Texas Instrumets headphone amplifier

TR-Amp headphone amp use Texas Instruments High Fidelity TPA6120 chip and allows music, not the amplifier, to be heard. TPA6120 current-feedback AB amplifier architecture delivers high bandwidth, extremely low noise, and up to 128dB of dynamic range

Three key features make current-feedback amplifiers outstanding for audio. The first feature is the high slew rate that prevents odd order distortion anomalies. The second feature is current-on-demand at the output that enables the amplifier to respond quickly and linearly when necessary without risk of output distortion. When large amounts of output power are suddenly needed, the amplifier can respond extremely quickly without raising the noise floor of the system and degrading the signal-to-noise ratio. The third feature is the gain-independent frequency response that allows the full bandwidth of the amplifier to be used over a wide range of gain settings.

No Noise

Using a Super LOW ESR tantal capacitors, high grade components in power-supply design and 4 layer golden plated PCB technology from PC and smart phone industry we reduced the noise to minimum. This will improve super fine details especially in Hi-Res files where you can feel and hear the difference. 

CNC aluminum milled enclosure

TR-Amp is robust and solid. Enclosure is made from high grade alumnum
