Detailed Description

Enhanced Magnetic Efficiency

The ST-80 SE incorporates a larger bobbin and an increased number of coil windings, which results in improved magnetic efficiency. This design enhancement contributes to the transformer's ability to deliver more detailed audio reproduction, capturing subtle nuances and textures in the sound.

Advanced Electromagnetic Performance

The transformer features a permalloy core with additional layers, which further enhances its electromagnetic performance. The use of permalloy, a nickel-iron magnetic alloy known for its high magnetic permeability, helps in minimizing signal loss and maintaining signal integrity throughout the transformation process.

Magnetic Shielding and Noise Isolation

The ST-80 SE is encased in a magnetically shielded permalloy case, which is then housed within a 10mm thick aluminum cylinder. This robust construction effectively isolates the transformer from environmental noise and electromagnetic interference, ensuring a clean signal path. The aluminum casing, machined from a solid block, not only provides noise isolation but also contributes to the overall durability of the unit.

Dual Mono Design for Optimal Channel Separation

The ST-80 SE is designed as a pure dual mono model, meaning that each audio channel is handled separately. This design maximizes channel separation, resulting in a more precise stereo image and greater audio fidelity. The internal wiring is point-to-point, using Teflon-insulated, solid-core pure OFC copper wire plated with gold, further ensuring signal purity and transmission integrity.

High-Quality Connectors and Stability

The transformer is equipped with gold-plated RCA jacks that feature Teflon insulation, which reduces signal loss and maintains the integrity of the audio signal. The substantial weight of the unit, at 1.5 kg, ensures that it remains stable and securely in place, even when connected to heavy cables. This stability is crucial for minimizing vibrations that could otherwise introduce distortions into the audio signal.
