Yes. But you can often evaluate the posters experience and values through their post(s) / virtual systems. People trying to be helpful will usually provide enough context for you to understand where they are coming from and their experience… and they creat virtual systems. But you are correct, just like any thing, you must read critically.
Seek advice on forums but always listen to your own ears!
I’m starting this thread because in our hobby there are no absolutes. You as an audiophile will bring a different experience. You will have different equipment, speakers,room, experience level and level of equipment. Be careful seek the advice but you never know who is giving it to you. Trust your ears not random measurements from random people. Some folks are not who they say they are.
