Mahughes,
I strongly suggest that you not bother to try to entice Bill Feil into a rational argument. He's completely incapable of it. Why? Because he views his opinions as fact (regardless of disclaimer), and anyone who disagrees is automatically an audio idiot. I offer as evidence a recent 'discussion' with him, in which he claimed that my system 'sucks' (in spite of his never having heard the speakers, nor am I sure about what else he's not auditioned). Feil has opinions on everything, even on gear that he has never experienced.
There is no question in my mind that certain gear provides a greater 'jump factor', which I believe is largely due to dynamic capability i.e. the ability to swing from pp to ff quickly - just as live music does. Whether you call it PRAT - or Joe or Bob or Bill - is immaterial. The effect is there, and I believe that it's part and parcel of a better audio illusion.
