I did some experimenting with my Opus, Melody, DacMagic and high resolution files today, and here are some highlights.
I was able to stream all of the Gimell test FLAC files (up to 24/96) across my network from the Opus to the Melody, and play them using the digital out on the Melody into the DacMagic. I was also able to stream mp3 and m4a files from the Opus to the Melody without any issues.
The MV2020 is a different matter. It does not support FLAC, so I was unable to try that. I was able to stream mp3s and wav files from the MV2020 to the Melody, but in both cases the artwork is missing. I was unable to stream m4a files or wma files even though the MV2020 supposedly supports those formats.
Now, I don't know if the issues with the MV2020 are the MV2020 or the Melody. I get the impression the UPNP/DMA standard is not really locked down, so incompatibilities between "compatible" devices is not uncommon. The HP website only shows a handful of Digital Media Adapter devices that are compatible with the MV2020.http://h10025.www1.hp.com/ewfrf/wc/d...roduct=3193058
So, if someone is thinking of purchasing a Melody with the intention of using it to stream files from a UPNP/DMA server, I would give Olive a call first and see if they have any insight into which UPNP/DMA devices work and don't work with the Melody.
FYI - I had Twonky installed on the MV2020 at one point, but deinstalled it when I got the Opus. I ran out of time today, so trying the MV2020 with Twonky will have to wait. I'll let you know when I have a chance to re-install Twonky on the MV2020.
