【Important Notice for International Buyers – Tomoayax Premium Audio Hi-Fi Japan】
■ Voltage Compatibility
This product is designed exclusively for use in Japan (AC 100V, 50/60Hz).
Many regions use 120V or 220–240V.
Using this product without a proper transformer in such voltage environments may result in malfunction, overheating, or serious and irreversible damage.
■ Plug Type
This product uses a Japanese plug (Type A or B).
A plug adapter may be required depending on your region.
■ Transformer Requirement (Very Important)
A transformer is required for safe use.
A plug adapter only changes the plug shape and DOES NOT convert voltage.
Using this product without a transformer may cause serious and irreversible damage.
■ Buyer Responsibility
As this is high-end audio equipment, the buyer is fully responsible for confirming compatibility with their local voltage (100V / 120V / 220–240V) and usage environment before purchase.
■ No Return / No Refund Policy
We do NOT accept returns or refunds for:
・Voltage mismatch (including 120V and 220–240V environments)
・Use without a transformer
・Plug incompatibility
・Damage caused by improper setup or usage
■ Liability
We are not responsible for any damage, malfunction, or performance issues caused by improper use or incorrect voltage conditions.
■ Final Notice
Please ensure full understanding of the above before purchasing.
Use only under the correct voltage environment.
Sound quality innovation through new technology: This product is an advanced model of Nobsound's vacuum tube technology. Developed based on the proven track record of the NS-08E, which is supported by many users, it enhances the expressiveness of vocals and string instruments. It neutralizes the coldness characteristic of digital sound sources and enhances immersion when listening to soft music and classical music. For example, when enjoying light music with earphones while working in the office, harsh high frequencies are smoothed out, contributing to maintaining concentration. With a circuit design that minimizes background noise, it achieves clear playback even in quiet environments, providing a stress-free experience.
Warm Sound Output: By incorporating vacuum tubes, the harshness of digital sound can be flexibly adjusted. For example, when watching movies in your living room at home, the clarity of dialogue and the depth of background music are improved, enriching family time. The warm and soft sound quality also has the effect of reducing ear fatigue from prolonged headphone use. Designed with a wide frequency response, it supports a wide range of genres, from vocal music to instrumental music, allowing you to experience a spacious sound field in various everyday situations.
Customizable Compatibility: Equipped with treble, bass, and volume adjustment functions, allowing for easy tuning to your preferred sound profile. The vacuum tubes are easily interchangeable with multiple types such as 6x1 and 6AK5, providing flexibility for hobbyists who build their own audio equipment to experiment with tonal variations using different tubes. Optimization is possible for specific uses, such as monitoring environments in music production studios or podcast listening. Addressing pain points such as incompatibility with existing systems, it enables cost-effective upgrades.
Compact Design for Convenience: This vacuum tube preamplifier is one of the smallest in the world, making it ideal for small desk spaces and portability. Combine it with a laptop or portable player to create a high-quality sound environment even when you're on the go. For example, using it as an earphone amplifier while working in a cafe allows you to immerse yourself in music without being bothered by surrounding noise, improving your work efficiency. Its lightweight body (205g) makes it easy to store, expanding its uses as an entertainment device for travel and business trips.
Enhanced sound quality through high-voltage circuitry: The Class A amplification circuit employing a 6J1 vacuum tube achieves a voltage amplification ratio of 1.5 to 2.0 times. For example, when connected to a home theater system for movie viewing, the dynamic range is expanded, reproducing the impact of action scenes without loss of power. It boasts high compatibility with almost all subsequent amplifiers, and when combined with a DAC or active speakers, it complements the "thin" texture of digital sound sources. Designed for everyday listening, it achieves both transparency in the mid-range and crispness in the bass, bringing out the emotional depth of the music.
