"Good music can't be delivered without good system..."
I cannot be in agreement with this statement. Good - and great - music stays good and great no matter how you hear it.
In the car, on cheap earbuds, through shopping center el-cheapo speakers, and of course, at home on our "expensive" systems.
Good music is about ENJOYMENT. Great gear can of course help, but it is not essential to the enjoyment of music - unless you love gear more than music - (here we go again!)
I once heard Brown Eyed Girl on Bourbon Street played through crappy speakers full blast in a bar. Man, the energy and the FEELING was incredible. Good music will be crappy sound most times over bad music and terrific sound - at least for me. Your pick, Satchmo over an old Marantz with PSB speakers or Lawrence Welk over a Boulder-Wilson 100k system? (no offence about the music).
