I have two complaints about the Audiogon forums, or more accurately about the people who post here.
First, there are too many people who post emphatic, seemingly authoritative comments who do not have actual first-hand experience to back up their opinions. Too often comments really boil down to “I have the XYZ amp and I really like it, therefore it is the best.”
Second, there are too many people who offer pseudo-technical explanations for what they hear when they don’t have the engineering knowledge necessary to draw those conclusions. Some examples: all attempts to explain why cables sound different from each other; all attempts to explain why one type of mounting platform or footer sounds different from another type; and comments that attribute a component’s sound to one or more measurements which usually is just parroting the manufacturer’s claims.
The Steve Hoffman equipment forum is hardly perfect but it has more diverse opinions and there is a higher percentage of posters with in-depth experience than at Audiogon. For example there are some threads at SH forum on Audio Note gear that are simply the best resource I know of regarding AN equipment.
