Originating in Weiss Engineering’s product line for professional mastering studios, the HELIOS is truly a zero-compromise DAC. For those seeking the same representation of their music as mastering engineers hear when fine-tuning the audio in the studio, the HELIOS is the unit to get.

The HELIOS comes with digital inputs in numerous formats and has both balanced and unbalanced analog outputs. All standard sampling frequencies up to 384 kHz plus DSD x64 and x128 are supported. 

Furthermore, the unit functions as a preamp, headphone amp, and a streamer (UPnP/ROON).

The HELIOS also seamlessly integrates with the JPLAY iOS app – you can enjoy your favorite tracks from Qobuz, Tidal, and your local collection, all in one unified library.

To achieve its exceptional performance specifications, the HELIOS uses an eight-channel 32-bit D/A converter chip, with four paralleled conversion channels per audio channel. All analog processing is done with our own discrete operational amplifier modules, the Weiss OP2-BP — arguably the best audio operational amplifier currently available.

It also uses an internal high-precision/low jitter clock generator for ultra-stable clocking of the D/A converter section.

The built-in digital audio processing is based on the same trailblazing algorithms that are used in Weiss Engineering’s professional audio tools. 

So with the HELIOS you can adjust the audio using the same professional-grade algorithms that were used to mix and master the original recordings.

The HELIOS comes with an IR remote control which can be used to select the active input and output, the DSP audio processing presets, and switch power on and off.

Furthermore, it is possible to control and configure the HELIOS via a web browser, which adds detailed control of the DSP processing and preset management.
