While I am familiar with the premise that the ratio of equipment to music media once was the measure to determine your audiophileness vs. musicloverness. And I'm sure I've done the calculation. But there are so many holes in this assertion, even with traditional music media. Today streaming music throws another wrinkle into the formula.
Thinking on this a bit, I am not really sure why it is necessary to quantify and define one's standing. But if one is curious how about comparing the system value vs. the number of hours per month one listens to music — I dont only mean dedicated listening, it could just be playing in the background. I think this ratio is more telling. But honestly all you need to know how much music you listen to, just ask your spouse, friends, or neighbors!
