What matters to me is whether I'm moved by my system.
I’ve had friends with far more costly rigs. They sounded very nice but didn’t actually draw me into the music any more deeply than mine.
I don’t know how you can compare subjective listening experiences, let alone rate them, especially given that dfferent guys prioritize different aspects of said experience.
Sure, you can do it based on dollars spent. Not anything I’m interested in spending time doing, but as they say, "different strokes".
And how do you account for the fact that spending more doesn’t guarantee better sound?
