  1. According to Allo this occasional blinking is not a cause for concern. Apparently pi demands cause the voltage to drop below 5v momentarily which trigger a blink.
  2. Allo Digione Signature red light blinks every five minutes or so. Sounds great but I worry the dirty side power isn’t supplying sufficient current. I have tried the iFi 5v 3A power supply and a 5.25v 2.5A generic power supply on the dirty side and both make the pi board blink every once in a while. Is this a problem if the sound is good? Configuration: Rpi 3b+, piCorePlayer 5.0 (audio kernel), Small Green Computer 7v LPS to clean side, Monoprice premium USB A to C cable on dirty side, Edimax WiFi dongle AC1200 (dual band on 2.4). Substituted a 5.5x2.1 to USB C adapter for the 2.1 to 2.5 to USB C stacking adapters supplied with the transport. Could the usb dongle be drawing enough current for an occasional red light wink? I appreciate all thoughts and thanks.
  3. Raspberry Pi3, HifiBerry Digi+, PicorePlayer software, Wyred 4 Sound uDAC, Stereovox HDXV coax, Audioengine 2 speakers. Streaming Tidal through the RPI sounds way better than a modest system of this sort has any right to. Huge fun.
  4. piCorePlayer will stream Tidal nicely through a Raspberry Pi. For a remote app try iPeng, or the Logitech Squeezebox app for free.
  5. I'm a longtime Vortexbox user and continue to be amazed at its ability to do so many things well and sound great at an affordable price. Back to the Sonic Transporter: Michael Lavorgna of Audio Stream seemed to like it very much. Intel NUC & sonicTransporter: A Tale Of Two Mini Computers Running Roon Core | AudioStream
  6. USB DACs and streaming have their challenges, what with electrical noise and bus communication conflicts. So what is the argument in favor of USB rather than coax or optical connections? Manufacturers I respect (Ayre and Sonore for example) make products that only work with USB. I own examples of each. Is the argument that laptop computers emit lower RFI but don't generally have coax capability? If this argument prevails, why do manufacturers struggle with USB to spdif converters? Not trying to start a flame war, I just wonder what the reasoning is behind the differing philosophies. Thanks.
  7. Wireworld Starlight 7. A year ago I borrowed three cables from the Cable Company -- the Wireworld, a Shunyata Venom, and an Analysis Plus Purple. My desktop system consists of a Wadia PowerDAC mini, Schiit Wyrd, and Kimber 4TC speaker cables to Audioengine P4 speakers. To my ears, the Wireworld cable projected a much larger soundstage and had greater dynamics compared to the other two and compared to the Kimber Cu Bus that I had there in the first place. For the modest cost ($100/m), the Wireworld made a nice improvement. The speakers now seem to be the weak link.

  10. So here's the update after six weeks: The Multibit upgrade did the mighty Bifrost a world of good. From cold out of the box, the Bimby had greater ease, better frequency extension, and a more 3D soundstage than the Ultra Analog. With time, those qualities became more pronounced. The word that comes first to mind is organic -- musical and relaxed in a vacuum tube sort of way. Midrange frequencies are lush, round and full, while high frequencies (like cymbal crashes) are extended but unforced in a very analogue vinyl sort of way. The Moon 100D still throws a larger soundstage while the Bifrost casts instruments in distinct places in a more compact space. Maybe the best endorsement of the Bifrost Multibit is that it is easy to listen to for extended periods without fatigue. There are competitors in the $600 range but this one is special and my experience with the company has been first rate. Take a listen to a well broken in example and decide for yourself.
  11. I bought the Schiit Wyred and continued to be surprised to hear how much it does for the laptop/Wadia PowerDAC Mini.
  12. First off, the Moon 100D for all its compact cuteness is a wonderful DAC. It casts a soundstage well beyond speaker borders and excels at pacing and rhythm. It fit the bill for my modest bedroom rig and if it weren't for curiosity I would not have changed. First impressions after a weekend of constant streaming through the Bifrost are good. The multibit upgrade improved the soundstage dimension considerably (a real strength of the Moon). Instruments take on a dimension of their own and midbass and bass lines are prominent if just a tiny bit flabby. The sound in a macro sense is more organic and round. Dynamics are extended and quite clear without a trace of harshness or glare. While I haven't had extended listening sessions yet, I'm guessing they will be a fatigue free experience. In all, an impressive first experience. Looking forward to continued improvement as the Bifrost settles in and irons out its wrinkles.
  13. [Crickets] OK, Schiit was prompt about returning my Bifrost with the multibit upgrade and mega ultra super combo plate burrito. I'll fire it up when I get home and see how it compares to the Moon 100D and my memory of the Bifrost Uber Analog ala carte taquito plate. I can't help but like this company. They put the DAC in a plastic bag and shipped it a factory box with the old parts and new rubber feet. Oh, and they gave me the test sheet that identifies the tech who did the upgrade and confirmed the DAC is functioning properly. All this costs them time and money and they insist on doing things right. Bravo.
  14. I have listened to uncritically to a Moon 100D DAC for a couple of years now, linked to a W4S mINT played through a Squeezebox Touch and Vortexbox server. Speakers are Silverline Minuet Supreme Plus, cables are Transparent MM2 RCA, Black Cat Veloce S/PDIF, and Transparent MWP speaker cables. Overall, a decent bedroom system. I bought a used Schiit Bifrost Uber USB 2 DAC and found to my surprise I like the Moon better. The Moon seems to throw a larger soundstage in comparison and has better frequency extension. I played the Bifrost for six weeks and it has improved somewhat and reproduces midrange well but, otherwise, I prefer the Moon, especially in the areas of dynamics and pace. I'm beginning to think there is something wrong with the Schiit (which could explain why it was given up for adoption). It's off to Valencia for the multibit upgrade so we'll see where that takes things. I have great regard for Schiit and the reviews lead me to think something is amiss. Has you mileage varied? Does it take longer than that to burn in the Bifrost (who knows how many hours it has on it)? Do I have a system incompatibility? Thanks, looking forward to your views.
  15. My experience has been positive also. This is a company that is trying hard to build a following.
