What to know before buying

The listing describes the cable as an Onix Series analogue stereo interconnect, but also calls it a digital coax cable and uses 75 ohm impedance and a 22 Gigabits Per Second transfer-rate entry. Confirm the intended connection and compatibility before buying. The CL2 rating is a listing claim, not independent verification.

Customer feedback is positive about sound quality, including one report that the cable helped eliminate hum. Feedback is mixed on whether the connectors make a solid, tight connection, and customers also describe the cable as stiff. These points matter for a six-foot RCA run where connector fit and routing flexibility affect installation. The listing's shielding and connector claims do not establish how it will perform in a particular setup.

Positive themes

Customers mention positive sound quality, with one reporting reduced hum.

Negative themes

Customers describe the cable as stiff and not flexible.

Mixed feedback

Connector experiences vary, with some reporting solid connections and others unable to get them tight.
