I will try your suggestion and see which works best. Thanks! |

Uptone and the ER manual indicate that it's effective either way. The caveat is if you go in on the B side and put on the A side, don't connect anything to the other A ports, to keep it clean.

In the meantime, I ordered the SoTM sNH-10G switch, with the optional built in clock and the external master clock input. That will likely take a couple weeks to arrive. The Lumin X1 is supposed to arrive tomorrow. |

However....Emile Bok of Taiko has found that connecting "servers" on A-side and going out to the "destination device" (e.g. a Lumin, for example) via fiber, also on A-side, can, in some systems, sound better than going out via "B-side". And, in fact, that's what I've also found, as well, in an experiment I did just last week. Here's what I did: a) The Mac Mini Roon Core is in a "remote server room", next to my home network's Pace router; the Pace router has 4 plastic RJ45 jacks on it. Previously, I had the Mac Mini and EtherREGEN each connected one of these plastic RJ45 jacks with Shunyata Sigma Ethernet cables. The Sigma that came "out" of the Pace router when into B-side of ER and out via LC/LC optical fiber on A-side to the Lumin P1 in the main rack in the living room. b) Based on Emile's findings that A-side of ER can deliver really "clean" signal, last week I connected my Mac Mini's Sigma Ether to one of the RJ45 jacks on ER instead of to the Pace router, and...lo and behold, it sounded quite a bit better. In this configuration, I had the Pace router connecting to ER via...B-side. c) I then tried connecting the Mac Mini's Ether via B-side, but it didn't sound as good as when connected on A-side, and the Pace router connected via B-side. d) Given, that I then connected the Pace router's Ethernet cable to A-side as well, but that sounded the worst. So, now my set-up is: Pace Router -> Sigma Ether-> B-side of ER. Mac Mini-> Sigma Ether -> A side of ER. ER -> LC/LC fiber to the P1. My hypothesis as to why this sounds best is that the "moat" between A/B sides is preventing all the crap from the el-cheapo Pace router and it's chees-y plastic jacks from getting through to A-side on ER. And...connecting the Roon Core to a quality RJ45 jack with 12 isolation transformers/jack is better than...connecting via chees-y plastic jacks on a Pace router. Funny how that works...

Trials & Tribulations - scene #5
I had ordered: StarTech.com Cisco GLC-LH-SM Compatible SFP Module - 1000BASE-LX/LH - 1GE Gigabit Ethernet SFP - LC 20km - 1310nm - Cisco IE3400, IE3300, IE3200 (SFPGLCLHSMST) Finisar FTLF8519P3BNL 1000BASE-SX 2.125Gb/s 850nm LC Connector SFP Transceiver 10GBase-SR SFP+ Transceiver, 10G 850nm MMF, up to 300 Meters, Compatible with Cisco SFP-10G-SR, Meraki MA-SFP-10GB-SR, Ubiquiti UniFi UF-MM-10G, Fortinet, Mikrotik, Netgear and More, Pack of 2 1.25G SFP Transceiver 1000Base-LX, 1310nm SMF, up to 10 km, for Cisco GLC-LH-SMD, Meraki MA-SFP-1GB-LX10, Ubiquiti UniFi, Fortinet, Mikrotik, D-Link, Netgear, TP-Link TL-SM311LS and More, Pack of 2 8 Meter Singlemode Duplex Fiber Optic Cable (9/125) - LC to LC - Yellow 8 Meter Multimode Duplex Fiber Optic Cable (62.5/125) - LC to LC - Orange FLYPROFiber LC to LC Fiber Patch Cable OM3 8M, Length Options: 0.2m-200m, 10GB Multimode Duplex LC-LC 50/125um Fiber Optic Cable Cord LSZH-8Meter(26ft) Zyxel Multi-Gig 12-Port Unmanaged Switch with 2-Port 2.5G and 2-Port 10G SFP+ Desktop/Wallmount, 5-Years Warranty [XGS1010-12] Various lengths of BJC Certified Cat 6A Patch Cable (Blue Jeans) And auditioned all of them. While I was waiting for the SFPs recommended by Stephen: https://planetechusa.com/product/mgb...x-module-20km/ and this, by far, made a huge difference in the sq. Then, my amp crapped out. I am returning all except the Planet Technology USA mentioned by Stephen. Yesterday I received https://sotm-usa.com/products/snh-10g But I still haven't connected it, since I am having amplifier-subwoofer issues. I am down for the count until I get a replacement amp while mine gets checked out. |

I'll just add that I found out about the Planet Tech SFPs because they were recommended by Emile Bok of Taiko Audio. He did extensive testing and found that these were the best.
