While I can appreciate this sentiment, it's near impossible to demo some of the top end audio gear at a store. I live near San Francisco and you'd think there would be fantastic high end audio stores for this but there is maybe one total in all of the area and they're known for being scumbags who try to charge you $$ if you listen for more than 30 minutes and have plenty of awful reviews about how they treat you if you're not there to just buy buy buy.
I'd rather do my due diligence online, read through objective (measurements) and subjective reviews and take a gamble from there than deal with all that unfortunately.
