>>assessing talent in tennis is as subjective as assessing the merits of components and stereo systems<<
Really? I KNOW that Anna Kournikova is not as good a tennis player as Martina Navratilova because I KNOW that Anna has won no grand slam titles and I KNOW that Martina has won 59 (singles, doubles, mixed doubles) grand slam titles. That is not subjective.
The same can be said for audio components if you KNOW enough about them.
You should try it.
