It is, but It still doesn’t seem to support DSD. It also didn’t update the samba protocol to smb2, so the file shares still aren’t showing up on my network. I’m not entirely sure what it did, but if you believe the readme.txt file, it “improves HDMI audio” and tweaked the front LCD panel, which I don’t use.
Audio plays fine, tidal and my cd rips sound as good as before, but without the file share access and DSD compatibility it’s hard to recommend this over an Antipodes DX, for instance. Granted, the ADX quite a bit more expensive (especially with the lifetime roon subscription) but it has a complete feature set.
Keeping my fingers crossed that NAD can get the M50.2 over the finish line. It’s not quite a finished product yet.
