Based on the sixth generation of Nutube vacuum tubes made by Korg and noritake, AMP13 completes voltage amplification through Nutube vacuum tubes, giving AMP13 an engaging and unique tube sound. On the buffer stage, buffers of up to a ±200mA linear current output are utilized. The AMP13 has a high current drive capability for low impedance monitors and headphones, while giving a unique quality of tubes.
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.
Please update the firmware to the latest one to have an optimized support of the AMP13. And above all, please enjoy the music!
Output port: 3.5mm single ended
