When it comes to streaming high-res audio files, having a reliable media server software can be crucial for achieving optimal playback quality. For those looking to stream music from their PC, Mac, or NAS drive to a DLNA renderer like the Marantz 7702mkII preamp-processor, JRiver Media Center Asset UPnP is an excellent option.

As Trey M. pointed out in his question, Windows Media Player (WMP) may not be the best choice for streaming lossless files such as FLAC and ALAC. While WMP can work with uncompressed WAV format files or those compressed using common lossy schemes like MP3, it lacks native support for high-res file types.

In fact, WMP requires additional transcoding to play FLAC files, and even then, it may not be able to handle files with higher resolutions such as 24bit/192kHz. This is why JRiver Media Center Asset UPnP or Twonky Server are great alternatives to consider.

JRiver Media Center Asset UPnP offers a range of features that make it an attractive option for those seeking high-quality playback. Its ability to stream audio, video, and image files over a home network makes it easy to access your media library from any room in the house.

With JRiver Media Center Asset UPnP, you can rest assured that your high-res audio downloads will be played back at their best quality. Whether you're listening to FLAC or ALAC files, this software ensures that your music is streamed seamlessly and without compromising on sound quality.

In conclusion, when it comes to streaming high-res audio files from your computer to a DLNA renderer like the Marantz 7702mkII preamp-processor, JRiver Media Center Asset UPnP is an excellent choice. Its ability to handle lossless file types and provide optimal playback quality make it an ideal solution for audiophiles seeking the best possible listening experience.
