RE: AMR DP-777SE not USB Audio 2.0 compatible?

"AMR develops their input firmware and drivers for OSX/Win"

According to this page: http://www.amr-audio.co.uk/html/dp777_driver-download.html
They do supply a driver for Win. Small wonder as Win doesn't support UAC2
They don't supply a driver for OSX.
OSX is UAC2 compliant.
Likewise the iFi products: http://ifi-audio.com/downloads/

It looks like they do use UAC2.
Not to be mistaken for a good implementation.
A rule of the dump is that if a USB DAC works with OSX without installing a driver, it is UAC2 compliant.
Hence it is reasonable to expect it to work with recent Linux as well.

That is what I thought also, but... - 91derlust 02:46:13 12/05/16 (2)
that relates to the DP-777, not the DP-777 SE. It is my understanding that the SE uses a different USB input. The firmware is likely different, but I take your point about the driver download (no OSX) and the likelihood of compliance.

However, AMR has clearly stated in recent correspondence that they don't support Linux - why not if the Linux driver is UAC2 compliant? Could they be UAC2 non-compliant but still work with OSX?

Let's see what AMR comes to me with.

Cheers,

  Interesting. It wouldn't be smart of them to not support Linux with the DP-777 SE. If this is true, then they may not support several dozen popular audiophile music servers and network streamers out there that are based on Linux.

    A lot of servers are Linux-based!
    
    Unless there is something I'm missing, if the DP-777SE was UAC2 compliant it should work with UAC2 compliant Linux servers.
    
    Thankfully the DP-777SE has a nice SPDIF in and the Antipodes can do SPDIF out... though I'd rather be using USB.
    
    I want to get off system merry-go-round, but might take a look at a different DAC if I feel like leaking a few more $.
