I have a few questions regarding my Roon setup and if there is anything I should change. First off this is what the chain looks like:
Router (without internet access) -> Ethernet Switch -> Late 2009 iMac (Wifi for internet) + Bryston BDP-1 (both connected to the switch).
Nothing else connected to either the router or switch. Bryston BDP-1 in Roon Ready with nothing else attached to it and all other services disabled.
Router: Linksys E3000 (I’ve disabled both wireless bands)
Switch: D-Link DGS-1005G (http://ca.dlink.com/products/connect/5-port-gigabit-desktop-switch/)
Ethernet cables: Regular Cat 5e that I had from before.
Other audio gear that’s in the room: Torus IS 15, Dangerous Music Source powered by Teradak 12V13A, Amphion Amp 100 + One15 + Amphion cabling, Grimm TPR for AES and analog cables, and 2 x Jitterbugs attached to iMac for now. I don’t know if any of these will have any negative interactions with the networking gear or vice versa.
I want to make it clear that I am not experiencing any obvious networking problems that I can tell. Only looking for potential improvements in sound. Zero dropouts with 16 and 24 bit WAVs. No latency issues.
1) Should I keep this plastic gigabit switch or swap it out for a managed one or one with metal casing? Anything to be gained from optimizing the switch settings in this particular case? I did notice that the sound differs when I had the iMac and BDP-1 connected directly to the router vs. the switch.
2) Changing power supply of the switch? Anyone have experiences with changing the PS of the switches with a LPS or a switching like iFi iPower? This one in particular uses a 5V 1A adapter. Any recommendations or suggestions? What about the Teradak U9 or DC30 or the ifi iPower? This is the listed specs for the switch:
Power On (Standby):
DC input: 0.4 watts
AC input: 1.1 watts
DC input: 2.37 watts
AC input: 3.9 watts
3) All this gear is in the vicinity of each other. So, the ethernet cables only need to be a few feet long (~6 feet max). Given the gear mentioned and close proximity, any benefit to swap out the cat 5e with 6, 6a, or 7? Shielded or unshielded versions? I did read about the shielded versions possibly messing with the galvanic isolation if connected on both sides. Any thoughts for my context? Blue Jeans makes those bonded ethernet cables. Anything to be gained there? Looking for reasonable priced items here.
Please let me know if there are other things that I should consider that haven’t covered here. Many thanks!
