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.
Texas Instruments TPA6120 provides Superior Sound Quality with ultralow distortion and low noise.
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.
EarMen TR-Amp support Tidal Masters (MQA) playback from iPhones and Android smartphones. MQA's technology folds high-resolution files into smaller files that can be streamed on the go. As MQA Renderer, EarMen products complete the unfolding process, allowing music lovers to enjoy a wider selection of high-res music.
EaMen TR-Amp support Qobuz high-res playback from iPhones, Android smartphones, and MacOS and Windows computers. Qobuz streams and downloads music in bit-perfect FLAC, the most widely used format for mastering and archiving, at resolutions of up to 24-bit/192kHz. With TR-Amp, listeners can enjoy more than 40 million tracks in lossless 16-bit CD resolution and over 2 million hi-res files.
