If you're familiar with Foobar, for DVD-A's you need the DVD-Audio decoder plug-in, for SACD's, you need the SACD decoder plug-in. Once you have those set up in Foobar, you should be able to play the ISOs directly on a pc using Foobar. For streaming, you then need to set up streaming profiles using the UPnP plug-in. I've spend some time fiddling with settings and I'm still learning what some of the option are. I use a separate profile for SACD because it seems finicky. Here is my SACD streaming profile for streaming to my Oppo:
Use profile when: User-Agent contain OPPO (Note: this is dependent on what device you are streaming to. OPPO is what works streaming to my Oppo, Playstation 3 works for my PS3)
sample-rate range: 88200 to 88200
Max bit depth: 24
Transcode to MP3: Never with Except box empty and lossless and internet connection unchecked
Decode to PCM: never to lpcm with Except box empty
Audio Processing: no DSP's active
Also, in Basic Settings, untick the Always use the default streaming profile for all devices
For the SACD plugin, make sure the ASIO Driver Mode is set to PCM and PCM Samplerate is set to 88200. I'm also currently using the DSD2PCM Mode of Direct (Double-Precision, 30kHz LF) but others also work, some better than others when streaming. With a couple of modes, I was getting stuttering or pauses. Streaming SACD ISOs is fairly CPU intensive, but the plugin has come a long way and is much better than it used to be.
For DVD-A's, the major difference is I change the sample-rate range to 44100 to 192000 because I have DVD-A's that have all types of sample rates. For some reason if I use this setting for SACD ISO's, Foobar wants to resample everything to 192000.
For the Playstation, I've created a different streaming profile and change the Transcode to MP3 setting to Always, change the Max bit depth to 16, and a few other changes. When the Foobar media server is selected by the device (in my case Oppo or PS3), the appropriate streaming profile is automatically selected.
Hope this helps.
