Not that I needed another piece of audio gear, seeing/hearing/reading about the Denafrips Ares, it seemed to check all the boxes for me. I bought one and was fortunate enough to have ordered an original Ares model and received an Ares II. Not that I'll likely now ever know what the DAC sounds like that initially attracted my interest, the Ares II is a spectacularly good-sounding, versatile, nice-looking, well-made DAC. I'm very pleased with the DAC and with Vinshine. All are exemplary. Thanks to Alvin at Vinshine and Denafrips. Thesycon USB driver for Windows. The Ares II uses/licenses a USB driver software from Thesycon. When I first set up the DAC, I simply plugged and played. All seemed to work just fine. Inquiring about the software available for the Ares II, Alvin at Vinshine said to install the Thesycon USB driver. I have and have been using the DAC with it. With JRiver MC25, after the Thesycon driver installation the MC25 configuration options went from something like "high res USB device" to choices identifying Denafrips specifically and a choice of ASIO and WASPI. My question is, why use the Thesycon driver? I'm running the latest builds of Windows 10. Is there a benefit to use the Thesycon driver with the Ares II? Better sonics (which I suppose the the ultimate objective/end point)? Better something? Does anyone know what is going on with the Thesycon technology? Thanks!
