For your computer digital sources, You can do much better. Much lower jitter.
Options:
1) Empirical Audio Interchange DLNA renderer with HDMI I2S output - you can use Jriver or Audirvana+ as players
2) Empirical Audio Off-Ramp 6 XMOS USB converter (galvanically isolated) with HDMI I2S output - no driver needed for Mac or Linux
These should match or beat your transport.
