“Not all those who wander are lost.”
If I had the time and means I'd churn through a bunch of gear just to have first hand experience with it. The only way to be absolutely sure is to try something in your room, with your music, with your ears. Since that is usually impractical it's necessary to vet your sources anytime you need to use second (or third) hand information. There are some great resources here and other places once you weed out the clueless yahoos, fanboys, and trolls. Professional reviewers don't get disparaged for equipment turnover. Some amateur reviewers are willing to patiently answer the endless stream of repetitive questions. With all the great equipment that is available sometimes there's only a very few people that have done a direct comparison with the two obscure components one of us is currently fixated on. I'm grateful for their input. I just wish it were easier to tell them apart from the yahoos.
