  1. I don’t recommend using the LPS 1.2 with the EtherRegen. Though it technically can power it, from my testing the EtherRegen sounds better with a higher amperage power supply. Even the stock SMPS sounds better than the LPS 1.2, but ideally a higher powered LPS like a Uptone JS-2, Paul Hynes SR4T or Farad Super3.

  2. For those who have been playing with the Buffalo switches, has anyone compared a set of two Buffalos vs just one Buffalo daisy chained via fiber with an EtherRegen? I have a BS-GS2008 that sounds really good replacing a low cost (John Swenson recommended) Cisco switch (properly grounded to shunt high impedance noise) in between modem/router and endpoint, and I'm thinking of taking the plunge to a double-switch solution. I'm just trying to decide between the two sets of options above. I would have one of the switches powered by an LPS 1.2, and the other powered by a Vinnie Rossi
  3. Alright, I just installed the mconnect lite app, and it appears to connect to both Tidal and Qobuz just fine, and to play through the UR. I guess I'll just use that for the time being until Linn's apps start working again.
  4. Anyone else having problems for the past couple days with accessing Tidal through Linn Kazoo? I'm a longtime owner of the UltraRendu and have been using it with Linn Kazoo/Tidal for 2-3 years now. Have had little issues in the past that were usually cured by restarting the UR or restarting the MPD/DLNA in sonicorbiter. Those aren't working this time. Two days ago I suddenly lost catalog access to Tidal in Kazoo. Trying to log in to Tidal produces long wait screens and it never logs in. I just resubscribed to Qobuz to give that a shot, in case it was an issue with Tidal, and no
  5. Actually, the shielding doesn't cover all effects. Star quad still benefits in rejecting magnetic interference beyond what shields can do, or so says Benchmark: https://benchmarkmedia.com/blogs/application_notes/116637511-the-importance-of-star-quad-microphone-cable Quote: ELECTROSTATIC SHIELDS DO NOT BLOCK MAGNETIC FIELDS There are a variety of different balanced microphone cables on the market. All microphone cables are designed to provide shielding against radio-frequency (RF) interference. The conductors are twisted and then wrapped with foil, a spiral o
  6. Ok, after 8 pages of debate about the best way to tighten a screw, I have something actually substantive to report regarding sound quality impressions and DC cabling. I've just finished a somewhat extended comparison between short (<6") cables made with 12awg solid core from the hardware store ($.69/ft) both with and without Kemets on each end. This is between my LPS 1.2 and UltraRendu. So, it's a bit simpler system than some of the others discussed on here. I do have a LDover LT3045 board in the house, but haven't yet hooked it up. I wanted to get a handle on my preferred c
  7. Since you have two LPS-1’s, I think you can run them in parallel to double the current to 2A at 5V. Given the latest report on current demands, that might be enough? Is it really limited to 5V? If it can take 12V, , then you can get by with less than 1A, and the LPS-1.2 would work. This is the case with my router. LPS-1 can’t power it, but LPS-2 can because of getting up to 12V input the router’s current demands are just below 1A.
  8. Cornan, can you describe your reasoning behind joining the shield loops of the two DAC cables? Why wouldn't just JSSGing them each individually be just as good - or even better?
  9. I found this interesting paragraph in Wikipedia on Heaviside: Between 1880 and 1887, Heaviside developed the operational calculus using p for the differential operator, (which Boole[10] had previously denoted by D), giving a method of solving differential equations by direct solution as algebraic equations. This later caused a great deal of controversy, owing to its lack of rigour. He famously said, "Mathematics is an experimental science, and definitions do not come first, but later on."[11] On another occasion he asked somewhat more defensively, "Shall I refuse my dinner because
  10. I think what we have here is a simple case of removing one bottleneck in the system and revealing another. If the noise of the regulator/output device is higher than that of the noise pickup in the cabling, I would agree with all of the skepticism expressed. But the quality of these regulators is now at a point that this is no longer true. These LT3042/45 devices are so low noise that now the noise being picked up in the cabling connecting to the load is the dominant feature in the noise profile, thus making all of these cable changes quite audible. A good
  11. @Quadman, what you describe sounds pretty good to me. As my own system has gotten more refined and the perception of music has fully detached from the speakers, I’d describe a very deep soundstage as well, and music usually coming from behind the plane of the speakers. Yes, I’m sure with more incisive and aggressive speakers, I could make the soundstage move forward, but I tend to reject the sound of these kinds of designs as overly emphasizing upper midrange and high frequencies at the expense of the all-important (to me) “power” region of lower midrange and upper bass that gives music its so
  12. Supra considers their air infused dielectric to reduce capacitance of their wire. Capacitance is important to minimize in audio interconnects (i.e. at low frequencies) - correct? I realize this may not have anything to do with DC, but still thought your point about having no effect at low frequencies seemed off.
  13. Any chance this is similar to benefits from Litz wiring? I’m not too fluent in the specifics of Litz benefits, and maybe they’re just for AC and not for DC? But if they do apply to DC conditions, maybe that’s part of the story? Doesn’t that have to do with reducing skin effect? And the multiple sets of twisted pairs further twisted around each other might give us a similar benefit? Whether or not Litz effects are at work, my money is on this being a simple matter of better shielding and wire geometry for rejection of noise.
  14. Well, we have a ton of differences between our two implementations, so no need to even get into the different ears/different goals stuff. Just the differences you've explained are enough to make my head spin: Me - straight DC cable swap between LPS-1.2 and UltraRendu > USB DAC input - no further tweaks You - some kind of power supply > PoE > LT3045 > Canare 4s6 > iDefender > Singxer F1 > SPDIF DAC input These are very different power chains, feeding very different system implementations. The LT3045, iDefender, Singxer F1, and whatever DAC you
  15. Its absolutely not an apples to apples comparison. It’s been at least a couple pages back in the thread, not sure exactly, but the original initiator of this tweak Rob was posting on this thread claiming the evolution to the Supra Cat8 approach developed by Charles on this thread would not sound as good as the original suggested PoE adapters with cheap Ugreen Ethernet cable. He was saying there was something magical about the flat Ugreen geometry that was superior. I doubted him, but given that I already had the original referenced PoE adapters in hand, I splurged and ordered the $6 Ugreen fla
