Cryogenic Treated Shuguang 12AX7 Vacuum Tube

The equipment undergone Cryogenic treatment, which is a process that involves exposing audio cables to extremely low temperatures, typically around -320°F (-195°C), to enhance its performance. This treatment improves audio quality and cable durability.

PROCESS:

The cryogenic treatment involves:

1. A slow, computer-controlled cool-down cycle from room temperature to liquid nitrogen temperature (-320°F).

2. Several temperature “plateaus” during the cooling process.

3. An extended “soak” period at the lowest temperature.

4. A controlled warm-up back to ambient temperature.

BENEFITS:

Proponents of cryogenic treatment improvements:

• Reduced sibilance in the lower treble range

• Increased soundstage depth

• Improved timbre and tonal accuracy of instruments and voices

• Enhanced rhythm and pace dynamics

• Better bass articulation, extension, and impact

• Overall reduction in noise and improved signal clarity

SCIENTIFIC EXPLANATION:

1. Molecular alignment: The extreme cold causes molecules in the metal to align in a more uniform, compact structure.

2. Crystal structure changes: The treatment may improve the crystal boundaries of conductors and affect the dielectric material.

3. Reduction of vacancies: The process decreases vacancies within the metallic structure, potentially lowering electrical artifacts or “noise”

SOUND QUALITY:

Natural Sound Reproduction: Many Shuguang tubes has warm midrange and natural timbres, making them suitable for genres like jazz and classical music

Versatility: Models like the Shuguang Black Treasure excel across various genres, from hard rock to orchestral music, offering a massive soundstage, tight bass, and detailed highs
