  1. I very much agree with that recommendation. I would like to add that you need to have a clear view of your 'strategy' in terms of DAC's input. There is no point IMO to try an S-P/DIF renderer if your DAC's S-P/DIF input does not process timing signals properly, or if it is not supposed to be the best input of the DAC. You could try an USB renderer and be very happy with that too. So 2 possible routes to the DAC: - S-P/DIF (or AES/EBU) ie synchronous protocols with your M2Tech interface or a Mutec MC-3+ USB... - USB ie asynchronous through an Allo USBridge renderer or Sonore µ-rendu or SOtM sMS-200... Finally, what was possibly difficult for you might have been the addition of DigiOne + Mutec or M2Tech. You can also mix the routes and go USB for the renderer and then S-P/DIF for the interface. You would then get a lighter reclocking effect, which is more conform to your habits/expectations.
  2. Obviously, everyone needs to check whether his/her own DAC benefits from the S-P/DIF clock improvement. This can be done theoretically, asking the DAC's manufacturer, or empirically, trying a reclocker and evaluating for oneself whether the effect is positive of not. In the case of my DAC, which is integrated into an amplifier (Devialet), the addition of a Mutec MC-3+ USB in the chain has been reported as positive by many contributors.
  3. Thanks for this precision and renewed congrats for the tests/report.
  4. Thank you. Can I ask what was the 'Energizer' used to power the LPS-1 ?
  5. Mine is working A-Ok with a tension of 6.0V, in connexion with a Ref-10 as the maximum advised by Mutec is 6.2V.
  6. A few hypothesis to take with a heavy grain of salt, as I do not pretend to have competences in the electrical engineering field: Could it be that: a leakage current is finding its way between the two boxes (MC-3+ USB and Ref-10) in the absence of the Habst grounding cable through the common 'ground', which causes the timing signal (spread between the 'hot' and the 'ground') to be much less readable on the MC-3+ end ? in the case of installations where the grounding has been particularly well done or when the MC-3+ USB have been transformed with a LPSU, this leakage current is not flowing there ? in which case a simple trick à la @JohnSwenson like this one () could help solve the problem without resorting to expensive cables ? Again, to take with reservations
  7. A short update here. When I wrote my enthusiastic thread about this DigiOne, I just had spent some days listening to it on a nice system (darTZeel LHC-208 + Voxativ Zeth), which is my secondary system. And the Digione was doing very well compared to the sMS-200 I have on this system. When I returned to my main (Devialet D1000 + B&W 802D3) system early this week, I installed a new DigiOne and started listening to it. I left it some time to break in. The results on this much more detailed system are quite different from my secondary system. On this one, the transparency and detailed restitution of high frequencies with the DigiOne is significantly lower than with my sMS-200 Ultra. On an album like this one (https://www.channelclassics.com/catalogue/23906-Quartets-kv370-kv421-Sonata-kv377/), the difference is very audible. So the hierarchy between the different devices is well kept as HB had stated in his report. Nothing to add. Case closed
  8. Hi Paul, I asked the forum admin to move the related posts to the new thread. Best, Pierre
  9. You probably need to burn your SOtM gear and enjoy it for a while before making the test... But, depending on the kind of music you are listening to, you might be missing, at some point, a kind of 'full body' which was given by the µ-rendu in the lower and medium range. This is true on certain performances of clarinette, cello, double bass , or some electric guitar / bass solos... Some people are sorting this out by adding an IsoRegen to the chain, but this is one additional PSU, and as Romaz once described, this needs to be upgraded by SOtM to have the full flavour. Another option is to try the DIgiOne, which offers a much fuller body to the music. As I already wrote, it enhances the effects of the MC-3+ USB, a little bit like if you had two of them, for a much cheaper price. The transients of some piano tones or the execution of the 3rd mouvement of the 8th symphony of Shostakovich is very different with this combination. The very high frequencies might seem a little less transparent at the very beginning. But you need to burn the small computer for sometime (some say 200 hours) before you can judge if you are missing the "ethereal" colour of the music rendered by the sMS-200 Ultra. Depending on your budget, at 200 USD, this is not such an expensive trial. You can use one of your 75 Ohm BNC cables to connect it and the sPS-500 to cleanly power it at 5V. A no brainer for me, once you will have exhausted the pleasure and the enjoyment of the gears you just received and that I would not want to spoil... Apologies for the wrong timing
  10. Hi Mourip, Assuming that you are ordering your DigiOne with the DietPi software, which is what I recommend, the system will arrive with everything installed. The interface of the DIgiOne is simple, and is based on a web browser. So you do not have to be skilled in Linux to use it. There is only one operation to make in Linux when you receive your box, and this is to select the DigiOne output board for rendering. This requires opening a terminal on your computer, type 2 simple instructions, and select the DigiOne board in the menu. That's about it. I am prepared to make a short tutorial about this and send it via PM if this is of interest to you. I do not want to spoil this thread with such details. A short point of architecture though: I am keen to keep the processes on the renderer very light. In order to achieve this, I am running Roon in server mode on another computer, which is a NAS, and located in the basement of my home. Therefore, the workload of the renderer (sMS-200 or DigiOne) is very minimal, it is not heating nor producing a lot of EM interferences. I mention this as this might be of importance for you as you did not precise what kind of player you are using. On the MC-3+ USB side, you just have to select the BNC input, as you will have plugged the DigiOne via a BNC cable on this input, instead of the USB one.
