I wonder.... is there such a difference???? I mean, say you have good headphones (e.g. HD 580/600 and/or Ety 4/6) and good source (iRiver 550, NEX ia and/or Audigy 2 Platinum), the music sounds good --- then people say this is not good enough, try an amp for say, $200 and the music will sound even better. Then here comes an amp for $1000 and now what? It will sound even better? Then there are amps for $10.000, will the music sound better again??? To where we can go????? (Note: I used word "good" not word "excellent"!) Not to mention same story with: try better headphones, try better source...
I really find it hard to believe that all this equipment can make such a difference, because it ALL DEPENDS on the music itself. Can a CD with relativelly well produced music hold such a quality that equipment can make such a difference??
E.g. we (our band over here) recorded a CD with our own music, to best of our studio abilities, but hey, it is how it is, how can a better amp, a better source or/and a better headphone make it better than it is in reallity from recording???? I mean, if we used mics for $500 instead mics for $5.000 how can a headphone/amp/source make that "poor" mic sound as good as those top quality/expensive mics?
I think your listening equipment can do nothing if the equipment for producing the music was not at least that good. I hope this sounds understandable. If not, please let me know, I will try to elaborate on it.
Or are you all here always taking for granted - by default, that we listen to the best of the world produced music? Even then, I still wonder about all this equipment and the possibilities of it to make it such a difference in sound quality when listening to the music....
