I know we are discouraged from ragging on other forums, but this was simply too silly to ignore. Spied from a post on a forum
@amirm helped create and is now banned from (WBF).
Here's someone who went down the 'Ethernet/Wifi carries/generates noise' hole way too deep. Fyi, 'LHY' is a manufacturer (a subsidiary of 'Jay's Audio'), and 'FMC' stands for fiber-optic media converter:
"Here are the items that I use on each of my Xfinity Cable Modem, Firewalla Gold Pro Hardware Firewall / Router, and LHY FMC:
1) LHY Linear Power Supply (for each the Cable Modem and Router)
2) Swiss Digital Fuse Box with Extreme Piggy Tail & Graphene Sluggo (for the Linear Power Supplies of Modem and Router, and for FMC)
3) Vanguard White Label Silver DC Cable (for the two Linear Power Supplies for Modem and Router)
4) Lessloss Prime Power Cord (A/C outlet to each of the two Linear Power Supplies and to the FMC)
5) Synergistic Research Atmosphere SX Reference Ethernet Cables (Modem to Router, and Router to FMC)
6) Synergistic Research MiG 3.0 Footers (Three under each of the Modem, Router, and FMC)
The LHY FMC connects to LHY SW-6 switch via 30 meters of Optospan LCELite Ultra Low Loss Fiber Optic cable and Optospan 'PSFP-11DT31K002' SFP's. LHY SW-6 connects to DAC / Streamer via Synergistic Research Atmosphere SX Reference Ethernet Cable.
Thus, I do not use WiFi in streaming music. I do use one ethernet port from the Firewalla Gold Pro Hardware Firewall / Router to connect to a Firewalla AP7 which feeds other AP7's for mesh network to support WiFi needs of non-audio devices.
I'm getting ready to set up the audio system devices on a separate VLAN in my firewall / router to isolate it from other devices. Will report back if it makes an audible difference."
This is a recent post, and he has not posted a follow-up report about this. But he did make a post about how every SMPS
in your house needs to be replaced with a linear power supply....
Notice he uses ~3 of each of the items listed, on various devices. I don't have the patience to look up prices, but my estimate is that this guy spent over $10K to improve his $200 modem/router....
Someone named Holmz at WBF, not sure if it is our
@Holmz, has asked in various 'digital noise' threads at WBF, "What noise?" They just refer him to "the obvious noise...."
So true audiophiles, with Golden Ears,
can hear 'digital noise,' but
can't hear record-surface noise, tube noise or tape hiss.
Isn't it scary how sanity in this hobby depends entirely on which forums or websites are used for information....
