No , I am not expert as said before many times in this forum.
If you talk to audiophiles and also listen to their audio systems (audio results) and try to experience many audio components in controlled condition then you reallize the most audiophile's ideas are just opinions not facts. Opinions are different to facts.
expert audiophiles are rare and you can hear the facts from them.
When I visited WBF for the first time I did not know David (@ddk) but after reading his posts I reallized he is different to other members.
Yes, there are people who have superior knowledge and experience. Karen Sumner is another example. I value their opinions and try to learn from them.
