Douk Audio Nobsound P6-Mini 6A2 Bluetooth 5.0 Vacuum Tube Preamp Speaker Receiver Stereo Preamp USB Player This is the "Douk Audio P6 Mini," a compact yet authentic vacuum tube amplifier. While many general small vacuum tube amplifiers only have the vacuum tube as a "decoration," this unit employs a Class A discrete circuit, and the vacuum tube is incorporated into the actual amplification stage. Therefore, you can fully enjoy the warm tone and rich mid-range expression. This model achieves both the soft sound spread unique to vacuum tubes and the driving force comparable to transistor amplifiers.
