  1. Try 7v. A couple of Farad users preferred this. However it maybe something particular to the Farad and not the ER.
  2. Anyone tried those Sonore SGC power supplies with the ER? Or the CIAudio supplies? These might be the sweet spot in terms of price - performance. If they sound good...
  3. I haven’t really started exploring power supplies with the ER apart from a couple of experiments which showed to me that different supplies have a small but definitely noticeable effect. here is what I have tried in increasing quality, worst on left, best on right. Stock supply < LPS 1.2 < Welborne Linear < JS~2 The surprise here was the old Welborne linear which I was using on my router. It is no longer available but is a simple floating linear cheaper than the LPS and of course the JS-2. The least surprising was the JS-2 which I usually find the best wherever I put it. Practicallity aside I would just love a rack of JS-2 for everything, but I don’t have the space for another JS-2, and it is a bit overkill IMO especially when the old Welborne sounded a hairbreadth less for a fraction of the price. So I will have a look at for more mid level linear supplies to replace the Welborne (which is currently my default for the ER) but might just spring for another Farad3 for this particular application. Oh and the audible difference going from left to right was improved upper frequencies, cleaner more organic sound, and more relaxed but punchier mids and bass. Also used a separate ER ground with all supplies except the stock.
  4. Very interested in exactly what cable is your favorite? Is it a Belden Cat8 with floating shield at both ends? Can you provide a link to the exact one?
  5. @Jud I couldn’t write a reply (above) to a quote from my phone, but I wanted to say that I am very eager to hear your findings with the Ghent.
  6. Yes that is that is what John S. suggests as well. however for whatever the reasons, (maybe not shielding related), my Cat6a with floating shield, sounds clearly better than the Cable Matters with tied shields from B side to Ultra Rendu. It’s the biggest improvement I have yet heard in my limited testing of ethernet cables. Since Cable matters sound toxic to me, I might sacrIfice one and untie the shield at destination end at some time and see what difference that makes
  7. Identical experience here. Started with a Belden Cat6 cable from Blue Jeans with generic plastic plugs from ER to ultraRendu. Not sure if it is the shielded or unshielded version. Tried the Cable Matters for a month, it had slightly better mid bass but I slowly drifted away from the music. I thought the honeymoon period was over and the effect of the ER was fading. Put the generic Cat6 back in, and the magic is back. Did some repeated AB between the two and I would characterise the Cable Matters as rolling off the very top end, compressing and hardening the lower treble. The midrange spatiality which is the major benefit of the ER was lost thing and sound was not pin point precise anymore. The slight mid bass support this sounded blurred and muffled in comparison. The generic CAT 6 seems far more linear, open better highs and better lows and bass was extremely details and very low bass was better. YMMV, different systems etc, but what is better for some can be worse for others.
  8. Just a quickie, finally plugged something else into the A side. Hooked in my Apple TV 4K which feeds my AV system. Didn’t notice any video improvement, but the audio is definitely smoother. It’s had a roughness that iv e noticed since upgrading my receiver 12 months ago. Now noticeably smoother sounding.
  9. Thermal issues, or non-issues, aside, do people find that specific voltages sound different/better? From the same supply even? I seem to remember John mentioning that different voltage/power supply combinations could sound better. Maybe that was a microRendu thread? Or was it the EtherRegen, or both? One poster indicated a feeling that a 7 volt Farad supply had a slight edge over the 12v Farad. Has anyone else noted a audio quality preference for difference voltage inputs?
  10. I am poised to get another Farad for the ER. How would you describe the differences to the stock supply? And which voltage did you go with? I can’t decide between the 7v or 9v. Also re cables, I have 2 Gotham’s unused as they add midrange richness but also crunchy highs which I couldn’t live with. The Canare 4S6 was more neutral but light on bass and underwhelming. The best low cost cable for me is the Canare 4S8, which is a higher gauge (thicker) version of the 4S6. No negatives. But I haven’t tried the Audio Sensibility Silver...
  11. In one of these threads John mentions that it’s usually capacitance requirements for the PHY to work properly to need >1m ethernet cables, but with the ER he has compensated with capacitance in order to support shorte cable lengths.
  12. 😁 Great idea! I had a heat sink just like yours sitting on a shelf. It was previously used for a wireless router that got a little too hot for my liking. Still has some thermal paste on the underside. Without reapplying any more I dropped it on top of the ER. It’s a perfect fit and definitely brings the temperature down a little.
