DAC • Preamp • Headphone Amplifier

DAVE is an acronym for "Digital to Analogue Veritas in Extremis"

This gave opportunities to further improve performance:

Improved time domain (transient timing accuracy)

Improved noise-shaper performance

DAVE has much more advanced analogue electronics


The primary purpose of a DAC is to reproduce the un-sampled continuous analogue waveform from sampled digital data

Conventional DACs do a poor job of reproducing the original continuous analogue signal, with timing errors on transients

Increasing tap-length of FIR filters gives better time domain accuracy in terms of the timing of transients

The ear/brain is extremely sensitive to very small timing errors

Timing accuracy upsets the perception of the start and stopping of notes

It also degrades the ability to perceive instrument timbre and power

It degrades soundstage precision

DAVE has a 164,000-tap WTA filter.

The noise-shaper takes the high-resolution 2048 FS data and converts it to 5 bits

20-element Pulse Array DAC.

Ultra-low-noise sub-milli-ohm power planes for Pulse Array element flip-flops.


Maximum output voltage 6V RMS – the reference voltage dBA, measured using APx 555

THD and noise at 5V RMS 1kHz -124 dBA A wt

THD and noise at 2.5V RMS 1kHz - 127 dBA A wt (-124 dBA into 33 ohms)

THD 1kHz 2.5V RMS 0.000015%

Dynamic Range at -60 dBFS 1kHz -127 dBA A wt

No measurable noise floor modulation, no anharmonic distortion

Analogue distortion characteristic – no distortion for small signals.
