FX-AUDIO- PH-A2J TPA6120-equipped current-feedback Hi-Fi headphone amplifier (black)

A new high-quality headphone amplifier with two analog inputs has been released from the FX-AUDIO- brand.

Equipped with the TPA6120 current-feedback high-impedance headphone amplifier IC, it delivers power and high sound quality that can easily drive even high-impedance headphones!

Enjoy the delicate expression and powerful drive of the TPA6120 headphone amplifier IC, which was well-received in the DAC-X6J, with analog input.

Renewed to the 3rd production lot, available from January 28, 2022. *Changes in the 3rd production lot:

◆Change in output filter resistor components The resistor components in the output filter section have been changed from DALE (1% precision) to 0.1% high-precision resistor components.

The adoption of high-precision components has reduced the output error value of the left and right channels, resulting in improved sound quality, especially improved localization.

◆Change in operational amplifier The operational amplifier in the gain adjustment/buffer circuit section has been changed from "OPA2604" to "LM4562".

The LM4562, known for its high resolution and clear, transparent sound reproduction, excels at modern audio reproduction and actually uses the same circuit as the discontinued and now highly sought-after LME49720. Based on user feedback, we've shifted the character from the richer sound of the OPA2604 to the high-resolution, clear sound of the LM4562. It also pairs perfectly with the TPA6120 headphone amplifier IC. Enjoy high-resolution, clear, and refreshing sound.
