R500 are fine speakers I can't deny that, that is the reason I have them. But Phil's have those mid\/high range elements with well engineered crossover that I believe will produce more open sound than R500. Of course I haven't heard the Phil's and can't really say how they sound for comparison.\n\nThe Phils are truly great speakers, the RAAL, crossover, and open back mid produce a sound a spaciousness that most speaker's can't match anywhere near their price range. However, they're not magic and how they sound is heavily dependent on the room, placement, and the source content which Dennis mentioned above. I'm not saying they're not great, I own them, but tempered expectations should be had. Especially when comparing against a very capable speaker like the R500's.
