The Hermes is a Digital To Digital Converter. It took 3 years for Denafrips to perfect its development. It leveraged the technologies found in their award-winning DAC, namely, their proprietary FPGA DSP processing, FIFO buffer & reclocking, industry leading USB audio interface solution via STM32F466 Advanced AMR based MCU. I am feeding the Hermes with the USB output from my OpticalRendu. The Hermes I2S output feeds the I2S via HDMI cable to the Denafrips DAC. I am also using the OCXO clock output of the DAC to synchronise the Hermes. The Hermes/T-Plus combo are achieving the best sound I ever had in my system.
The Denafrips Terminator plus is a reference-grade DAC with proprietary R2R + DSD Architecture. The Terminator Plus is easy to use and can play both PCM and DSD files. It is seriously well made with a very sturdy/heavy construction. It offers native I²S transmission using several types of cabling. It offer superb sound at a reasonable price.
