The Helios DAC brings the highest levels of pro performance to consumer audio, exceeding even the standards of the highly regarded DAC501/502. It is an extraordinarily versatile unit, featuring a number of Weiss-developed DSP algorithms.
Digital processing is performed by the 8-channel ES9038PRO chip, utilizing 4 DAC channels in parallel per audio channel. This practice results in an unmatched S/N ratio of -128 dB, and provides superb channel separation and noise rejection.
A powerful non-switching power supply is used, and all voltages have their own regulators which are separated between left and right channels. The result is an analog output free of noise and channel crosstalk. The power supply utilizes two toroidal transformers.
There are five digital inputs: AES/EBU or S/PDIF via XLR, Toslink, or RCA; RJ45 Ethernet; and USB type B. Outputs are line/headphone balanced XLR and line/headphone unbalanced RCA. All inputs accept all professional or consumer signals and Helios is Roon Ready.
Unique to Weiss Engineering DSP algorithms are inspired from both the pro-audio and home audio domains and include a Room Equalizer, to suppress room modes, a Creative Equalizer, with low, mid, and high boost/cut, De-essing, which removes overly-bright sibilance, Constant volume, which adjusts volume level across all tracks being played, Vinyl Emulation, which mimics the sonic characteristics of LPs, Crosstalk Cancellation (XTC), which allows playback of binaural dummy-head recordings through loudspeakers, Loudness Control and a Crossfeed algorithm which emulates a loudspeaker listening experience while using headphones.
Analog output stages utilize Weiss’ own OP2-BP discrete op-amps, providing superb sound quality that is vastly superior to that provided by monolithic op-amps, the company says.
Control of the unit is by a front panel rotary encoder knob, the provided full-function remote control, or by a web interface.
The Helios housing consists of a stainless steel chassis with a thick aluminum outer frame.
