  1. Something for a chuckle. Was browsing over at Audio Science Rewiew and came across this definitive statement by its founder and chief Audio Precision worshiper Amir: https://www.audiosciencereview.com/forum/index.php?threads/topping-p50-power-supply-for-my-rme-dac.11005/#post-309737 Someone is asking about replacing the SMPS wall-wart that came with their RME ADI-2 DAC and Amir proclaims simply “No power supply has made any difference that is remotely audible.” I’m guessing not too many of you here would agree. So you’d best stop fussing over power supplies and DC cables, etc.—because you are all delusional!
  2. Hi Jean-Michel: Glad to hear that you are so happy with your new combination of EtherREGEN plus eRED-DOCK. The company engineered SA has always been an interesting one to me as they started out with people from Anagram Technologies, then formed abcPCB, and also CH-Precision. We studied some of the abcPCB modules earlier (NMR and USB), and I have been watching with interest the new eRED series. Funny thing is, their web site still shows the eRED-DOCK as not being available until March of this year. So you managed to get one early? As with most all Ethernet endpoints, the audio streaming protocols it works with can be a limiting factor when it comes to choice of player software. Clearly Roon RAAT and HQ Player NAA are out for eRED endpoints. Can Roon see it at all as a UPnP/DLNA renderer? If you built the box with jacks in your photos, you might consider using a piece of 75-Ohm coaxial cable for the internal link from the board to the jack (though I see you use an RCA jack instead of a BNC so for that it might not make much difference). Cheers! --Alex C.
  3. Amazing to see all this discussion of power supplies without a single mention of one of nearly the most consequential factor, output impedance. Computers are a very “bursty” load, and given adequate current and even just average noise performance, the supply with the lower broadband output impeadance will always win.
  4. So would the bulls... It has a “ring” to it...
  5. Me too! Some of her CDs are not easy to find...
  6. Sure, that cable will work fine. It is multimode with LC connectors, matching the SFP transceivers we reference. Here is a simple and informative page to read to get up to speed on the basics of common fiber optic cables: https://www.fibercables.com/pages/picking-out-fiber-optic-cable
  7. I have a 6-page draft of it which I will be editing this weekend--into a condensed version to be used as a Q&A requested for a forthcoming formal review of the EtherREGEN. For the measurement portion, John is still writing some code to capture and process the raw data from his Wavecrest timing analyzer as the software it comes with produces only averages of the measurements he wants (he can explain in more accurate detail if he wishes). It is rather complicated. Truth is, we are both exceedingly busy at present and given that no clones of ourselves are showing up each morning to handle our most pressing tasks, a number of non-essential chores often get pushed out. So we thank you for your patience.
  8. "Obtained" as in I bought one for you and had Amazon send it you via next day Prime? I guess the "robustness quality attributes" criticisms you eloquently communicated really apply more to the variation in SFP transceivers that Sonore is supplying--as those are the only ones yet reported to be finicky in the EtherREGEN's SFP cage.
  9. Hi: Sorry to see that your early 2016 LPS-1 has been damaged. REG8 is a Linear Technology LT8612 synchronous buck regulator with 28 pads in a QFN package. There must have been a VERY large spike (18V+) from whatever supply you were using to charge the unit, as that's what typically can blow a hole in that regulator. Not only will field replacement of that part be very difficult, but there are likely other parts on the board which are also damaged (even if you do not see visible signs). I believe you are already working with Yuriy, who is a Sonore dealer there? He sent me that photo of your unit last week and we made a generous offer to him for an upgrade--of your out-of-warranty unit--to the new generation UltraCap LPS-1.2. Such will be a much better deal for you than shipping your LPS-1 here and paying for repair. Thanks, --Alex C.
  10. FYI: Further production update and pics posted here...
  11. Wednesday, January 15th, 2020: The last of the January-promised EtherREGEN orders shipped to overseas buyers today! The look on the face of the clerk at our local FedEx drop-off location when we brought in 75 packages (the other 25 went via the post office) was priceless. Another 225 EtherREGEN circuit boards arrived today (plus 275 more will be here in a few weeks). But aluminum cases for February shipments won't ship from our supplier until February 14th (hopefully sooner). We'll program, test, and attach the heatsinks to the boards in advance, so once the cases arrive it won't take long to assemble, package, and prepare shipments. So realistically we are looking at the week of February 24th. Certainly not later, and possibly earlier. As of tonight, 91 of these next 225 EtherREGENs are pre-sold (for shipment late February). Plus nearly 100 are already reserved by our dealers. Wow, that's 191 committed out of 225. I was really hoping that we would not sell-out February before the end of January, but now that seems likely. So if you are thinking about ordering an EtherREGEN directly from us, you'd best hurry as there appear to be only a little more than 30 spots open for the February batch. Thanks everyone! -------------------- Some of what shipped today. And a big batch of JS-2 units ready for Q.C./test/burn-in this weekend. No resting around here!
  12. A couple of things in the instance of using the 'A'-side SFP cage as "output" to your renderer (opticalRendu): 1) It is best to not use the other Gigabit 'A'-side RJ45 ports for other devices--so that you keep the complete isolation/clocking pure to your endpoint; 2) For the other upstream devices you mention, it will be best to keep those on another switch--ahead of the EtherREGEN--and then just feed one copper connection from that switch to the EtherREGEN's 'B'-port. So for your use, you will just use the EtherREGEN as a highly isolated, dual-clock-domain FMC: copper in, fiber out. Bandwidth will not at all be an issue. People are using EtherREGEN (with its 100Mbps 'B'-port) with DSD512 and 4K video.
  13. This is the wrong thread for such updates, but it's my fault for posting the January status update above. Still I'll answer briefly: Another 225 EtherREGEN circuit boards arrive the end of this week (and another 275 after that in a few weeks). But aluminum cases for February shipments won't ship from our supplier until February 14th (hopefully sooner). We'll program, test, and attach the heatsinks to the boards in advance, so once the cases arrive it won't take long to assemble, package, and prepare shipments. So realistically I think we are looking at the week of February 24th. Certainly not later, and possibly earlier.
