Is there a place people can rank gear based on true sound quality (it's ability to resolve details and separation), and the synergy (ether by true ability to resolve detail and perceived listening pleasure)?

You mean a site like ranker.com where people can vote on a master list? I don't think so. But that would be pretty pointless, in my opinion, because it would ultimately only gauge how popular something is and wouldn't be a reliable indicator of which equipment is the highest fidelity. For that, you'll need to pay attention to more experienced audiophiles who publish comparisons between some of the best headphones and so on. The Battle Of The Flagships thread is a notable example. The Head Gear section also has rankings, but again, it's mainly just going to tell you which ones are more popular.
