CONCERO is a family of 352.8/384kS/S outstanding audio DACs. We have listened to customers and industry experts who asked us to deliver a sound signature similar to that of the INVICTA with fewer features and in a simplified format. CONCERO is that product. It is the Asynchronous USB Audio 2.0 and Jitter Reduction elements of the INVICTA driving the latest ESS Sabre DACs. CONCERO uses the 24bit ESS ES9023 Sabre DAC, CONCERO HD and CONCERO HP both use the 32bit ESS9018-2M Sabre DAC*. In addition, we have added an S/PDIF input for those configurations that do not use a USB data source. The CONCERO (except HP version) also allows USB input to S/PDIF output in a bridge mode. The HD and HP versions accept PCM and also DSD from USB Audio 2.0 (in 64x or 128x modes, ie DSD64 and DSD128). The HD version streams DoP data to the S/PDIF output when in DSD64 mode.


CONCERO is the upgradeable DSP engine of the INVICTA, including its proven Asynchronous USB Audio 2.0, Outstanding Jitter Reduction capability and the Proprietary Resonessence up-conversion filters delivering 176.4kS/s & 192kS/s from your 44.1kS/s & 48kS/s sources. CONCERO supports USB up to 384kS/s.


HP-Plugged-B-Smaller CONCERO HP is three things in one: first, it is the Resonessence upgradable FPGA DSP core with all the proven filters and algorithms of the CONCERO family; second, it uses the 32bit ES9018-2M Sabre DAC in both PCM and DSD modes to provide high quality audio; and finally it provides a state-of-the-art headphone driver capability.


Similarly to all the CONCERO family, the CONCERO HP enumerates on the PC as a USB Audio 2.0 device (by use of our freely provided Thesycon USB Audio 2.0 driver), and natively on the Mac. But in addition, CONCERO HP also enumerates as a Human Interface Device (HID) which allows its volume control to drive the volume level in the music player directly. (Learn more about the volume control)


When internal up-sampling is being used (taking your 44.1kS/s or 48kS/s to 176.4kS/s and 192kS/s) pressing the center of the volume control knob cycles through the Resonessence up-sampling filters for you to optimize your listening experience.


CONCERO HP is designed to be the only audio device you need to take your library of digital music in whatever format you choose, to your high quality headphones. Laptop, CONCERO HP and quality headphones together make an outstanding audiophile system.


Plug CONCERO into an active USB port and CONCERO enumerates as an audio output device. Now you can use CONCERO with your favorite music player on the MAC or PC, and experience a new level of audio clarity. CONCERO will optionally up-sample your digital 44.1kS/s and 48kS/s provided over the USB, into both an analog output from its internal ESS Sabre DAC’s into your existing audio pre-amplifier inputs or to your headphones. CONCERO (not the HP version) is also capable of generating a 24 bit ultra low jitter SPDIF stream output.


If you prefer to provide your own data at higher than 48kS/s, all CONCERO models will render it bit-perfect into the DAC (and SPDIF stream if not HP) while providing exceptional jitter removal.
Plug CONCERO into a power-only USB port (of the type used to charge cell phones or similar), and finding no active host, CONCERO will configure to accept SPDIF input. Once again offering to up-sample 44.1kS/s and 48kS/s into high quality 176.4kS/s or 192kS/s, or render it bit-perfect and jitter reduced into to the internal Sabre DAC for your pre-amplifier inputs or headphones.


CONCERO models respond to the Apple IR Remote for you to conveniently control the USB host track selection and play/pause, and on-the-fly select the ideal internal filter to suite your taste. No glitch or artifact is generated during filter switching, allowing you to audit the filters and choose the optimum. Pressing the volume control knob on the HP model also cycles through the filter selections.
