I've been following the advice of @melm, @dbb, & @sns with streaming improvements & it's been VERY beneficial.
- D-Link DGS105 switch (with ifi iPower X power supply 5v)
- AQ Pearl Ethernet cables
- Fiber Patch Cable (30')
- 2 Ethernet to Fiber converters (both with ifi iPower X power supplies 5v)
- Linear Power Supply to streamer (I went with Nuprime LPS-212)
The cost to improvement ratio has been a bargain.
