  1. OK thanks. Yeah I wasn't sure if it was going to take weeks, months or years to deteriorate? Regardless, this cable has made quite a remarkable difference in my system and has put cables as a higher priority on my to do list. At some point before the years end I am thinking of investing in some better speaker cables (possibly tellurium q black II), ac cables and maybe an audio sensibility silver dc. Might have to wait for my birthday as an excuse ๐Ÿ˜‚
  2. Thanks for this. I did wonder how long it might take for the copper to deteriorate after I stripped the insulation off. I didn't know that about silver oxide still being highly conductive. Great info, thanks ๐Ÿ‘. Are your interconnects DIY? If you have any pics or further info I would be interested ๐Ÿ˜Š
  3. My latest adventures with dc cables. Recently I was revisiting the first post in this thread with the brilliant collection of links that Rajiv has put together and I started re-reading one of the posts by romaz about power cables. Here is a quote from that post where he talks about dielectrics. "Here are examples of the dielectric constants of various materials: Air (vacuum) 1.0 Cotton 1.3 Wood 1.4 Teflon (PTFE) 2.1 Polypropylene 2.2 Kevlar 3.5 Neoprene 4.0 Distilled water 34 Teflon and polypropylene are the most commonly used dielectrics because of their durability and heat resistance. Certain manufacturers have gone to cotton as a primary dielectric (i.e. DHC, Zenwave) and I believe their results speak for themselves.๏ปฟ๏ปฟ๏ปฟ๏ปฟ๏ปฟ๏ปฟ๏ปฟ๏ปฟ๏ปฟ๏ปฟ" This got me thinking about something John Swenson said with regards to how dielectric absorption can effect the performance of a dc cable. Previously I have used chopped up bits of an audioquest ethernet cable with good quality solid core copper inside. A while ago I used all 8 conductors for a positive and all 8 in another section for negative. The results were underwhelming and I went back to my 10awg wire trimmed at each end to fit my plugs (in separate positive and negative wires). I wondered if all the insulation on each conductor was having a negative effect. So I stripped the insulation off each conductor. Then I wound 16 of the 28awg conductors together and using the handle of a cotton shopping bag (once cut it makes a nice cotton sleeve) I twisted the cotton sleeve around the conductor and used electrical tape to hold the cotton on. Ending up with a positive and negative each looking something like this... So I have 2 x 16 x 28awg. The positive is around 10cm long and negative is bit longer. I then did separate JSSG 360's around the positive and negative and put it in place between my lps1 and sMS-200. The end result is a very ugly looking "cable". But looks can be deceiving because this is by far the best sounding dc cable I have made. Everything sounds richer and smoother with better tone. Vocals have more of a sense of realism. Every note on the piano is better delineated from the other keys being struck. Brass instruments are less harsh and have better timbre. I think there is also a darker background with more depth and better image focus. Is anyone else using cotton as a dielectric on cables in their system?
  4. Thanks again to @romazfor another amazing, comprehensively detailed and riveting post. Thanks also to @austinpop for your ongoing jovial maintenance of the thread. I love this thread ๐Ÿ˜. I find Roy's recent post very exciting with regards to the gains that can be made at the switch. I have, for a long time, hoped that uptone and others would produce a switch that could make up stream changes irrelevant and I hope that John can achieve this with the new EtherRegen. I have similar questions to @Johnseyewith regards to the nuc and how it would compare to a ultrarendu or similar where the os is already on an sd card with sonicorbitor fully loaded to ram on start up. So the difference to me seems to be the switch and the direct connection protecting the end point from other traffic. From what Alex has said about the EtherRegen, the end point connection will have it's own clock and will be protected from other network traffic, so hopefully that makes a direct connection redundant. Also, @romaz, did you try the new sotm switch outside of the direct connection and did the direct connection still impact the sound with the new sotm switch? Exciting times ahead ๐Ÿ˜๐Ÿ‘
  5. Thanks for this comparison Rajiv Do you know if anyone has done a comparison between the audio sensibility and other high end dc cables? (such as zenwave or others) I'm just trying to figure out some rankings as I'm considering having a dabble in the high end dc cable market as it may well yield better results than my feeble DIY attempts๐Ÿ˜๐Ÿ˜…
  6. I put a JSSG 360 on my interconnect between dac and amp and got a very nice improvement. More colour to the music and a slightly blacker background
