  1. One user at AS tried quite a few ethernet cables and found that the Belden 1303 above was his favourite. Jud at AS tried a couple of CAT 8s and CAT6 and bought the Ghent version and has no desire to look any further. I believe all CAT8 (and CAT7?) have shields tied at both ends so these are definitely not recommended for more than one connection on the A side, and for some, myself included, sound bad on the B side as well. For a few who have tried it, cutting or heatshrinking the shield away from the metal ends on the CAT8 seems to ‘fix’ the sound. As mentioned in the previous post going back to a Belden CAT6a (no shields tied) on the B side restored the ER magic, and my CAT8 cables are rebagged and in storage. In time I will definitely try the 1303 aversion of the CAT6a I am using now, probably the Ghent JSSG version, but right now my focus is elsewhere (BNC cables)
  2. Last time I checked, so I’m probably way out of touch, the Gieseler use a separate SMPS to charge/power it? If so I will avoid, as those SMPS seem to be toxic if they come anywhere near my system. Even when I put an SMPS on a different circuit it has an effect.
  3. There have been many similar reports on the AS ‘cables etc’ thread so hopefully some of the feedback is incorporated. Another personal finding - power supplies. Yes many reports have said that the improvement is small but noticeable and positive. I tried my self when I had less than 100 hours on the ER and concurred. But coming back and trying again with hundreds of hours and I’m shocked at how much better it sounds. Much better than when I tried before. The LPS1.2 was meh - better midrange but a forced feel with the bass pulled up into midrange. The JS-2 is great but at high cost. The surprise was an old cheap linear supply (Welborne) that I removed from my router. It was almost as good as the JS-2, however something equivalent is a fraction of the price, less than an LPS 1.2 even. In fact I think that the SMPS that powers the LPS is a major problem as every time it is added into my system, but I digress. Anyway Ive sold my LPS1.2 now. I now believe that a reasonable low cost linear is clear improvement to the ER so Im hunting around for one so that the old Welborne can go back to the router.
  4. No you are right! i know what the manual says and what John Swenson said initially, But a growing number of people are finding that B side cables with shields tied at both ends have a negative Affect on the sound. Myself included despite buying Cable Matters Cat 8 from the USA. It sounded bad, throwing most of the benefits of the ER out of the window. It was like the magic returned going back to Cat6 with plastic ends on the B side. Apparently it’s not the Cable Matters cable per se, just the connected ends, as others have disconnected the shield at one end and then all is good again.
  5. Anyone else had a listen to the new S5 and M8 Michi power amps? Impressions?
  6. They ARE enormous, S5 are the same. Wont even fit on my racks, my already large Multichannel receiver would be dwarfed by them. Anyone else had a listen to these amps? Edit: And especially anyone in Sydney, who has these in stock for an audition???
  7. Dan the designer of the Opto DX is currently working his Stop RF product and has been doing lots of measurements of radiated RFI along with listening tests. One of his findings in his white paper and his suggestions to me in emails is to get rid of all SMPS wall warts. Despite his not able to see any standout pattern in his measurements, his listening tests found the presence of SMPS to be detrimental, presumably from radiated noise. So take this into account when trying power supplies as some linear supplies use an SMPS as a first stage like the UpTone LPS 1.2 (and the Giesler?)
  8. I’ve experienced quite dramatic changes with burn in on other more complex devices and cables but I wasn’t expecting any with the Opto DX. And no user reports I have read suggested that it did. But now a week later you are dead right! It has definitely changed with burn in!! Nothing else has changed in that time but everything is sounding more relaxed. The DX initially sounded rushed and a bit forceful.and fine for some music but not others. Now it is across the board better. I am finally hearing the full effect of the MScaler! The battery charging was awkward at the beginning but it’s part of the process now. Those cheap batteries get 12 continuous play. If you just switch them off when not playing music I only have to leave them in to charge every few days during the week. I’ve ordered a second battery for the TX end as well.
