Pre-order: expected ship date to be announced
Eversolo's R2R DAC, preamplifier and headphone amplifier: an in-house discrete resistor ladder with NOS, OS and BEST modes, fully balanced from conversion to output, with a 10 MHz OCXO clock and a linear power supply.
The Eversolo DAC-R8 is an R2R ladder DAC, preamplifier and headphone amplifier. Conversion runs through Eversolo's own discrete resistor network instead of an off-the-shelf DAC chip, and the chassis is proportioned to match the Eversolo T8 streaming transport, so the two stack as a pair.
How does it convert?
Origin R2R, Eversolo's in-house resistor ladder, is FPGA-driven, 5+20-bit and fully differential. Three conversion modes are a touch away on the front screen: NOS (non-oversampling), OS (oversampling) and BEST. The signal stays fully balanced from conversion to the analog outputs.
How does it measure?
From the balanced XLR outputs: THD+N of 0.000316% (−110 dB) at 1 kHz, a 130 dB signal-to-noise ratio, 130 dB dynamic range and −142 dB channel separation.
What powers and clocks it?
A custom O-Core linear power supply, and a 10 MHz OCXO (oven-controlled crystal oscillator) with a PLL for internal timing. A 10/25 MHz external clock input accepts a master clock such as the Eversolo C10.
How is the volume set?
A fully balanced, stepped R2R volume control attenuates in the analog domain, so low listening levels keep their detail and dynamics.
What can I connect?
Digital inputs: USB-B and I2S over HDMI (up to DSD512 and PCM 768 kHz / 32-bit), an electrically isolated AES/EBU input, coaxial and optical (up to PCM 192 kHz / 32-bit and DSD64 DoP), HDMI ARC from a TV, and Bluetooth 5.4. Analog inputs on XLR and RCA. Outputs: balanced XLR and RCA preamplifier outputs, plus a 6.35 mm headphone output with three gain levels for headphones from 16 to 300 ohms.
Display and build
A 5.2-inch IPS touchscreen with VU meters, a rotary volume knob, a remote control and the Eversolo app. The chassis is CNC-machined from a single block of aluminum alloy and measures 315 × 230 × 75 mm with feet; it weighs 4 kg.
