC Ref Phono 2 SE. It has Options to select RIAA, Columbia and Decca equalization curves.

I realize that most 'modern' recording use RIAA, but when I purchase reissued, remastered pressings of old classical or jazz recordings that were on Columbia or Decca, should I use the corresponding EQ curves, or is that applicable to only the original pressings?

Does anyone know of a switchable unit which can fit, say in between a phono stage and a line amplifier, to enable switching between these curves? (I have an Aesthetix phono stage feeding an Audio Research line preamp...)
Or is there an equalisation circuit that anyone knows of which can be adapted for this purpose?