  11. I will not play on words. The only thing I would disagree with in the report of Hans Beekhuyzen I pointed to is the fact that he organises an implicit hierarchy based on devices' prices, saying that only the sMS-200 Ultra is worth sitting in his number one system, whereas the DigiOne is not worth it... For someone who, like most of Mutec MC-3+ USB users (not to mention the Ref-10 users among which I am fortunate to belong), has a DAC with a good S-P/DIF or AES/EBU input, and is sensitive to the benefits of reclocking (better analog presentation of music, deeper and more assertive bass, better general and micro-dynamics, aso), the DigiOne, connected to a Mutec MC-3+ USB, probably is an option to consider. And even on a system which costs more than 20'000 EUR, if adequately powered (will not reopen the debate here), its benefits could be audible. Just my 2c. I will mention the nice listening report of Confused on the MC-3+ USB and Ref-10 here: https://devialetchat.com/showthread.php?tid=4941&pid=72529#pid72529 As he has already posted in another thread, he might not want to cross-post. So I am doing this for him. Congrats @Confused
  12. Well, seems we have a disagreement, which is something I can live with. I am using a Paul Hynes LPSU. Please note that my main goal with this contribution was not to discuss powering of the DigiOne as such, a discussion which would be welcome in the dedicated thread for this player (https://www.computeraudiophile.com/forums/topic/37205-allo-digione/), but not so much here. I wanted to outline the nice complementarity between the DigiOne and the Mutec MC-3+ USB. IMO, the DigiOne is offering an additional value to the 'standard' network player, and this is the clocking component. When aiming at using a Mutec MC-3+ USB, which goal is to provide a nice and clean S-P/DIF or AES/EBU music stream, using a DigiOne might appear more adequate than a standard network player. If you have a Mutec MC-3+ USB, you might share your thoughts about this complementarity and this would certainly be useful to the readers of this thread
  13. Yes I have the stock wall wart sold with the bundle. And this PSU does not not allow to get the best results from the player. I am not the only one to have this view. You should check the review of the DigiOne: https://www.youtube.com/watch?v=8Iey5yKd-p4. Hans Beekhuyzen is sharing this view too.
  14. Hi Everyone, I recently made the acquisition of a small player, an Allo DigiOne (https://www.allo.com/sparky/digione-player.html), which I found interesting in connection with my existing reclocker Mutec MC-3+ USB and my Mutec Ref-10. What is relatively unique with this player is the capability it has to produce a stream of music in the form of S-P/DIF in the first place, instead of producing a more common USB music stream. S-P/DIF is a synchronous protocols, which embeds, in the stream, the musical information together with the timing reference of the music. It is therefore to be opposed to asynchronous protocols like USB, which do not include any timing reference, the musical data being buffered at the DAC prior to being processed with the DAC's clock as a timing reference. These synchronous protocols (S-P/DIF here) have opened the door to some interesting processing techniques, called 'reclocking', during which the music stream is plugged onto a improved timing reference provided by a more stable clock ie a reclocker. Mutec MC-3+ and MC-3+ USB are such devices. In addition to this, a new generation of very stable clocks has emerged, the first of them the Mutec Ref-10, which goal is to further improve the stability of the timing signal used for reclocking. The purpose of this thread is to discuss the interaction and complementarity of these two items (S-P/DIF player) and reclocker (Mutec MC-3+ USB). Here is an explanation of the data conversion process of the DigiOne: https://community.roonlabs.com/t/allo-digione-board/18564/128 In practice, connected to the Mutec MC-3+ USB with a 75 Ohm BNC cable, this small and inexpensive player makes a very good combination. A precaution though: to obtain the best results, you should upgrade the stock wall wart SPSU by a better one, possibly a LPSU if you can afford. This will largely improve the openness in the high frequencies and extend the assertiveness in the bass. Also, if you elect to use the DietPi software, you can choose to play with the priorities of the Roon RAAT Server in Linux, and get very unique results. The relatively inexpensiveness of the device makes the trial reasonable. Keep us posted
  15. Well it's not that flexible. But it's not rigid either. With a 24" cable, I am able to connect the Ref-10 to the MC-3+ USB which is sitting right above it. This is very convenient. The look and feel of the cable is more of an industrial/scientific instrumentation than of a fancy HiFi system. But I am not looking at the cable, just listening to the benefits of the Ref-10... Hope this helps
