Digital-to-Analog Audio Converter

The ESTONE unit converts optical Toslink, USB flash-drive or Bluetooth 5.0 sources into stereo analogue signals on RCA L/R and a 3.5 mm jack. It supports PCM and LPCM at sampling rates of 32, 44.1, 48, 96 and 192 kHz with 24-bit depth. A built-in headphone amplifier delivers 125 mW per channel into 32 Ω and suits headphones from 16 to 300 Ω. The package includes a USB power cable, IR remote and manual.

Home listeners adding wireless

This converter suits anyone who wants to stream from a phone via Bluetooth 5.0, play lossless files from a USB stick or connect a TV Toslink output to a legacy stereo amplifier or powered speakers. The headphone output also serves late-night listening. Buyers needing multichannel surround decoding, HDMI connectivity or balanced XLR outputs will not find those features here.

192 kHz maximum PCM sampling rate

The highest supported optical and coaxial sampling rate is 192 kHz at 24-bit, which determines whether high-resolution PCM sources play at native resolution. If your source material exceeds this rate or uses formats other than PCM and LPCM, the device will not decode it.

Questions about this item

What headphone impedance range does the 3.5 mm output support?

The headphone amplifier is rated for 16 to 300 ohms, so most consumer headphones will work directly without an extra amp.

Will the optical input accept the PCM stream from my older DVD player?

Yes, the optical input handles PCM and LPCM at 32, 44.1, 48, 96 and 192 kHz sampling rates.

How can I confirm the DAC is decoding a 192 kHz signal after I connect it?

Play a 192 kHz test file from a USB flash drive or via Bluetooth 5.0 and verify sound comes through the RCA or 3.5 mm outputs.
