iBasso AMP13 KORG Nutube Module for DX320 / DX300

6TH GEN KORG NUTUBE AN ENGAGING, UNIQUE VACUUM TUBE SOUND
Provided 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, the Nutube achieve substantial power saving, miniaturization, and quality improvements when compared with a conventional vacuum tube.

The AMP13 competes voltage amplification through the vacuum Nutube, while giving AMP13 An Engaging, Unique Vacuum Tube Sound, delivering excellent linearity.

3.5MM+3.5MM
Low Noise Tube Output + Maximized Output Unique Dual Single Ended Outputs

LOW NOISE TUBE OUTPUT
The AMP13 utilizes Nutube 6P1 as a voltage amplifier. This is followed by a digital volume control and current amplification. The low noise tube output is the output after the first stage of amplification. Although the output is not high using this design, the Nutube has a stronger tube sound signature and noise control is excellent. (2.5Vrms)

MAXIMIZED OUTPUT
The output passes through a first stage Nutube amplifier, followed by a secondary amplification. With this, the AMP13 has a higher voltage and current output capability, that is, a better driving capability for headphones and IEMs. (4.1Vrms)

HAND MATCHED SO THAT EVERY ONE IS A MASTERPIECE
Each AMP13 is tested and matched with an AP audio analyzer, with 3 multi-turn potentiometers on the AMP13 board, which are manually calibrated and matched by engineers to present the optimal performance of the Nutube.

AMP13 is compatible with the DX320/DX300. Please update the firmware to the latest version to have an optimized support of the AMP13.
