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.


CONCERO HD connects the Resonessence upgradable FPGA based DSP engine to the new 32bit ESS ES9018-2M Sabre DAC for high performance, high sample-rate PCM up to DXD rates (352.8kS/s) from the USB Audio 2.0 port. In addition, it also contains the Resonessence 4x up-sampling filters that will accept 44.1kS/s and 48kS/s data streams from USB or S/PDIF and convert them to 176.4kS/s and 192kS/s respectively.


CONCERO HD activates the ES9018-2M’s internal DSD processing engine to support Direct Stream Digital (DSD64 and DSD128) from the USB Audio 2.0 port using DoP standard version 1.1. CONCERO HD can operate as a USB to S/PDIF bridge in all modes except the DSD128 mode (that more would result in an S/PDIF stream data rate that exceeds the S/PDIF specification. DSD64 however does work, DoP data packets are send out on the S/PDIF in that mode).


CONCERO HD is designed from the ground up to deliver on the promise of Direct Stream Digital in addition to high sample rate PCM. It brings the latest ESS Sabre DAC chips and the latest standards in audio processing to your existing power amplifier and loudspeaker configurations.


*The CONCERO HD and CONCERO HP do indeed use the 32bit ESS9018-2M Sabre DAC but the data you send to our DACs is at most a 24bit word. What then is the reason to mention that the DAC is 32 bits? It is important, and it sounds better when the DAC is 32 bits, because of the signal processing the DAC must do can end up loosing information (ie making a very low level of noise) if the internal bus width cannot accommodate a dynamic range higher than the dynamic range of the input data word.
