Well, I'm glad some of you understand each other sometimes when using this kind of language. The only real attempt to define PRaT in this tread was made by Myles, and he simply substituted it for dynamic range. Can't say I see the point in that. Now if what you're talking about is that exaggerated treble response that some Naim equipment had when the term was created in the UK, I can certainly understand why one would invent a term for it. PRaT is infinitely more complimentary than what I'd call it.
