Can minim server apply different setting by DLNA render?

It is worth trying. The full description of how to do this is in this section. For what you have described, the stream.transcode property should be set to dsf:-/wav24;96. This sends two streams: the first (-) is not transcoded and the second (wav24;96) is transcoded to PCM WAV at 24/96. The order is significant because if things are working correctly the control point should use the first stream that is playable on the selected renderer.
