The Third Plug Noise Absorber: The Long-Awaited LAN Plug Type
The YUKIM SAA plug noise absorber series, starting with the PNA-RCA01, has garnered acclaim for its reliability and effectiveness, backed by evidence and the experiences of its users. By simply plugging it into audio equipment, it enhances the quality of sound and visuals, bringing them closer to their original essence. These devices have become increasingly popular overseas. The latest addition, the PNA-LAN01, is another product developed with the meticulous care of Mr. Masahiro Yamazaki. This new LAN plug type, highly requested by many audiophiles, is expected to be warmly welcomed. All PNA products undergo stringent listening tests conducted by Mr. Yamazaki before shipment.
Features and Concept of the PNA-LAN01
By inserting the PNA-LAN01 into a LAN terminal, it absorbs high-frequency noise within the device and acts as a conditioner to refine the original audio and visual signals.
Technical Details of the PNA-LAN01
- Absorbs noise components within the device using a resistor-capacitor series circuit.
- Uses “Pulshut” (an electromagnetic wave absorption sheet) to eliminate conductive noise in internal circuits.
- Features a low-impedance metallic case to absorb high-frequency noise and enhance virtual ground effects.
Effectiveness of the PNA-LAN01 (Audio Quality Improvements)
By reducing high-frequency noise within the device, the signal-to-noise ratio (S/N) improves, bringing out subtle sounds previously buried in noise. This enhances freshness, resolution, treble clarity, and bass extension, creating a broader and more three-dimensional soundstage. While the degree of effectiveness may vary depending on the environment, examples include:
- Improved S/N ratio.
- Stronger bass presence and clearer vocals.
- Rich three-dimensional sound.
- Improved separation of sound from speakers.
Key Features of the PNA-LAN01
Non-magnetic die-cast LAN (RJ45) terminal.
1.5mm thick, machined brass case (non-magnetic DR plating/copper-tin-zinc alloy plating).
No PCBs used; wired in free-air.
Gold-plated copper wiring (Φ0.7mm) from Amtrans without nickel plating underlayer.
Styroflex capacitors from British LCR.
High-quality AMRG resistors from Amtrans.
Electromagnetic wave absorption material Pulshut from Asahi Kasei.
Solder containing silver.
Complies with RoHS standards (using RoHS-compliant materials and parts).
Audio Design Philosophy (Message from the Developer)
The PNA series aims to reduce noise and bring out the natural vitality of your equipment and sound sources. While many accessories claim to reduce noise, they often come with side effects. The PNA series is carefully designed to avoid these issues.
One common side effect is the “death of sound,” where vitality, liveliness, and soul are lost. The PNA series reduces noise while preserving the energy and richness of sound. Another issue is that noise reduction often polishes away subtle audio signals, resulting in overly clean but emotionally dull music. To address this, the PNA series specifically targets high-frequency noise that negatively affects sound quality, with all design elements determined through listening tests.
