  1. Make sure to twist them in the right rotation. (Yes there is a correct way and an incorrect way)
  2. Has anyone used the Synergistic Oranges in the JS-2 Power supply? Worthwhile audible improvement? Is the standard rating enough? @Superdad What is the fuse Size and rating for a 230V JS-2?
  3. Another vote for the Oyaide neo Class A (not S), ridiculously good for its price. In Australia you can get it for around AUD$55inc GST and postage from storeDJ.
  4. Are there any benefits with native DSD playback over DOP DSD? Lower bandwidth to DAC? I saw somewhere, and it may be inaccurate, that my Chord Qutest can accept DSD512 via native a USB but only DSD256 over DOP, could this be true? Could lower datarate for the same DSD files have any audible benefit?
  5. Try powering the ER directly with the SR4, remove the LPS altogether, you might find that actually sounds the best 😉
  6. I think Jud did upgrade from the Cable Matters CAT8 to the Belden CatSnake CAT6a with JSSG360 shielding from Ghent. Don’t know if he has moved on from that. I might have to buy one of the same,
  7. At least a couple of people who compared the 7v Farad with higher voltage Farads With their ER and found that the 7v sounded a bit better. Should be back in this thread somewhere. Cost is the same should be easy to change the order. Unless of course you had a 12v application elsewhere that wasn’t the ER?
  8. Remember to get them to also quote on the separate deluxe version with the JSSG360 shielding. 😁
  9. Apart from the Chord Dave DAC, all Chord DACs and the MScaler decimate all DSD to 705khz PCM before doing anything with it. My guess is that the downsampling is pretty simplistic so any upsampling of DSD will most likely be a waste and thrown out anyway. Reading the responses above - what ECWL said. Note that the DAC designer mentioned that 90% of the processing power of the DAC was spent doing the first stage upsampling (the WTA1 filter) and that the second upsample stage (the WTA2 filter) the remaining processing. Which is why offloading this to a massively more powerful processor, either the Chord MScaler or other sophisticated external PC applications (Signalyst etc) makes sense to get it to that 705khz / 768khz stage. Note that it has to be a pretty good external processing to better the Qutest WTA1 filter, that is upsampling with Windows/Mac sound managers or Roon, will likely make it sound worse...
  10. Im using a Farad3 power supply at 7v. The Farad are not user adjustable, I went with 7v based on a couple of other people’s reports that the 7v sounded better when compared to the same supply at higher voltages. This probably only applies to this exact supply and not other supplies.
  11. I think a couple of people might have mentioned this earlier. i don’t believe the power supply (Farad3 @ 7v) I use for the ER has a floating ground, so I don’t have the ER grounded using its grounding screw. However A grounded alligator clip I was using with the JS-2 it was still lying next to it and I thought what the hell and put the alligator clip on the ground lug. It sounds better with the ER grounded!? Definitely better highs. Does this mean the Farad has ground floated? I don’t think it does, so how could this make an improvement? Anyone found that grounding the ER sounds better even if the power supply is not floating?
  12. System synergy YMMV etc. I found the exact opposite. I found the Cable Matters CAT8 on the B side constrained and flattened the sound. Going back to a ‘generic’ Blue Jeans Cat6a opened the sound up considerably. Maybe that Blue Jeans Cat 6a shouldn’t really be considered stock though. Edit: oops sorry, just read Superdads, don’t post about ethernet cables AFTER I posted.
  13. If you have the discipline, let the ER burn in for a good 250 hours before any tweaks. I found that things I needed to address or compensate for, go away after this time, after which you really know what you are dealing with. After that, my biggest improvements were a good power supply and Ethernet cables with floating shields on both sides, even B-side.
  14. Hang on, if a single supply is powering both ERs, then the separation between them is lost, so much of the benefit of the upstream ER is gone. What is the other rail powering? (It shouldn’t be anything downstream of any ER)
  15. Upgraded power supply for the ER from an old Welborne (which sounded good, almost as good as the JS-2 for this particular application) to a 7v Farad3. Noticeably better than the Welborne. Losing the desire to test any other combinations, but at some stage might swap the Farad out with the JS-2 to directly compare. From memory alone I would characterise the difference being that the JS-2 is a bit more natural and organic and the Farad as a bit cleaner and punchier. I am still amazed that power supplies (And DC cables) this far up the chain are so noticeable, but they are in my system. Another note about those SMPS wall warts, yes I know many measure well, especially the ground shunted ones, but despite the measurements, removing any/all from the audio system always makes it sound better.
