Just a PSA for anyone with stuttering issues when playing back over the network:
Gigabit ethernet is approximately 1000 times faster than necessary to transmit uncompressed CD quality audio. Actual need is less since it is the compressed file (flac/ape/mp3) that is transferred not the uncompressed signal.
Gigabit ethernet is 20 times faster than needed for bluray playback and about 10 times faster than needed for 4k bluray.
If someone is having stuttering issues, they are most likely due to server/NAS performance, or network congestion.
You should consider either:
1. Eliminating performance issues on your server or NAS
2. Implement QOS in your home router to ensure sufficient bandwidth is reserved for your a/v transfer needs when the network becomes congested.
As long as you are on a wired network, any such issues are correctable and you need not live with them. If you're using wifi, get used to the occasional stutter.
