Also, if it doesn't resolve readily, I'd suggest giving Outlaw a call and getting some help from them.
Nothing changed in the system; I don't use any kind of IR repeaters; no obstructions blocking the front (stood 6" away and neither the OEM or Pronto would work on it). Pronto continues to work fine with all other components.
painttoad: I really like the clean sound of the MA-500s for full range. They don't add anything to the music and never sound like they're straining. With Klipsh speakers tending sometimes toward the bright side, the MA-500s, which lean slightly to a warmer sound, balance that out very nicely. Basically, they sound more like tube amps than transistors.
