For hi fi equipment and cables reviews, it is beneficial for readers to know some form of benchmarking. For example, Audio Note 4N silver cables can offer faster sound and more analytical power than Sitech silver/gold cable or Taralab copper cables of the same price level. Comparison or benchmarking is a very important reference to readers.
If a user wants to improve analytical power/bass/treble/etc, he/she can make a suitable/sensible change to equipment and cables accordingly.
Most reviews just mention how good an equipment or cable is (e.g. 高音甜、中音準、低音勁). This is not very helpful because the readers would have no idea how sweet, how accurate or how powerful.
