Know before you buy
The Pure Harmony uses ultra-high purity silver conductors with a 106% IACS conductivity rating, which is significantly higher than standard brass or gold-plated connectors. It also features a unique star-point grounding design to minimize eddy current distortions for a cleaner signal path.
Not at all. The pins are designed with a tag-shaped profile, which makes it much easier to attach and solder various wire types compared to traditional cup-style connectors.
The housing is held in place by two integrated screws. This dual-screw system provides a robust mechanical grip, ensuring your cable remains securely attached and protected from strain.
Yes, they are engineered for a secure, snap-like fit. This ensures a consistent, high-pressure contact with your RCA sockets, which helps maintain signal integrity and prevents accidental disconnection.
The anti-short shield provides a physical barrier between the signal and ground pins. This design choice helps minimize capacitive and inductive interference, keeping your audio signal as pure as possible.
