Fully balanced design built by discrete analog stages without any OPA and coupling caps in the signal channels.
Non- feedback ACSS analog output stage.
Total of 7-groups dedicated power circuits and more than 38,000UF caps are used to purify the power supply.
Four-channel digitally controlled relay-based volume control to avoid channel imbalance and improve sound quality.
80 steps volume level control in both high gain mode and low gain mode. 160-step volume control ensures smooth control of the volume level.
3 digital inputs: Coaxial (BNC & RCA) / Optical / USB * BNC and RCA coaxial input- only one can be connected at a time.
DAC output: XLR *2 / RCA *2 / ACSS (User can set to either variable or fixed output level )
Headphone output: 4 pin XLR / 1/4" (6.3MM) SE
USB Audio Class 2 High-speed Input from Windows / MAC / Linux
Supports High / full speed Asynchronous Transfer Mode up to 384K / 32Bit.
Supports Resolutions of 16 / 24 / 32 Bit with sampling rates of 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz ( USB )
Supports up to 24 Bit/192KHz ( SPDIF )
Used single ended (1/4" headphone jack or RCA output), is the NFB-10.33 fully utilized?
NFB-10.33 is a real balanced DAC . It has balanced outputs (ACSS, XLR and balanced headphone output) and single-ended, RCA outputs . There are 4 ACSS amplifiers in the NFB-10.33 for balanced outputs and balanced inputs. Even when a single-ended output is used, the dual WM8741 DA chips will perform fully thanks to the fully balanced design.
What's improved in the NFB-10.33 ?
1, Upgraded to 80 steps volume control (was 48 steps) .
2, Adjusted for a more analog sound.
3, The chassis is upgraded with all aluminum construction.
4, Upgrade to BNC coaxial input (with RCA coaxial connected in parallel)
5, Upgrade to OCC wires.
6, More outputs ports available in DAC mode and Preamp mode, and they can be connected simultaneously. (XLR*2 , RCA *2, ACSS *1)
