The AMP9 Korg Vacuum Nutube AMP Card from iBasso is specifically designed to be used with iBasso's DX150, DX200, and DX220 digital audio player. The AMP9 utilizes a high current drive and sixth generation Nutube vacuum tubes by Korg and Noritake. Together they are ideal for playback through low impedance monitors and headphones, all while providing the unique sound vacuum tubes offer.
High-Quality Parts for Hi-End Sound
The AMP9 is engineered with components that effectively reduce power supply resistance and improve dynamic performance and resolution. The components include Susumu metal film resistors, custom gold-plated inductors, ROHM polymer tantalum capacitors, and Panasonic polymer tantalum capacitors.