  13. Hehe, thats what Ive found everywhere I use the JS-2. Its the best for my DAC and ultraRendu too. Im needing a separate rack for all of my power supplies. 🤗 Im waiting to hear some more feedback on the Farad with the ER from user @incus who has this combo. If I spring for another Farad I will try the JS-2 and the Farad on both the ultraRendu and EtherRegen and see what combo works the best.
  14. Oh! I’ve never actually used the stock power cord into the stock power supply. Ive always used a DIY shielded 14awg Belden cable with brass pin plug. Thanks for the reminder, I will roll some cords into the stock supply and have a listen.
  15. Will report back. Knowing the sound of the Farad power supplies, I have a sneaking suspicion that they might be the perfect fit for the ER. And the other variable that was added to the system with the ER was the short Belden Cat 6a that connects the ER to the ultraRendu. It has never been used, so what is the sound of that cable and what is the sound of the ER and what of these burn in changes is the sound of one or the other?
  16. @Lucie Very interesting. I have similar findings. I’m only day 5 in burning in, but I found that initially the ER added an exaggerated spatiality due to pushing the midrange and highs forward. I knew there were changes from burning in so I’m sitting tight and almost relieved that the tonal balance is becoming more normal and the spatiality is less sound effecty. Ive held off tweaking too much until things settle but have tried powering it with a JS-2 and LPS 1.2. These did add some improvements in treble but had a more congested mid range. With the LPS it’s like the bass information was pulled up into the midrange, not in a good way. The JS-2 had promise but I will come back to that when things settle a bit. My current preference is the stock supply, on a circuit separate from the audio system. I’m still having unnatural highs, but so have others until later in burn in process. Overall it’s a definite improvement, but comes with some exaggerated negatives at least initially. Not trying to be negative, just objective amongst almost universal praise.
  17. Are there any disadvantages / advantages to using different input voltages to the ER? Is more heat generated using higher input voltages, being regulated down? im in a hot part of the world with temperatures over 120 Fahrenheit due in the coming months, so I will go for whatever keeps things cooler, unless there is a compelling reason to do otherwise...
  18. Very interested in any subsequent findings you have had, especially the characteristics the Farad fought to the sound?
  19. How would people characterise the changes they experience in sound over 200 hours burn-in? What changes and when?
  20. My system is wireless endpoint to ER, to UltraRendu, to DAC. The UltraRendu is on its own JS-2. I know if I put the ER on the other output of the JS-2, it is not recommended, shared 0v etc. But what if the other JS-2 output was charging an LPS 1.2? And the LPS 1.2 powered the ER? Would this break the shared 0v and be OK?
  21. Exactly, Rob Watts the designer of the Chord DACs, believes we are more sensitive than that and attributes part of the success of his upscaling products to providing 1.3us accuracy. https://www.head-fi.org/threads/hugo-m-scaler-by-chord-electronics-the-official-thread.885042/page-503#post-15076324 And what characterises his products? Clean accurate soundstage with delicate reverb and transients. The descriptions I hear of the EtherRegen are remarkably similar to the benefits of Chord products. He is often quoted as saying high sampling rate is mostly about transient accuracy and resultant reverb and soundstage as opposed to frequency response. And would microsecond precision between channels be shown in those gross low resolution charts over at ARS? Of course not. So my opinion is that part of what the EtherRegen does is removes noise or influences that affect timing of the reproduced analog signal downstream.
  22. Depending on the equipment being connected shorter lengths may work. The 1m rule is to make sure there is enough capacitance for the PHY tranceivers to work correctly. Some switches add capacitors to make sure shorter lengths will work. Some do not.

Tom Petty sings about Batch 1 owners Oh baby don't it feel like heaven right now Don't it feel like somethin' from a dream Yeah I've never known nothing quite like this Don't it feel like tonight might never be again We know better than to try and pretend Baby no one could have ever told me 'bout this Tom Petty sings about Batch 2 & 3 Orderers The waiting is the hardest part Every day you see one more card You take it on faith, you take it to the heart The waiting is the hardest part
  24. I think that might defeat the purpose of the ER. RFI-noisy general purpose computers are some of the things the ER is meant to separate your DAC from. You could attach it to the B side of the ER with your DAC on the A side which would work well. But since computers transmit airborne RFI as well, I would also try and keep the computer as far away physically as possible.
