Description

This circuit is designed with reference to imported high-end machine schematics. It features a premium double-sided thickened gold-plated PCB (substrate thickness: 2MM, copper foil thickness: 75U, far superior to standard 30U). The dual-channel design incorporates independent MOSFET-regulated power supplies for each channel (with completely separate ground lines for the left and right channels, achieving higher channel separation). Filtering utilizes brand-new Nippon Chemi-Con electrolytic capacitors. The audio amplification stage employs brand-new American high-fidelity MOSFETs (IRF610/9610) for output, paired with brand-new Taiwanese Bonic/YONTEX MKP axial coupling capacitors. Resistors are from the military-grade Factory 718 (the same manufacturer that supplied resistors for the Shenzhou-6 spacecraft program). To overcome the common drawbacks of traditional potentiometer-based volume control—such as low reliability, contact sliding noise, reduced dynamics, and narrowed frequency response at low volumes—this preamp uses a relay-switching system for volume control. This allows for convenient volume adjustment. It eliminates the need for an external volume board, shortens the signal path in the music channel, and contributes to improved sound quality. The pure resistive circuit ensures higher fidelity—far superior to traditional potentiometers! The entire unit operates in single-ended Class A, delivering a sound that is delicate, vivid, smooth, and rich with musicality, along with exceptional musical resolution. The tonal character is as brilliant as gold—noble, ethereal, beautiful as heavenly music, and as mellow as Maotai liquor. It is extremely listenable and surpasses ordinary tube preamps. This represents exceptional value for a preamplifier.
