Based on the sixth generation of Nutube vacuum tubes made by Korg and Noritake, the iBasso AMP9 Nutube Vacuum Tube Amplifier Module completes voltage amplification through Nutube vacuum tubes, giving AMP9 an engaging and unique vacuum tube sound. On the buffer stage, buffers of up to +/- 200mA linear current output are utilized. The AMP9 has a high current drive capability for low impedance monitors and headphones, while giving a unique quality of tubes.
AMP9 uses many high precision Susumu metal film resistors, custom gold-plated inductors, ROHM polymer tantalum capacitors and Panasonic polymer tantalum capacitors to effectively reduce power supply resistance and improve dynamic performance and resolution.
A custom-made silicone shock absorber for the Nutube module, effectively reduces the microphonic effect.
Each AMP9 is tested and matched with the AP audio analyzer, with 3 multi-turn potentiometers. The three potentiometers are manually calibrated and matched by engineers for the optimal performance of the Nutube.
After 20 versions of development boards optimization and tuning, AMP9 brings a bright, sweet, and engaging sound, which is then brought to its full potential by our players.
