Below are excerpts from the review:
When it came to testing this cable, it was initially catching dust. I could not be, pardon, arsed, to tell you how good or bad it sounded. But one fine evening, I ripped the CEMA RX series cable off my LETSHUOER EJ07M iems, and plugged the M120A in. First: it really upgrades these >$600 in terms of haptic and appearance. Second, the M120A is haptically a pleasure. And third, I liked listening to it.
Using the iPhone SE (1st gen.) with the AudioQuest DragonFly Cobalt, my latest “Deutsche Grammophon” classical music acquisitions sounded full and balanced. Whether this is better than the CEMA cable is completely irrelevant for you, everybody has to test a cable with their own equipment. All I can say is that I really like using this cable, and that I am positively surprised.
