You are correct. I thought you meant as a dap. We are working on the DSD128 for USB.
Thanks for
henryc and his
idea to use a compatible driver, I'm even more happy owner of DX80!
Those tests with iBasso USB DAC driver I was performing at work, under Windows 7. But at home I still use Windows XP. Unfortunately, iBasso does not provide drivers for Windows XP. They failed to start even with manual install.
But the driver by iFi Audio runs under Windows XP just fine! Moreover, it supports native DSD128 playback via DX80!
In addition to what
henryc said, you need to copy iFiHDUSBAudioapi.dll and iFiHDUSBAudioasio.dll somewhere (e.g. into WINDOWS directory), and manually register them:
regsvr32 iFiHDUSBAudioapi.dll
regsvr32 iFiHDUSBAudioasio.dll
By the way, iBasso D14 DAC uses the same USB receiver hardware, the same driver source, and does support Windows XP! They are based on generic binaries version 2.24, iFi uses version 2.23 (I mean, version of the
generic drivers! iFi display version is 2.26), drivers for DX80 are based on 2.26.
So, Paul, I'd ask you to try supporting Windows XP in the next driver release, and add DSD128 support. While I see no a reason to change drivers right now, it would be a pleasure to install native drivers from you
