  1. Thanks for clarifying this for me, Alex. I will place an order. Early post-holiday splurge for me.
  2. Yes, it is an optical rendu and I understand that I would have to go from B to A for the reason you mentioned. I just wanted some reassurance that I would get performance similar to what others get from going in the opposite direction.
  3. Thanks, Alex. If I can round up the scratch, I will place an order and see how this works out.
  4. Thanks, Puma. I can see that I wasn’t clear about the information I solicit. If I understand your configuration properly, you are connecting to your endpoint using copper on the B side RJ45. In contrast, I want to use the B side copper port upstream of the SFP. In other words, I want the signal to go from the B side to the A, connecting my rendu end point to the SFP. I think Jud tried that, if I understood his first post correctly, but preferred going from A to B.
  5. It sounds as though Jud tried but abandoned using the optical port as the downstream one for sound quality reasons. Is anyone else connecting a device through an SFP module and, if so, how are you feeling about the ER in that application? I ask because I have an optical rendu now connected to the network with a Sonore optical module that I would switch to another system if the ER is an upgrade of the magnitude this thread suggests it is.
  6. Sorry. When you referred to "you guys, " I thought that included me.
  7. I only play files stored on a NAS over the network, mostly using MPD/DLNA but sometimes LMS. They can be anything from low bitrate mp3 (as low as 128 mbps) to DSD. Recently, I have been focusing on high res PCM and DSD files, though. I also enjoy using the system as a jukebox, bouncing from album to album or shuffling a playlist rather than listening to a single album all the way through. My system rarely conks out while playing files. Once a listening session starts, it usually lasts until I shut off the music. The system most often conks out after being powered but idle for awhile, in which case saving the MPD/DLNA or LMS app again in “settings” sometimes gets it back on track. (When I can’t get music to play audibly after the system has been idle, even though the control software says it is playing, I sometimes, but not nearly always, note that the DAC displays an incorrect sampling rate.). Most often, though, it happens after I have run the update routine in Apps (whether or not I reboot after finding no changes were made), after a power failure or shut-off (we are remodeling here), or if I am changing something in my system that makes it prudent to shut off the Rendu. In those cases, I run my routine set out above. Usually, I can get a restart after no more than two or three times through my checklist. These are the routine issues. As you may recall from correspondence after I bought the SE, I had some DAC issues (handshaking, XMOS 24-44/88 bug) that manifested similarly. Those seem to have been resolved by a DAC firmware update.
  8. This hasn't ever solved my problem, although I sometimes have had good luck swapping in a $3 USB will get things going. I then can swap my regular cable back in. (And, yes, the cable manufacturer has assured me that my regular cable is fully USB 2.0 compliant, so my issues aren't caused by using a wonky audiophile non-spec cable.)
  9. Jesus' and your posts remind me that, when I get really frustrated by having to go through this cycle, I both restart the router and unplug both the Rendu and DAC. The two devices don't have to be unplugged for more than a few moments before being plugged back in. Those extra steps sometimes take care of the playback issues.
  10. Please indulge me the recycling of what I posted in this thread a few months ago, as I have found that it is a useful routine when I experience issues like yours after a firmware update or residential power failure or on other occasions when my Rendu/DAC combination decides to go silent. **** (1). Turn off power to the Rendu, the DAC, and the FMC/OM (if applicable). (2). Repower in this order, one unit at a time: (a): FMC/OM; (b). DAC; and (c). Rendu. (3). When the DAC repowers, allow it to complete its full power-on routine. (4). When the Rendu starts to repower, make sure that default 44.1khz sample rate displays on your DAC, if you have a DAC that shows the rate. (5). Allow the Rendu to complete its power-on cycle and then find its control interface on your phone/tablet/computer browser. (6). Go to the Rendu interface's Apps tab. Check DAC diagnostics to be sure that the first and third windows on the screen confirm that the startup handshake completed. If not, repeat steps (2) through (5) until the handshake completes. (7). Go to the Rendu interface's Settings tab. Select the Rendu app that you use to control your music playback. Restart your controller software app by clicking on "save." Wait until the green status bar appears and confirms the software's restart is complete. (8). If your server software can be restarted, do that. (I use JRiver, located on my computer, so it's easy to restart it from my phone using remote access software.) After the server software restart completes, make sure the Rendu shows as a client, if your server software can show you that. (9). Restart your controller software app on your phone or tablet or your computer browser, whichever you use to play music through your Rendu. Make sure that both the server software and Rendu client are accessible from that your control app or browser. If not, try redoing steps (7) through (9). (10). Choose your music and hit "play." Usually, you will hear something, but sometimes nothing will start to play or music will appear to play but be inaudible. In that case, try redoing steps (2) through (9). (11). When all this fails, start again at step (1). Eventually, it works, as you have noted, unless you have network issues that I can't address here. I don't want to make this sound worse than it is. It takes under five minutes to run through and, soon enough, you get the steps memorized. Streaming, at least in my experience, always is fraught with more peril than just putting a CD into a player, choosing the right input, and pressing "play" on the player. The sound quality and jukebox capabilities of a streaming system make the effort to restart things worth the candle.
  11. I just use the power switch. Am I going to mess up something if I keep doing that?
  12. Jesus, what is the server software on Rendu #1? I assume you need to set up the Rendu as a server rather than a player.
  13. Kinda confused here. Are you referring to an Uptone LPS 1.2 or are you referring to a different linear power supply?
  14. Thank you, Kumakuma. I was not able to get my own image to post from my telephone.
  15. I am on a quick trip to Tokyo and stopped in at a bookstore to browse magazines. I found this cover depicting the ultraRendu and the UltraDigital on a Japanese magazine. There also is a review in the magazine's editorial content. I don't read a word of Japanese, so couldn't translate anything on the cover and in the review, but thought the cover cool. I am sure that the Sonore folks are aware of the coverage, but I doubt many of the rest of us do. [Edit: I am unable to get the attached jpg to display. If I cannot fix this during my edit window, I will try again in a new comment.]
