iBasso PB5 Osprey, Portable Tube Headphone Amp (PB5)
Dual Nutube 6P1 Vacuum Tubes
Manufactured by KORG and Noritake, the 6th Gen Nutube operates exactly as a conventional triode vacuum tube and creates the same characteristic rich overtones that are sought after in triode tubes. At the same time, Nutube achieves substantial power savings, miniaturization, and quality improvements when compared with many conventional vacuum tubes.
Voltage amplification is achieved with the Nutube, which results in a captivating and distinctive vacuum tube sound, all while maintaining exceptional linearity.
