  4. Fully-balanced differential DAC/amplifier with >1,040mW output.
  5. Ultra-fast USB interface with 16 logic cores and up to 2000MIPS 512KB SRAM.
  6. Audiophile-grade components designed to reproduce music without any distortion or colouration.
  7. Native DSD/PCM Burr-Brown® 4-channel DAC chipset.
  8. Perfectly natural sound pleasing even the most demanding audio connoisseurs with the built-in MQA file decoding.
  9. Extremely low THD: <0.0015 % and ultra-high SNR: >120 dB.
  10. Digital inputs: USB3.0 B (USB2.0 compatible)/S-PDIF (coaxial/optical)/Bluetooth 5.0TM.
  11. The special custom aviation-grade aluminium base matched to the NEO iDSD.

OLED display

The OLED display shows the audio format, sampling rate, volume and input mode.Note: OLED screen is on left side when iDSD is lying flat.

Multi-function knob

This knob controls:

  • Variable/Fixed mode (use with power button)
  • Analogue volume control (turn)
  • Mute (short press)
  • Brightness (long press)I) Variable/Fixed mode selectionThis mode will determine whether or not the NEO iDSD analogue volume control is used.The NEO iDSD must first be switched off to allow mode selection when powering on.Hold down the knob first, and then press the power button to enter the Variable/Fixed mode selection. Turn the knob to cycle between the two modes. Release to accept.Tip: If no mode is selected the NEO iDSD will automatically select the previously used mode.ii) Analogue volume controlThe analogue volume control in the NEO iDSD is superior to any digital volume control. When set to‘Variable’, it can be used to control the headphone or the pre-amplifier volume. If the mode is set to‘Fixed’, the volume control is bypassed.Note: The NEO iDSD uses ONLY a pure analogue volume control.iii) MutePress the rotary knob to mute. To unmute, press it again or turn the rotary knob.iv) BrightnessPress and hold the knob (3 seconds) to enter brightness selection. Rotate the knob to cycle through the three brightness modes and press to accept.Note: With the ‘high’ and ‘low’ brightness modes, the OLED will remain on. With the brightness mode ‘off ‘, if no operation is performed, the OLED will go to sleep after three seconds.

Input channel selector/Bluetooth pairing

This button cycles through 4 inputs:

Note: Please select the input channel according to your audio source input mode. For example, when using USB input, you need to switch the input channel to “USB”.

The NEO iDSD receives Bluetooth signals via aptX, aptX HD, aptX Adaptive, aptX LL, LDAC, LHDC/HWA, AAC and SBC.

Bluetooth pairingFrom selecting the Bluetooth input, the NEO iDSD’s OLED will flash searching for the previously paired device. If it cannot find the stored device, it will automatically enter pairing mode and flash.To enter pairing mode, press and hold the button (for three seconds) until the Bluetooth icon flashes. To pair, find the iFi Hi-Res Audio Bluetooth device from the nearby devices list on your phone.The NEO iDSD can store up to 8 paired Bluetooth devices.

Power On/Off

Press the power switch to power on/off the NEO iDSD.

Balanced 4.4mm analogue output

Connect balanced 4.4mm headphones.Tip: As the NEO iDSD is a balanced design, we recommend the 4.4mm balanced output.

Single-ended 6.3mm analogue output

Connect single-ended 6.3mm headphones. With single-ended 3.5mm headphones, connect using a 3.5mm to 6.3mm adapter.

XLR balanced analogue output

Balanced analogue signal output to an amplifier.

RCA unbalanced analogue output

Single-ended signal output to an amplifier.

Coaxial Digital input

Connect an S/PDIF source such as Apple TV, Google Chromecast, PS4, a high-end CD transport, etc.

Optical Digital input

Connect an S/PDIF source such as Apple TV, Google Chromecast, PS4, Xbox, a high-end CD transport, etc.

USB audio input

This is a USB 3.0 B input (USB2.0 compatible). For a superior connection to a computer, use the enclosed USB3.0 cable. It connects the NEO iDSD to the computer audio source.

DC 5V power input

Please connect the NEO iDSD to the enclosed power supply, the super-silent iPower. The NEO iDSD must ONLY be powered by 5 volts.Tip: For best performance upgrade iPower to an ultra-low noise iPower X 5V power supply.


Please attach the enclosed antenna for maximum reception quality.
