Product Description
Audiophile-Grade 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.
Japanese Shindengen 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 + 2 WIMA film capacitors
Effectively filters power supply noise to reveal a crystal-clear sonic foundation.
Monocrystalline 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 ensures that every nuance of the audio is faithfully preserved. With fully discrete voltage regulator circuit and high-precision reference, ultra-low noise and lightning-fast transient response are achieved all while effectively minimizing heat generation.
Relay-Switched 12V/15V Output, Precision Thermal Control
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.
Minimalist Aluminum Chassis, Aesthetics meets Performance
The device uses a 46W low-noise, low-frequency toroidal audio linear transformer. Toroidal transformers have innate advantages: the toroidal core made with non-oriented silicon steel strips provides high efficiency and low eddy current loss, while the corner-free coils result in a more uniform magnetic field and less leakage. Thanks to this power supply, your favourite DAC/AMP is fed clean power that allows it to produce pristine, immaculate sound.
