Cayin CP6 Electro tube Bluetooth digital turntable high-end audio player, decoding portable CD player

The military-grade NOS electronic tube antique cathode tube, the new sound of CP6, is equipped with two carefully selected paired American Raytheon JAN6418 tubes. It is a military-grade miniature direct-heated five-grid NOS vacuum tube. The left and right channels operate independently, forming a dual-channel A-class common-cathode amplification circuit. PO/LO/Bluetooth all support one-click switching among three tones. The entire machine adopts an exclusive 22V high-voltage low-noise LDO voltage regulator for power supply, combined with a DC filament design. This effectively filters out the power supply's background noise and hum, while maintaining high-resolution quality. It also imparts a warm and transparent musical quality, allowing antique tubes to present a completely new and pure sound.
