Have you actually ever tested this? Takes all of 5 mins to setup Samba and a NAS on the Pi.
I've even streamed over 1 GB video files on the network.... to tablets, smartphones, and even Windows PC running PotPlayer and madVR.
Never had any stuttering, dropped frames, or jitter.
The only folks I know who keep parroting this shared BUS issue with the Pi are the folks at CA. You really cannot go by them. That's a crazy lot and filled with sellers, sponsors, etc. For them it has to be DSD only, upsampling player like HQP, expensive streamers like Auralic or Aurender, LPS only for power, and the only music worth listening to is western classical, etc. Don't start drinking that Kool-Aid my friend and take everything shared at CA with a pinch of salt.
Even folks using Kodi on the Pi will tell you it never stutters or hangs... the shared BUS is not an issue.
