Below are excerpts from the review:
High tones: In this area, we will definitely notice an increase in resolution and more air. It is worth noting that the ddHIFI RC30B perfectly controls the upper frequency range, offering a clean and not flashy sound. Which is a very good result and the ddHIFI team deserves great praise for it. Because excessive high tones are a common problem with silver cables. I am all the more glad that the ddHIFI RC30B does not have this ailment.
