Resonessence Labs Invicta












Canadian Resonessence Labs's Mark Mallinson was former Operations Director for chip maker ESS Technology. Their design engineers and owners are DAC experts and were key in the design of the ESS Audio DAC, including the 9018 SABRE that is used in some of the world best (including our reference, the Weiss DAC202).


Their first product, Invicta, a stereo DAC, combination of careful audio, electrical and mechanical engineering. The Invicta supports many major audio inputs and outputs. Two headphone outputs along with an SD card reader. The back panel reveals a high speed asynchronous USB audio, Toslink, BNC and AES/EBU input. All common sample rates are supported, and are displayed on the front panel. The analog outputs boasting both RCA and XLR.  The Invicta uses a large OLED screen where audio source, volume, song selection, are displayed (for SD Card playback). 130dB signal to noise ratio (typical) and 0.0002% total harmonic distortion (typical) specs are up there with the best.  Solid engineering couples with deep digital know-how and good ergonomics should ensure that this will be a great unit.
