In my own experience, reading reviews that don't include measurements are mainly for entertainment, except for those reviewed by a group of people that may help you rule out those that the majority thought were bad, especially when the reviews were done "blind".
In a Harman study, a group of screened/selected people actually rated a $700 sub/sat speaker system higher than a $4,000 one when they did not know which one they were listening to. In sighted tests, the $4,000 one sounded much better to them.
So I suggest you focus on mainly reviews that include measurements first to come up with a short list, and then do you listening test. 6K for a pair is a decent budget, but still large enough amount that warrants some research and do both objective and "subjective measurements".
