More info

Its ultra-modern DAC allows you to manage 32bit 384kHz sources directly via Amanero (Asynchronous) USB interface and 32bit 192kHz via S / PDIF inputs.

This version incorporates the same new features as the NFB-1DAC namely:

  1. a better Saber implementation proposing a shorter signal path
  2. the possibility of selecting the hardware filters
  3. a DSD auto-detection (with switching noise-free switching).
  4. The disengagement of the preamplifier function (by a button on the back) allows a pure DAC use.

The 100% discrete and symmetrical design of this amplifier is backed by a high-power isolated power supply and a selection of high-end components (R-core transformers, DALE resistors, WIMA capacitors and 2 ultra low Jitter TCXO clocks.

Included Options:

  • Remote Control Aluminum
  • USB Interface Amanero
  • TCXO Clock (DAC)
