In response to the rapidly evolving landscape of portable audio technology, Brise Audio proudly introduces WATATSUMI, our next-generation reference portable amplifier. Designed to meet the demanding needs of audiophiles and professionals alike, WATATSUMI sets a new standard in sound quality, power, and versatility.
Building on a Legacy, From TSURANAGI to WATATSUMI
The journey began with the development of the TSURANAGI, originally created as a reference evaluation environment for cable development. This portable amplifier was engineered with a focus on maintaining high-fidelity sound without becoming a bottleneck for cable performance. It featured 4.4mm balanced input and output connectors a standard that has since become mainstream in portable audio.
Over four years have passed since TSURANAGI’s debut, during which time Brise Audio has expanded its cable lineup to include innovative models such as SHIROGANE, using pure silver conductors, and OROCHI, which incorporates larger conductor volumes for enhanced sound.
Adapting to Modern Audio Demands
The high-end earphone market has experienced significant growth, particularly with the rise of low-impedance earphones that demand low-noise amplification. Simultaneously, high-end headphones requiring substantial power have become increasingly popular, necessitating amplifiers capable of delivering high output levels.
Recognizing these trends, Brise Audio developed WATATSUMI to redefine our high-end cable evaluation environment, ensuring compatibility with a broad spectrum of modern audio components.
Innovative Design and Performance Enhancements
WATATSUMI inherits the core philosophy of TSURANAGI but elevates it through comprehensive redesign and technological advancements:
- Circuitry Overhaul: The entire circuit was redesigned from scratch, integrating the BIS2.0 low-noise input stage, previously utilized in our FUGAKU amplifier, to ensure ultra-clean signal processing.
- Power Output: The output stage was upgraded to BOS1.5, boosting maximum output to over 2000mW + 2000mW at 16Ω, approximately three times higher than its predecessor, enabling effortless drive for demanding headphones.
- Optimized PCB Layout: Leveraging years of expertise, the PCB layout was fundamentally optimized for superior signal integrity and stability.
- Enhanced Power Supply: The BPS1.5 power supply circuit offers more stable voltage regulation, contributing to deeper, more grounded bass and improved low-frequency reproduction.
- Premium Internal Wiring: The internal wiring now employs pure silver wire with a conductor volume exceeding that of SHIROGANE, ensuring superior sound transfer and clarity.
- High-Quality Components: All electronic components have been carefully selected and processed to deliver high-fidelity sound and compatibility with a wide array of cables and audio sources.
