A catch 22 question as both are important. We probably all fell in love with music first as that is what communicated to us and continues to touch us in a deep way. Then we were exposed to that music being played on a HiFi set up and what grabbed us was how great the music sounded and what detail we had been missing on the radio or a more modest music system. With music my friends phrase 'too much music too little time' springs to mind as I continue to seek out new artists, but at the same time sound is key too. So I'm going to cheat, and say I put both first, it's not an either, or - but both that deliver me enjoyment.
