I own an Oppo-93 connected via HDMI to a Marantz AV7005. I use it to play SACD's, but for CD playback I use my home computer. I ripped my CD collection to FLAC files and stored them on the home computer. I have a wired connection from the PC to the Marantz. Marantz offers DLNA to allow playback of the computer files. For DLNA to work server software is required on the PC. I initially chose Twonky. It worked well. I used it for several months until I read about jRiver Media Center. jRiver offers a 30 day free trial so I installed it on the PC, following jRiver's setup guidlines. The improvement in sound quality over the Oppo-93 playing the CD to the Marantz and Twonky streaming via DLNA to the Marantz was pretty astonishing. My entire CD library became much more listenable, so much so that I have spent the last several weeks listening to it again. The improvement in sound qualities that i perceive are: higher resolution sound (a lot more detail), wider sound stage, and a deeper, almost three dimensional, sound stage.
If your Anthem does not have DLNA, jRiver recommends connecting an HTPC running jRiver to a receiver/prepro using HDMI. They suggest the quality of sound will be better than DLNA.
Hope this helps in your decision.
