EARMEN TR-AMP
EarMen, a co-brand of European manufacturer Auris
Audio that was established to market its portable high-end audio products, has released a battery-powered portable DAC/Headphone Amplifier/Preamplifier.
The new EarMen TR-Amp processes all PCM audio formats up to 32-bit/384kHz, DSD256 via DoP, native DSD128 and MQA with an ES9038Q2M SABRE DAC that uses ESS’s patented HyperStream II QUAD architecture and is equipped with that company’s Time Domain Jitter Eliminator.
The TR-Amp’s rechargeable 3700mA battery has a claimed operating life of 10 hours, during which time it provides sufficient power for the headphone amplifier section to deliver 400mW of power into16 ohms, but it is said to be able to drive almost all headphone design currently available. Charging is via a dedicated USB-C port, with data delivered via a separate USB-C data port.
The amplifier section of the TR-Amp uses a Texas Instruments TPA6120 IC with current-feedback ClassA/B amplifier architecture to ensure high bandwidth, extremely low noise and up to 128dB of dynamic range. “Using a current feedback amplifier means we can obtain a high-enough slew rate to eliminate odd-order distortion anomalies, plus deliver the current-on-demand at the output to enable the amplifier to respond quickly and linearly when necessary without distortion,” said Miroslav Milovanovic of EarMen. “It also means that the frequency response is gain-independent, which allows the full bandwidth of the amplifier to be used over a wide range of gain settings.”
Volume control is analog for both the preamplifier and headphone amplifier sections, and the TR-Amp has two headphone outputs that are able to be used simultaneously. “Play anything from MP3 to MQA, or stream from Tidal or Qubuz, you’ll always hear a beautiful, neutral sound quality,” said Milovanovic. “And no matter which headphones you connect, you’ll discover the TR-Amp delivers a performance level that will satisfy even the most demanding audio enthusiast.”
Available now for $US279 (including shipping), the EarMen TRAmp is designed, produced and assembled in Europe and comes standard with a shielded female USB-A to USB-C adaptor.
