As long as there have been humans, there has been music. This says to me that music is not entertainment (although it certainly is entertaining): it is essential.
Some of my earliest memories are that of sitting in front of an ancient 78 player, playing a stack of 78s. I was probably 3 at the time. My home was always filled with music as I was growing up, fed by a tiny 3-tube stereo combo, with which I was fascinated.
Other audiophiles and I do compare notes on equipment- there is a desire to get as close to the music as possible. I have used live performance as a measure- since all performance spaces and recordings are different, I had musicians play live in my house so that I could use direct mic feeds as part of the reference process.
Not finding what I wanted in the state of the art at the time, I started building my own circuits, which I have been doing ever since.
Its funny, I play bass, keyboards (myspace.com/thunderboltpagoda also myspace.com/salubriousinvertebrae) and flute; in orchestras, jazz, blues and rock bands, yet still the desire to surround myself with music persists. I enjoy all aspects of the art of playback, the quality of the packaging, the placement of music in the space of the recording, the strengths of the musicians and the weaknesses too.
Equipment comparisons wind up being common, but like a car, motorbike or camera, much depends on where you go/what you do with it, and it always better when the equipment isn't hindering the experience.
