You have no way of proving whether their opinion is biased or not and your own opinion of them possibly being biased could be claimed to be biased in itself. Besides, I said nothing about paying attention to what they said about the vinyl under review; my intention was for people to read what was said about the state of the master tapes, how the most recent mono and stereo mixes were made, etc. Also what comes to trusting the recommendations of people on audio forums, I stopped paying any attention to what critics of any kind – music, audio, or otherwise – have to say years ago, but the people who write their opinions on audio forums I have equally low faith in. So many people out there think they know what they are talking about, but sometimes don't have the faintest clue in actuality. How many times have I seen an absolutely horrible sounding album unironically named as the best sounding album someone has heard in their life? How many times have I seen a piece of audio gear recommended for all the wrong reasons? How many times have I seen one of the most mediocre albums I've heard in my life be named the album of the year? A surprising number of audiophiles don't even know what is the difference between mixing and mastering, let alone how a well-recorded album differs from a well-mastered one. Taking anything anyone says – on the Internet or otherwise, but especially on the Internet – with a grain of salt when it comes to sound is more than a healthy approach and ultimately the one you can trust the most (hopefully) is you yourself and your own ears. Others' opinions can be useful as reference points but no one should ever take someone else's opinion and blindly make it their own.
