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.
