IWISTAO HIFI Hybrid Vacuum Tube Headphone Amplifier ClassA SE 6N11 Plus FET 8-600 Ohms 15 Times Gain High Current Power AKG K701
Model No: WHF-PREA6N11MOS
This headphone preamplifier, designed with a hybrid vacuum tube and field-effect transistor (FET) architecture, delivers a warm, engaging sonic signature and robust driving capability. It's perfectly suited for headphones ranging from 8 to 600 ohms, effortlessly powering even demanding planar magnetic models. The rich tapestry of even-order harmonics imparts a distinct, pleasingly classic tube warmth, captivating the listener. Employing premium-grade components, including a precision-machined aluminum alloy chassis, a high-efficiency 50W potted toroidal transformer, substantial 15000uF main filter capacitors, and a carefully selected 6N11 tube and high-power FET output stage.
Outputs of this headphone amplifier including to standard and high-power output.
The standard power headphone output offers a versatile connection for a wide range of dynamic and balanced armature headphones, providing a balanced and detailed listening experience. While suitable for most conventional headphones, this output is not optimized for highly sensitive in-ear monitors (IEMs). The increased power delivery may result in an excessively loud output, even at low volume settings, potentially causing discomfort or damage to the delicate drivers of IEMs. Therefore, it is strongly advised to use this output with caution, paying close attention to the volume level and gradually increasing it to a comfortable listening level. Prior to connection, it is best practice to ensure the volume is set to its lowest position.
The high-power headphone output stage is meticulously engineered to deliver substantial current and voltage, making it ideally suited for driving power-hungry, low-impedance, and low-sensitivity headphones, particularly planar magnetic designs. This robust output also provides ample headroom for high-impedance headphones, such as the AKG K701, allowing users to tailor their listening experience to their individual sonic preferences. Whether you favor the dynamic punch of planar magnetics or the refined detail of high-impedance models, this amplifier ensures optimal performance.
