Got my hands on a copy of SAM Broadcaster 2015.1 this morning despite Spacial trying to obfuscate the download links.
The changes list reads like this:
v2015.1 (1 June 2015)
* M4A support added.
* Check SAM Broadcaster edition and warn if overwriting a different edition
* Warn/disable when there is no support for WMA

Going through Shoutcast and tuning into a few random radio stations.
Some of them were quite good and sounded brilliant. Some of them however did not.
Digging a bit deeper and looking on their shoutcast DNAS server pages the reason for the poor audio quality on some of the stations was immediately clear.