  9. Opto DX in the system now for two days. Change wasn’t as big as many of the anecdotes I’ve read, which I am convinced is because I was already using a high quality power supply on my MScaler. And a major part of what the Opto DX does is stop the massive leakage current from the dodgy Chord stock power supply from getting to your DAC. Plus I had preconceptions from others reporting the effect of the DX as resulting in a ‘smooth’ whilst my findings are that it can be smooth with specific power supplies, but the smoothest combination IMO isn’t the most natural or the best. Its only been two days so my opinions could be the opposite in the coming weeks after living with some of the power supply combinations. Also note that I am fully prepared to unflinchingly buy a new Farad for the RX receive end if that’s what sounds the best. I’ve now tried many combinations of UpTone JS2, LPS 1.2, Farad, Welborne, lithium ion batteries and low noise SMPS on both the Receive DX (RX) and Send DX (TX). Again, no final conclusions right now, but instead a major flag to you @sandrews888 to source a single one of those $50 lithium ion batteries I linked above (which were in turn recommended to me by one of the first DX owners in Australia). If you have an MScaler and Dave I know a $50 experiment is not going to break the bank. At first I dismissed the sound of the battery as being a bit ‘rougher’ than the ‘amazingly smooth’ I had preconceptions of. And the linear supplies on RX do give a smoother presentation. But in comparison to the battery, that smoothness also feels a bit constrained with the battery being rougher but more open and natural to MScaler true sound. Anyway I’ve said to much at this early stage and may flip in my opinions in the coming weeks, BUT trialing a lithium ion battery on the RX side is a must for Opto DX owners to see if it works for them. But give it a little time as at first listen the battery wasn’t my favourite but it might end up being so. At the very least it does something special that the linear supplies don’t.
  10. Opto DX ordered. Another owner recommended the below linked rechargeable supply as a low cost supply that sounds great with the Opto. I’ve ordered one as well, but won’t be able to report back until it all arrives. Thought I would pass the recommendation along. https://www.ebay.com/itm/312795913653 Edit, the voltage regulation isn’t great, so these are not suitable on Chord components themselves, but are fine for connecting them using the Opto DX which is happy with 11-16 volts
  11. Thanks again, I think I might have to evaluate this connection between my MScaler and Qutest for myself. I hope the next Chord DACs will still support these dual BNC inputs also. oh were those 12v supplies you had lying around your house linear supplies or SMPS wall warts?
  12. Does it come with any sort of power supply for each side to ‘trial’ it with? Did you trial with SMPS with the view of updating power supply if you liked it? Or did you have some quality linear supplies at hand? That is if I trialled with SMPS, is that enough to experience its benefits?
  13. I just responded to your post from last week on the previous page of this thread, where you were interested in what equipment I had preceding the EtherRegen. Which is fair enough, as it all seems to contribute as you go up the source chain. Even DC cables seem to matter on components up the chain which is confounding but I’ve stopped trying to look for for explanations and now I ‘listen first, ask questions later’
  14. Digital source is a 2018 Mac Mini running LMS server, ethernet connected to Airport Extreme Router in another room, wifi to another AirPort Extreme high on a shelf in the AV room, ethernet connected to EtherRegen. I hear you about good cables. My cable strategy is always to start cheap and try all low cost options and only go up the spending if I am not happy or feel something could be improved. Sometimes you really find giant killers down in the weeds. Like my Oyaide USB, AUD $55 and is better than cables I’ve tried at many times it’s price. Maybe the Cable Matters at USD$10 will stay in place as well. Here is how someone else rates it from the AS forum “ I prefer it to the WW Starlight. They are very close - which says a lot given the price difference - but the CM cable is better balanced with better dimensionally”
  15. EtherRegen into a Sonore ultraRendu into Chord MScaler into Chord Qutest into Modwright 36.5 (preamp) into Channel Islands D200 (power amps) into Spendor SP 100 speakers.
