... so theoretically the term audiophile doesn't fit when talking about people of type II, III and IV. But practically (or necessarily?) the term has on the one hand expanded to something like "anyone with an above-average interest in audio equipment" and on the other hand has an imo a negative connotation. Something like this:
The latter being the reason why I prefer the term hi-fi enthusiast and on a related note music lover.
By definition, any high end system "should" sound alike. Any ampiflier, cable, player that have their own unique signal are not "high" fidelity no matter how much they cost. The co;or/difference some people crave are is really acoustic photoshop or equivalent to soft focus lens. Personally, I do prefer the term portable audio enthusiast. For I can enjoy my music on my car stereo, Sansa/Ipod or my home stereo as long as they're good music. I no longer enjoy the direct to disc stuff that sounds good sonicly but not musically. And I DO enjoy live concert, And every time I went to a concert, I have the urge to upgrade. I don't know what category does that put me in.
