I did try out QNAP, Thecus and Synology and ended up with Synology as the most reliable solution for me. besides Audio streaming (which doesn't need to much throuput) I use for editing and streaming 4k and 4k+ video.
Today's configuration is an Synology DS1813+ in the following configuration:
3 1 GB Ethernet ports as span ports bundled for the switch connection to my MacPro Video Editing Machine via an HP Switch
1 1 GB port directly connected to my Jriver Audio PC
4 GB Ram extension
6 4 TB WD Raid
2 Samsung SSD 512 GB Evo 840 pro (as cache)
