Title: Ethernet cable
Post by: watchdog on February 07, 2017, 09:47:59 PM
Anyone here with experiences on tweaking the Ethernet cable chain ? JB has in another thread posted about using optic fibre.

For myself, even changing the Ethernet cable from the NAS to router makes a noticeable difference. I've tried LAN filters (like the one from SOtM) and the difference is very obvious too.

i have tried several different LAN cables, mostly factory-terminated patch cord - Belden Cat6+, SANWA Cat 7, China-made Cat7 and Prismian Cat 6+. Each has its own merits. However, LAN cable inherently inject electrical noise from the switch to the DAC clock and chip. Optical isolation is quite an essential measure to filter off the noise. Some DACs such as North Star Design has in-built optical isolation chip such as Texas Instrument ISO7xxx series.

I have moved onto Aurender N100H music server which plays from a SSD cache, mainly because of Aurender's superb app and the reduced number of equipments in the system.

Some of the forum members here have extensive experience with optical network links, and the power supplies for the receiver / transmitter boxes. I'll let them chime in here on this.
