Product information

Description

The InLine AmpUSB-EQ Hi-Res AUDIO HiFi DSD USB Audio DAC and headphone amplifier is engineered to elevate your listening experience by bridging digital sources with high-performance analog output. Featuring an integrated 12AU7 tube and a robust digital-to-analog converter, this unit delivers exceptional clarity, depth, and warmth for your favorite tracks. Built with a durable metal housing in a sleek black finish, it fits effortlessly into any desktop audio setup while providing versatile connectivity for various audio gear.

Advantages

This audio device stands out through its support for high-resolution audio formats, offering detailed playback up to 384 kHz/32 bit and native or DoP DSD 2.8/5.6 MHz support. The inclusion of a 12AU7 vacuum tube combined with a hardware 3-band equalizer allows users to precisely tune treble, mid, and bass frequencies to match personal preferences or specific acoustic environments. Furthermore, asynchronous USB mode and an integrated de-pop function ensure stable, low-noise signal processing, while the versatile input and output options accommodate a wide range of playback and recording tasks.

Suitable for

  • Connecting high-impedance headphones ranging from 16 to 600 Ohm
  • Enhancing desktop computer audio with high-resolution digital-to-analog conversion
  • Digitizing analog audio collections such as vinyl records and cassettes via line-in and phono inputs
  • Fine-tuning sound output using the hardware 3-band equalizer and 12AU7 tube stage

The device may not be suitable for users who exclusively rely on modern mobile operating systems or plug-and-play environments without driver support, as it is primarily designed for Windows and Mac OS X setups. Additionally, users seeking a compact, bus-powered portable amplifier for mobile phone use will find this unit less appropriate due to its requirement for an external 24V DC power supply and desktop-oriented footprint.

Key specifications

  • High-resolution PCM playback up to 384 kHz/32 bit
  • DSD playback support for 2.8 and 5.6 MHz
  • Equipped with 12AU7 tube amplifier and ES9018Q2C DAC chipset
  • 3.5 mm and 6.35 mm headphone outputs
  • Supports headphone impedance from 16 to 600 Ohm
  • 3-band hardware equalizer for treble, mid, and bass adjustment
  • Inputs include Micro-USB, S/PDIF optical, RCA/phono, line-in, and aux in
  • Outputs include line-out, S/PDIF/pre out, and bass out
  • Compatible with Windows and Mac OS X operating systems
  • Durable metal housing in black color

To set up the InLine AmpUSB-EQ, connect the unit to your computer using the included USB cable and plug the external 24V power supply into a standard wall outlet. Install the provided drivers and software from the included medium to enable full ASIO support and optimal performance. Use the front panel input select button to switch between connected sources, adjust the volume using the analog rotary knob, and plug your headphones into either the 3.5 mm or 6.35 mm jack depending on your hardware.

What to consider before purchase

  • Verify that your computer operating system is compatible with the supported Windows or Mac OS X versions
  • Ensure you have adequate desk space for the unit, which measures 112 mm in width, 94 mm in depth, and 45 mm in height
  • Confirm that your headphones fall within the supported 16 to 600 Ohm impedance range
  • Check your existing audio sources to ensure they match the available optical, USB, or analog inputs

For optimal sound performance and longevity, place the unit in a well-ventilated area away from direct heat sources, allow the vacuum tube a brief warm-up period before critical listening sessions, and use high-quality cables for all audio connections.
