  1. Paul is not alone anymore (think he has one employee) and SR4T are batch built each month so the wait is not that long right now.
  2. Why not get a Paul Hynes SR4T-12 then you can switch between 7,9,12V and see what is best.
  3. If you have an "endpoint" with fiber input like a Sonore opticalrendu or a Lumin X1 for example.
  4. If I am not wrong the Denafrips RJ45 connections are for i2S signals so you cant use that connection going from the Melco to Denafrips as that is not a Network DAC that has to be USB. Only place to put the etherREGEN is before the Melco on the network.
  5. If you use Roon I would connect a hard drive directly to NUC as the files always have to go via Roon core no matter where the file is loacated on the network. So IF it would work to put the harddrive in sMS-200 the file would anyway go to Roon core and then back to sMS-200 and that makes not much sense to me.
  6. You will not violate the isolation when you power the etherREGEN and a modem on the A-side with a JS-2. If you where to power the etherREGEN and a component on the B-side then you would defeat the purpose of the isolation as JS-2 have a shared -0V for the two outputs.
  7. Yes, you dont have any leakage to block between A-ports as you only have fiberoptics on the A-side.
  8. All Paul Hynes PSU are floating designs so if you want to ground the eR you need to do it via the groundscrew when powered with a floating PSU. The grounding affects how the filtering between the A-side ports works. This is from the manual. Please keep in mind that all of the above regarding grounding concerns only the blocking of leakage from one RJ45 jack on the ‘A’ side to another RJ45 jack also on the 'A' side. Regardless of grounding, zero AC leakage from upstream Ethernet devices ever gets past the full active digital isolation and reclocking ADIM™—to the EtherREGEN’s 'B'-side port.
  9. Older HD Plex only had three windings on the transformer so two outputs shared the -0V (12 and 19V). The latest 200W model have four seperate windings on the transformer so all outputs have seperated -0V. I use the latest HD Plex 200W and run the 12V rail to my etherREGEN. As I only use one RJ45 on the A-side (fiber input from router) to my server I have tried both with and without grounded -0V but cant say that I hear any difference.
  10. I would say it is never a absolutely necessary to use the ground screw but it can be usefull if you use two copper connections on the A-side so you make a path to drain away leakage that way. I run fiber to my eR and only use one RJ45 port on the A-side and in this case the ground is not needed but it does not hurt to use it (I have tried both cant say that it made any difference). I have a floating PSU that powers my eR). If you use a powersupply that have the -0V connected to ground (like the supplyed SMPS) then the eR is automaticly grounded as the -0V inside of the eR is connected to the same groundplane as the groundscrew so then you already have the eR grounded via the PSU. As @Superdad wrote all of this is covered in the User Guide. https://cdn.shopify.com/s/files/1/0660/6121/files/EtherREGEN_User_Guide.pdf?99 Use of the EtherREGEN’s Ground terminal screw:We have measured high-source-impedance leakage on Ethernet cables coming from various other common network gear and computers.Leakage is common-mode AC current traveling over DC connections. It is pernicious stuff—passing easily along both analog and digital connections in our audio systems—and it is desirable to shunt it away. We address leakage in the design of the EtherREGEN in several ways, including our use of RJ45magnetics having 12 tiny transformer coresper port. And their center-tapsare wired to ground and to theEthernet switch chip through capacitors to maximally block port-to-port leakage. This works best if the EtherREGEN is grounded—either through the power supply or via the ground screw.The DC output 0-volt/-VE (‘ground’/shell)of the UpTone-branded AC>DC power supply included with the EtherREGEN is common to AC mains ground. When our supply is used to power the EtherREGEN it is NOT necessary to use the Ground screw.[Do not assume that 3rd party linear power supplies are like this—some are and some are not. Some multi-rail supplies have separate diode bridges and transformer secondaries and thus each output ground is "floated.” This is easy to test with a continuity/multimeter (be sure power is disconnected.)]If you power the EtherREGEN with a "floating" supply—one whose 0-volt/-VE (‘ground’/shell)is not common to AC mains ground—then ideally the Ground screw of the EtherREGEN should be used. You can do so by running an insulated wire safely to some AC mains ground or to the chassis of a known-grounded component in your audio system. [By the way, our UltraCap LPS-1.2 is a completely "floated" and isolated supply, so if using it with EtherREGEN the ground screw should be used.]Please keep in mind that all of the above regarding grounding concerns only the blocking of leakage from one RJ45 jack on the ‘A’ side to another RJ45 jack also on the 'A' side. Regardless of grounding, zero AC leakage from upstream Ethernet devices ever gets past the full active digital isolation and reclocking ADIM™—to the EtherREGEN’s 'B'-side port.
  11. The ground screw on the eR is not for safety it is a functional earthing. This is a type of earthing forms a functional part of an electrical installation. Interference current can be discharged from the filters on the RJ45 A-side for example. I would not use anything that has a high resistans to ground the eR to a ground in a outlet.
  12. You connect the ground screw on the eR to protective earth in the outlet that you have pluged the iFi supply in. The simplest way is to use a grounded plug that you just connect a wire to ground in and connect that wire to the ground screw on the eR and plug it in besides the ifi.
  13. Nucleus is based on a regular Intel NUC and they support 12-19V on the DC barrel so no problem driving a Nucleus on 12V. I measured my NUC7i5BNH it has M.2 SSD for ROCK OS and second SSD for music. This is with regular 44.1/16 no DSP 19Vdc average 0.57A (10.83W) and peak 1.5A 15Vdc average 0.69A (10.35W) and peak 2.1A 12Vdc average 0.81A (9.72W) and peak 2.8A Average is during play to Roon endpoint. Peak was during start up (might be higher than this as my instrument might not be fast enough. I have not measured amp usage during a scan for example but if all cores are being used during a library scan I suppose we can see constant use high as peak is in my test.
  14. My eR is in a complete different room from my system in a cabinet fixed to a conrete wall so not much vibration to deal with. I have still considered to use some type of rubber damping between brakets and cabinet.
  15. I bought them from a company in Germany called Reichelt. All my network equipment and Roon ROCK machine is in a cabinet that is fan cooled.
