iBasso AMP13

The iBasso AMP13 is an interchangeable amplifier module for the iBasso DX300 and DX320 digital audio players, the first AMP module to feature the 6th generation Korg Nutube vacuum tube, bringing genuine tube-like character to your DAP without sacrificing the background noise floor that defines top-tier portable playback. Three-channel amplification, dual 3.5mm outputs, and the Nutube's characteristic warm, smooth harmonic enrichment make the AMP13 one of the most distinctive amp modules in the iBasso ecosystem.

Type and Technology

Interchangeable amplifier module for iBasso DX300 and DX320 DAPs. 6th generation Korg Nutube 6P1, a miniature vacuum triode that operates on the same principles as a conventional triode tube, providing voltage amplification with the warm, smooth harmonic character of tube amplification at a fraction of the power consumption and physical footprint. Three-channel amplification architecture: Nutube 6P1 handles left and right channel voltage amplification, while an OPA1622 op-amp provides ground-channel current amplification, a design that achieves the tonal character of tube amplification alongside a dramatically reduced noise floor. Current amplification stage follows the Nutube for clean, precise, detailed signal output. Toshiba 2SK209 field-effect transistors as signal output buffers, inherited from the AMP9 module. Separated signal grounding and shield grounds for noise prevention. Uses the independent amplifier power section of the DX300/DX320 for maximum performance. Dual 3.5mm single-ended headphone outputs for simultaneous two-headphone connection.

Sound Character

The AMP13 gives the DX300/DX320 a warm, lush, and tonally rich character distinct from the solid-state AMP modules, the Nutube's harmonic enrichment adds body and dimensionality to the sound without the background noise or power demands of a conventional tube. A compelling alternative to the standard solid-state AMP modules for listeners who prefer a tube presentation on the go.

Compatibility

Compatible with iBasso DX300 and DX320 only. Not compatible with other iBasso DAP models.
