75W Toroidal Transformer

Specifically designed for low-noise audio, this toroidal transformer utilizes a grain-oriented silicon steel circular core process for higher efficiency and minimized eddy currents. The seamless, fold-free coil design ensures a uniform magnetic field and minimal magnetic leakage. With a 75W reserve, it effortlessly handles high-dynamic transient demands, delivering solid bass extension and a vividly clear soundstage.

Audiophile-Grade Components

Japanese Shinengen D15XB60 Bridge Rectifier
Low heat generation and high stability minimizes micro-interference caused by current fluctuations for a cleaner audio signal.

5 ELNA Capacitors + 7 Rubycon Filter Capacitors
Effectively filters power supply noise to reveal a crystal-clear sonic foundation.

Mono-Crystalline Silver-Plated Copper DC Cable
Reduces transmission loss and shields against electromagnetic interference (EMI) to enhance audio details.

Fully Discrete NMOS Voltage Regulator Circuit

Dual high-current IRFZ34NPBF MOSFETs are used in a parallel configuration to lower internal resistance. The result is improved dynamic range and assurance that every nuance of audio is faithfully preserved.

Relay-Switched 12V/15V Output

An integrated relay manages the transformer's output voltage to provide a precise match for both 12V and 15V settings. Such a design maximizes power efficiency and significantly reduces heat generation during operation.
