By popular request – iBasso Audio send DX300 and DX320 further down the tube with their balanced Nutube 4.4mm Amp14 amplifier card. Twister6 loved "fine-tubing" the sound!

Building on Amp13, and the clamour for a balanced version on the back of its success, iBasso have come up with another Nutube module capable of swinging twice as much output voltage for bigger Focal and Fostex headphones.

iBasso's DX3XX series is a great platform to launch a design as ambitious as Amp14, with its dedicated analog section battery and extra chassis space for an uncompromising audio circuit put to great use here.

Amp14 is the natural evolution for DX320, its strong liquidity and air the natural complement to one of Head-Fi's most detailed music players – despite its Nutube's cathode input providing strong immunity to Wi-Fi and external interference, in a reference implementation of Korg's direct-heated triode.

Product Description

Placed at the voltage gain stage where it will yield the biggest sonic impact, the small output of Amp14's Nutube then gets boosted by Toshiba FET buffers.

The differential stage begins there while preserving the square law function of the Nutube, and grants the voltage section enough juice to drive the rest of Amp14's solid-state output stage.

DX320's dynamic range is maintained through two NJR NJU72315 digitally-controlled analog volume parts. The fully balanced, differential, Amp14 is additionally able to count on common-mode rejection plus adequately applied negative feedback for more linearity and less distortion and noise.

The separate 2,000mAh analog battery aboard the DX3XX line supplies the backbone of power for Amp14's high operating voltages, with clean, individual DC power sections for crucial parts of the module including a 14 volt supply for the Nutube's anode.

Dual Texas Instruments OPA1622 op-amps make up Amp14's power stage with operating voltages of 8 volts, such that higher impedance transducers are given the swing necessary to perform. A dedicated 4.4mm line-out section on Amp14 also supplies DX320's excellent small signal to an outboard amplifier.

Such is expected of a high-performance iBasso Amp14 module that yields excellent distortion and noise specifications, while capturing the romance of tubes in DX320. ichos-reviews says Amp14 completes iBasso's family of amp cards with its natural timbre.
