The attenuators need to go into the receiver slot at each end. I am indebted to @kennyb123 for his guidance and experiments, which he reported here on AS on the EtherREGEN threads. Please search for his posts. I appreciate the kind words, Rajiv. My experiments continued and I have actually moved on from the Startech FMCs. I’m now using the Planet Technology SFPs without attenuators as listed here. My upstream FMC is now the opticalModule and downstream it’s the ER. Clarity and focus improved with the Planet Tech SFPs - I think partly due to them not needing attenuators. The OM also offered a nice improvement over the Startech FMC. I can honestly say that I am done as far as trying different SFPs. The next step for me will be to get better power supplies for both the ER and OM. Rajiv it was really helpful that you provided observations on the use of different power supplies with the ER. I’ll probably go with the Farad for the ER. skatbelt, austinpop and Puma Cat 2 1 Digital: Sonore opticalModule > Uptone EtherRegen > Shunyata Sigma Ethernet > Antipodes K30 > Shunyata Omega USB > Gustard X26pro DAC < Mutec REF10 SE120 Amp & Speakers: Spectral DMA-150mk2 > Aerial 10T Foundation: Stillpoints Ultra, Shunyata Denali v1 and Typhon x1 power conditioners, Shunyata Delta v2 and QSA Lanedri Gamma Revelation and Infinity power cords, QSA Lanedri Gamma Revelation XLR interconnect, Shunyata Sigma Ethernet, MIT Matrix HD 60 speaker cables, GIK bass traps, ASC Isothermal tube traps, Stillpoints Aperture panels, Quadraspire SVT rack, PGGB 256 Link to comment

Moreover, this high-bandwidth noise from these CPUs is picked up by unshielded speaker cables, which acts an antennas for high-bandwidth noise and is fed backwards into the power amp, only to be re-amplified as noise. The best thing you can with respect to any music server is to locate it as far away from the audio rack as possible. Mine is 40 feet away from the audio rack, I run fiber from it to the network bridge. This is really good advice - advice that I should actually follow. In my case the two noise generators are my Innuos server and Hugo M-Scaler. My OPTO-DX provides me with the ability to place these I think up to 5m away from the rest of my gear using an optical connection. One of these days.

The DAVE has a cross-feed feature, as does my TT2. I do think that some Chord headphone users appreciate having this feature. I don't do headphone listening with my TT2 so I have no opinion on this feature.

I used these: https://www.amazon.com/gp/product/B0099S4MZI Nice thing about that choice is they acknowledge using Corning fiber. They don’t say which variant but this seems a good choice. I’m using this as well and after a brief search didn’t see any other option that would be obviously better for relatively short runs of single mode. For longer runs there is a ClearCurve fiber that has some advantages as far as installation. There’s also another type of Corning fiber that’s optimized for multimode called InfiniCore. The fiber that Sonore sells to use with their multimode SFPs uses this fiber. Excellent choice for their multimode SFPs, but probably not a good choice for single mode’s longer wavelengths.
