Confusion about "high-end" racks

Hi,

I'm searching for a rack upgrade : finite master reference, grand prix audio monaco, sistrum, critical mass, audiav crystal or diamond series, silent running audio....
All use different approaches, different materials etc.. and usually criticize negatively one each other, especially I'm impressed reading comments from audiav about sra.
Is there specific experience, which is the most neutral - less coloured approach? what other parameters should consider?
