question about my config...

[aspaceintime]

I was able to get minimstreamer working on my setup after many tests. I have an instance on MinimServer on my Synology NAS DS212j. I use a Marantz SR 6010 and an Oppo 203 as my players. I have several radio playlists that finally work; Here's my stream transcode ; aac:L16/wav24/- , *:L16/wav24/-
On all the radio streams I have, it plays as PCM.

My question - Is this the most effective way to play these streams? I looked at the info button on my Oppo while a radio stream was play and the file size was enormous. If I have a blank stream transcode, nothing plays. Not sure what would be the best sounding setup with my gear.
Thanks
