The new ASIO driver for all Gustard DACs is now available (version 5.50). They are working on the website, and they are now posting firmware updates there.
I just emailed someone through the Gustard website. The first response said it wasn't possible to update the firmware and the second email said there are no firmware updates. This is odd at best......
This is a magnificent DAC. Well done! I have the F.1a firmware. Any reason to upgrade (Windows 11 / USB)? I have no issues so far. Where is the official site to download firmware upgrades when they are final? Thank you!