  7. 1. He is just twisting a few of the frayed ends together - really though, all that is required is contact between the two layers however a bit of pressure from some tightly wrapped electrical tape and twisting some frayed ends together is probably a good idea ๐Ÿ‘. 2. Ideally you don't want to make contact with the plugs. The idea is to wrap a Faraday cage over the cable without any electrical conduction between the cable and the shield. Probably best to cover your plugs with some insulation like some tape first. 3. I have a curious cable and just wrapped the whole thing in one JSSG 360 4. I have done this to my curious and didn't bother insulating the 5v cable 5. 3/8" (9.5mm) will fit for both layers. It will expand - if it's a tight fit you can use my chopstick method posted further above. 6. Probably not - but don't go too big ๐Ÿ˜ Also, as the braid expands in diameter it shrinks in length, so cut a bit longer than your cable and then it will get shorter as it expands over the plugs - then longer again once past the plug and onto the cable. Have fun and let us know what you reckon ๐Ÿ‘
  8. Yes, I also have considered this to be a possibility. John Swenson has said that ethernet cables carrying high impedance ac leakage current will be emitting significant amounts of emi/rfi. I am using a gs105 switch with the negative dc output of the power supply that is powering it grounded (in fact it is the sps-500 - it's negative dc output is grounded as long as you are using the 3rd pin on whatever ac cable you are using). This means that the main cable emitting emi near my audio equipment is the one coming from my router to my switch. This is a 10 meter cable and I intend to put a JSSG 360 on the final meter or two of this cable for the very reason that you have mentioned ๐Ÿ˜๐Ÿ‘... I will need some more 3/8" braid for this though. Hopefully I will get to try it at some point in the next few weeks
  9. Interesting, thanks, I will have to google them and take a look ๐Ÿ‘
  10. I live in a semi rural area as well and I am not aware of any solar inverters in my immediate vicinity (however there would likely be some within a kilometre). Despite this I would imagine that my own equipment in my house would generate a fair bit of emi/rfi... I have a number of devices on WiFi and computers and WiFi router all in my listening room so I'm sure there is plenty of interference just within my house. I don't know much about the construction of the big sur cable I'm using but I don't recall reading about it having any shielding, so perhaps there won't be as many gains for those with analogue cables already with shielding. However, there were some nice gains by adding JSSG 360 to the supra cat 8 (as an Ethernet cable) and it is already heavily shielded.
  11. Just to expand a little on what JSSG 360 brings to my analogue cable. On the track September in Montreal by Alison Bisson, listening to the first 30 seconds, there is a cymbal shimmer at the beginning that I have never heard so real with so much detail before. There is a real natural sense of the cymbal shimmering that it arouses a visual picture of the cymbal itself. Funny how I listened for several hours but it's small things like this that stuck in my memory. On another track, the last track on the continental shift album by Slava Gregorian and Al Slavic I noticed a clearly defined synth in the background that I hadn't heard so clearly before or really even noticed despite listening to this track over a thousand times. I'm very interested to know if others have tried a JSSG 360 on their analogue cables?
  12. Absolutely! Highly recommended on my curious cable ๐Ÿ‘Œ๐Ÿ‘ Yesterday I tried a JSSG 360 on my audioquest big sur analogue interconnect between dac and amp. I wasn't sure if this was going to be a particularly good thing, but I am absolutely stoked with it! The music seems to have more colour to it and also comes from an even darker background. I used 1/4" braid to go over the 3.5mm plug (I use a chord mojo dac), however I would recommend using 3/8" braid instead because it is a very tight fit. I figured out that using some chopsticks and taping the end of the cable to them, the braid can be expanded and then it can slide right off onto the cable From here if you just hold the chopsticks and push the braid (with cable taped to the other end of the chopsticks) then the braid will slide right onto the cable ๐Ÿ‘. Another very nice improvement and well exceeds the value of the braid
  13. Yes, as Cornan has discovered there seems to be some sq gains by having the positive and negative wires in separate cables (with some distance between) I made this cable several weeks ago as a test and I can't bring myself to take it out. It's 10awg trimmed at each end to fit in the screw terminals with separate jssg 360 for positive and negative. I first tried jssg 360 just on the positive but there were improvements again with the JSSG 360 for the negative as well. Even with such a short cable JSSG 360 still has a very nice impact on both positive and negative wires ๐Ÿ‘
  14. I'm very interested! What are we looking at in the picture? Is it a double barrelled Gotham with the shields joined together?

    ISO Regen performance Improvement Cheap!

    What output voltages do you have on your boards? What's the input voltage range of the ultrarendu?
