  1. Thank you for this precision. This removes the uncertainty surrounding the PSUs. What remains a mystery to me is this: I sincerely do not have the perception that the Ref-10 is affecting the transparency in any way. Apart from the smoothness you are referring to, it also brings a lot of additional dynamics, both macro and micro in my systems (I actually have one Ref-10 on my 2 systems, with similar benefits). Have you checked whether your femto clock upgraded Lyngdorf DPA-1 is processing the time signal of the S-P/DIF input or if it applies its own time signal ? Might
  2. Here is the reference of the cable I am using for this application: https://www.pasternack.com/bnc-male-bnc-male-rg216u-cable-assembly-pe33403-24-p.aspx
  3. Hi @Confused, Not on the same page with you here. @afrancois was speculating that his LPS-1 was too good for the MC-3+ USB to be further susceptible to improvement by the Ref-10. If the 75 Ohm cables were the only ones to blame here, @afrancois would not complain about a lesser transparency when the Ref-10 is in the loop. This lack of transparency is not caused by the clock IMHO. I once added to my system an Iso Regen which had been let to me, powered by my LPS-1 with the stock energizer. The transparency was very adversely affected. I then powered the Iso Regen with
  4. A few remarks here: In general, and this has been observed by multiple listeners, including @romaz, the better the LPSUs in your installation, the more transparent the sound produced and the more the effect of additional improvements is perceptible in my own installation, I am using a Paul Hynes LPSU to power the MC-3+ USB, and I started to notice very significant improvements in terms of transparency at this stage I have A/B tested various devices powered by the Paul Hynes and by an LPS-1 from Uptone. And I have to underline that the LPS-1, when powered by the stock energiz
  5. Nothing wrong here. Just add (in this case subtract) the level which is necessary to obtain a simulated measurement comparable with the original one. On my own system, I subtract 110 db in REW after convolution, but I suspect this is dependent on the level used to make measurements.
  6. A few things worth remembering at this stage IMHO: this is an interesting source of inspiration about these transformations: https://www.head-fi.org/threads/the-diyrs-cookbook.781268/page-73#post-13459530 Mutec has not been very encouraging about these modifications. Anyhow, from here and there, we could grab the following information: it is mandatory not to exceed 6V (extreme max is 6.2V). Unless, the circuits of the MC-3+ USB which are not protected, could be damaged it is better to unsolder the SPSU as, if remaining, the second stage of the SPSU could be act
  7. Congratulations and glad you like it. You might have noticed that the LPS-1 was a very good filtering PSU, but was very sensitive to the energizer used. If you have the opportunity, I would suggest you test an LPSU as energizer for the LPS-1. You might even be further impressed.
  8. I made this experiment and was not convinced by its benefits. The magic of the MC-3+USB, and even more when it is synced with a Ref-10, is to enrich the listening experience while giving to the music a very natural and analogical presentation. On the other hand, the DigiOne I listened to was enriching the listening experience (more information, better separation, aso), but was still presenting the music in a very digital way, with more harshness if I can say so... I have not been able to suppress this harshness using an MC-3+ USB, although it was synced to a Ref-10. If you are keen to mov
  9. I agree with you. Why not ask Mutec if they are prepared to modify the MC-3+ USB for you ? The more they receive requests in this direction, the clearest they will receive the message that they need to offer a DC input for free as an alternative.
  10. Unfortunately not. But you should not exceed 6.0 to 6.2V as the input tension because the circuits are not protected. Current drawn is around 0.35A. Please remind that all these mods are voiding guarantee as Mutec is not supportive of them.
  11. Interesting. This is putting you on the tracks for the Ref-10
  12. A few observations I made on my own: 1. On my main system, which is now MacMini -> sMS-200 Ultra -> tx-USB Ultra -> Mutec MC-3+ USB -> Devialet D900 -> B&W 802D3, with sMS-200, tx-USB and MC-3+ USB clocked by the Ref-10, I observed an improvement when cascading a second MC-3+ USB after the first one (the MacMini, both MC-3+ USB and SOtM devices were powered by a Paul Hynes LPSU). In the same way that the addition of the tx-USB was an improvement but not a game changer, the addition of the second MC-3+ USB is an audible improvement, but at least one order of magni
  13. Here is an interesting review I found on the German forum. Worth reading IMO. I share the findings of the reviewer, including his remark on fancy cables https://translate.google.com/translate?sl=de&tl=en&js=y&prev=_t&hl=en&ie=UTF-8&u=https%3A%2F%2Fwww.hifistatement.net%2Ftests%2Fitem%2F2119-mutec-ref-10&edit-text=
  14. Sorry to read about this. The way you put it, it looks like a HW defect of the selection knob. You should probably contact Mutec directly for this: https://mutec-net.com/kontakt.php While you were trying to add a second MC-3+ USB in the chain, have you tried to use the WCLK 1-2 out of the first MC-3+ USB in order to feed the second one and check if you could reclock using this external clock signal ? Not sure if this works, but worth trying in order to avoid being frustrated while the Ref-10 is fixed...
  15. You just need a short AES/EBU cable between the AES output of the first unit and the AES input of the second. You will need to set the second unit on the AES/EBU input, as you are used to do when capturing the input from you transport.
  16. Thanks to @mourip for the heads-up on these BNC terminations. The difference with the caps @beessy has found is most probably linked to the fact that BNC terminations will ensure a perfect impedance balance of the electric circuits whereas the caps will not. What would be useful from @julian.david is to know whether such terminations on unused BNC connectors are important for the proper operation of the Ref-10. Thanks in advance.
  17. Thanks for pointing this out. I normally do not feed DSDs to the Mutec and convert them to PCM inside Roon. BTW, is the MC-3+ USB good at handling DSD -> PCM conversion ?
  18. Here you are: you just need to select 'Extern Re-Clock' with the Select button instead of 'Intern Re-Clock' when using the internal clock of the MC-3+ USB
  19. Why not source a cable with an RCA connector on one side and a BNC on the other. Not necessary an expensive one: https://www.thecableco.com/Product/S-Link
  20. In order to try and come back to the roots of this thread, which are to evaluate the interest of a Ref-10 high stability clock in the context of sound reproduction, I would like to remind a few things: the debate between proponents and detractors of external clocking technologies does not seem to be a new. According to this article (http://pinknoisemag.com/pink-papers/pink-paper-002), it has longingly opposed technicians to practitioners in the pro-audio industry and is probably not closed. a long cohort of satisfied customers have made the observation that the Mutec MC-3+ USB was
  21. Thank you for your contributions which are elevating the technical debate. Very useful IMO.
  22. Seems they already did it. Interesting to note that Mr Lee specifically mentioned the tx-USB Ultra in his comment.
  23. Good idea ! Actually I had the same thought. Packaging the good LPSU of the Ref-10, a down-scaled Ref-10 with only one or two clock outputs, and one or two MC-3+ USB into one single box would be awesome. Would save some cable and allow for a 1st class reclocker all-in-one
