The DAC-S is an all-solid-state DAC with eight 32 bit AKM4399 per channel in mono mode, M2Tech 24/192 hiFace USB interface built in, discrete output stage, no negative feedback, no capacitors in signal path, and galvanic isolation of digital and analog stage.
Features:
- Professional grade digital input receiver
- Asynchronous Hiface USB interface by M2Tech built-in. 192kHz/24bit capability
- Asynchronous upsampling working steady at 195kHz/32bit
- Very low jitter Master Clock oscillator
- Second generation, top-line 32bit DACs by AKM of Japan; 8 per channel for much reduced noise floor, working in Mono mode for up to 10dB better channel separation
- No negative feedback, linear phase, transformer-coupled Analog output stage featuring Lundahl Amorphous Core audio transformers and high-current output buffers
- No capacitors on the signal path
- No Op Amps
- Galvanic isolation between Digital and Analog stages, eliminating digital noise ground interference in the Analog output stage
- Attenuator control with 0.5dB step. No preamp required
- LCD display with blue back light, dimming steps and OFF mode
- Digital and bar-graph attenuator level displays for easier user interface
- Low latency and Normal digital filter selection
