  1. Some of the Everest Tape Transfers from the late 50s are jaw droppingly good in sound quality. A couple other labels, perhaps already mentioned, are BR Klassik and Tudor.

    Mutec REF 10 Masterclock

    Apparently our group buy exhausted the availability of 50 ohm BNC connectors in Germany. Who says CA Group Buys aren’t lucrative?!
  3. Another Update on JSSG 360 As I mentioned, I can't A/B just the effect of JSSG 360 on the cables I did yesterday. However, just as a refresher, I re-auditioned several DC cables between my LPS-1.2 and the TLS switch. Of course, this was while streaming music from Tidal, as the switch does not come into play for local files. I compared: Ghent JSSG Canare Furutech FA 220 AWG14 Audio Sensibility UPOCC 7N silver with JSSG 360 In the past I had found the Furutech to sightly outperform the Ghent in my system, and both were outperformed by the Audio Sensibility. Well, these same results still hold, but boy, the SQ improvement from the Furutech to the JSSG 360 Audio Sensibility is now just startling. How much of this is an "extra" boost from JSSG 360 I cannot honestly say, but the trend is promising for JSSG 360.

  5. I'm not sure I'm qualified to answer your question. As I understood it, Larry's approach was also to slide on the braid without removing connectors. The flat issue is orthogonal to that ("that" being whether connectors need to come off). It only came up because unlike other vendors, Electriduct specifies their braid measured flat, unlike others that measure diameter. Someone more eagle-eyed than me noticed it, and pointed it out.
  6. Yeah, I'm pretty pleased with myself. As Larry told me privately: "... nice to see old dogs learn new tricks." BTW one caution: the electric tape for insulation becomes really tedious with long cables, like my 1m Lush. This is where the heat shrink tubing and heat gun probably are much more efficient in time. Maybe I'l try this next time.
  7. Update on this. Since my initial foray was successful, I then went ahead and JSSG 360'd a couple more cables - a 1m Lush that connects my SE to the tX-USBultra, and my Audio Sensibility UPOCC Silver DC cable, that connects LPS-1.2 to TLS switch. I'm hesitant to report listening results, as the methodology is challenging, since I can't A/B with the original. When I reported on the JSSG 360 Lush, I had the advantage of having a second unmodified one to A/B with. In the case of the Pasternack clock cable, and the Audio Sensibility cable, I did not. The best I could do was listen to the unmodified cable (A), then modify it (which can take 15-30 mins), then listen again (B). Even though I trust my ears, I doubt my audio memory is good enough to make these comparisons meaningful. Suffice it to say that these JSSG 360'd cables are sounding very, very good. You might be wondering... does the JSSG 360 clock cable rise to the level of the Habst or the SOtM BNC cables? Sadly... no. Those still sound better. My subjective sense is that JSSG 360 improved the SQ, and closed the gap somewhat, but just as I found with JSSG, there is more to cable SQ than shielding. What I really like about the JSSG 360 approach is that you can take a cable you already like, and then mod it easily for a possible further bump in SQ - like my experience with the Lush. The next cable I want to JSSG 360 is my Paul Hynes DC3FSXLR silver cable. With the arrival of Eric's SR-7 imminent, I can compare my modded cable to one of Eric's unmodified ones. I'll let you know once I do this experiment.
  8. No response, so I guess this is a non-starter. Anyway, if any of you make it to CanJam London, give me a shout.
  9. Sorry, I lost track. What was your question, again? I thought you were asking how JSSG 360 differs from the original JSSG.
  10. Refer back to Larry's post on JSSG 360. The "separate wire connected to each end of the shield," is not a wire, it is a full cylindrical section of tinned copper braid.
  11. Nope - those are craft scissors from when my (now grown) daughters needed them for school projects, and stuff. Honestly, any sharp scissors would be fine!
  12. OK gang - SUCCESS building my very first JSSG 360 cable! To those DIY-phobic readers like me who've been hesitant to try this - come on in, the water's fine. Steps: I started with this generic Pasternack RG-400 50Ω cable I first masked the protruding ends of the BNC connector into the cable with electric tape (green in the picture). I then used a pencil to shape the flat Electriduct 3/8" flat tinned copper braid into a cylindrical form, and then slid the braid over the BNC connector onto the cable. Following which, I applied electric tape over the bulk of the braid, leaving only the ends exposed, as shown below. Note: I used some tension while applying the tape to mimic the effect of the heat shrink tubing. It seemed to work fine. Also, this particular brand tape as shown is quite flexible and did not cause the cable to become resistant to bending as I had feared. Next, slide on the 2nd layer of braid: After this, I "encouraged" the exposed ends of the inner and outer braids to fuse together - not hard, just peel away from the cable and then finger twist the wires of both braids together. I then used the silicone rubber fusing tape - awesome stuff, excellent hint by @mozes - to seal the fused ends of the braid. This tape is stretchy, so it helps to apply some tension when applying it, and it just fuses nicely. Final step, slide on the wire sleeve for a nice finished look, and seal with the fusing tape. End result: I'll be doing some listening this evening, and will report on how it sounds. Exciting stuff!

    Innuos Zenith SE MkII

    Yes, that’s correct, although I suppose it would work for an external Core too.

    Innuos Zenith SE MkII

    Just a quick heads up to fellow Zenith SE owners. If you're like me, where you're committed to Roon, but have noticed that the internal squeezelite player sounds better, Innuos may have found a solution, where we can have our cake and eat it too. Nuno had me test an experimental build on my system, where the squeezelite (internal player) daemon has been modified to work as a Roon endpoint. So basically, in Roon, you select the Squeezelite (internal) player as the target endpoint! Here is what I learned from my listening experience: The SQ of the squeezelite player from Roon was identical, or as good as, the normal mode of LMS/iPeng. So that is good. Since Squeezelite is supposed to be able to handle up to 24/384 (as per https://en.wikipedia.org/wiki/Squeezelite), there is a puzzling 192 limit in the Roon device setup. This still needs to be investigated. For me - I do have some DXD, and DSD128 content that I do not want to play downsampled. But it's not a showstopper. I can always switch back for these albums. Playback is not totally glitch free. Occasionally - it happened to me every few minutes - the stream will abruptly stop. If I hit play again, it will resume fine. I am guessing it is some fragility in the LMS emulation in Roon, but who knows. Again, not a show stopper. One clear advantage this mode (Roon->squeezelite) has over the iPeng/LMS approach is that you can stream MQA from Tidal no problem. I was able to set the Squeezebox device properties in Roon for MQA to "Decoder and Renderer," and the MQA stream passed through perfectly to the Mytek DAC. The outdated Tidal plugin in LMS only allows 16/44.1, so it messes up MQA. Innuos still have to come up with user controls (toggles in the Server Integration UI) to enable this, but I've enthusiastically recommended to Nuno that they deliver this as soon as feasible.
  15. Indeed! I too have found DC cables to matter. The DC cables I used were already optimized for the PSU's. After much experimentation in the past with starquad, JSSG, etc, I have found silver UPOCC cables to sound best in general. So here are the cables that were used with the various PSUs: SR-4: Paul Hynes's DC3FSXLR silver cable LPS-1.2: Audio Sensibility Silver Signature 7N UPOCC silver cable sPS-500: SOtM Stranded 7N UPOCC silver cable JS-2: both the stock Uptone Belden starquad cable, and the Audio Sensibility cable. I am aware of all the recent DIY experiments going on with POE injectors, JSSG 360 etc, and will certainly experiment with these once the dust settles a bit.
