  1. Hi Jamesg11, Yes, but not quite. • 2 x LPS-1.2 to UltraRendu and IsoREGEN • Internet (modem), Mac Mini, NAS-disk through Cisco 2960 switch • Cisco switch SFP (optical) out to EtherREGEN SFP A-side • EtherREGEN B-side to UltraRendu • JS-2 (1) to EtherREGEN, JS-2 (2) Y-DC to Mac Mini + NAS So I guess my JS-2 (and EtherREGEN) connections maintain isolation 😇
  2. Thanks for sharing Soares! What is RUR? And I dont see OpticalRendu (oR) in your setup layout. What convinced me to stay with my current setup is by playing the "Nama" album (24/176.4) with the Puente Celeste ensemble (2010). Its an Argentina-based recording with absolute minimal use of mixing and mastering tweaks and compression - only microphones and artists and recorded at MA-studios with original 5.6 MHz (DSD) pure sterophonic, one bit recording. EtherREGEN powered by JS-2, Cisco 2960 SFP (optical) transporting the signals and IsoREGEN in front of the Denafrips DAC ha
  3. I use a dedicated DC 12V output from Uptone JS-2 to EtherREGEN. Do you think using LPS-1.2 would give better galvanic isolation than the JS-2?
  4. Hi R1200CL and esmit, I tried without the IsoREGEN (between UltraRendu and Denafrips DAC), but to my ears it sounds better with the IsoREGEN. More air and space round voices and instruments, and better depth perspective. What might be able to substitute the IsoREGEN would be a Denafrips DDC using I2S, I think...
  5. Hi esmit, my network is set up in the following order: Modem (internet) > Ubiquiti X-router > Cisco 2960 switch (SFP) > EtherREGEN A-side (SFP) > EtherREGEN B-side > UltraRendu > IsoREGEN > Denafrips DAC. Internet from modem via Ubiquiti X-router, Mac Mini (Audirvana) and NAS-disk has RJ45 connection to Cisco switch. EtherREGEN A-side being fed with a single optical connection from Cisco SFP-port.

  6. Hi R1200CL, Thanks for your comments. I wrote you some thoughts in a Message, please check.. 😀
  7. Until yesterday my EtherREGEN drew its power through a Y-cable attached to one of Uptone JS-2 DC outputs, and sharing 12V with a WD NAS-disk. The other JS-2 DC output was dedicated to MMK-modified Mac Mini (+sense option). Yesterday I received a new set of Ghent JSSG360 DC cables. This time I reserved a dedicated 12V output to EtherREGEN, and split 12V between Mac Mini and NAS-disk with the new Y-cable. A dedicated JS-2 12V output to EtherREGEN resulted in a profound lift in sound quality! Any trace of "digital glare" is gone, I experience more openness and clarity in upper frequencies
  8. A month ago I changed my network setup, integrating a Cisco 2960 (second hand) into the mix. After multiple attempts, I finally succeeded to hardware reset the Cisco so that the high speed ports (RJ45 + SFP) got activated. I got a set of Cisco compatible SFP's form eBay and a 1 meter duplex multimode optical fibre. I connected Mac Mini and NAS disk to Cisco's 100 mbps ports and optical to EtherREGEN SFP port. Internet is provided by a long stretch of Supra Cat8 cable coming from my Ubiquiti X-router. Previously Mac Mini, NAS disk and internet was connected to EtherREGEN's A-side. I also experi
  9. Today it was my turn to experience a mind-blowing and very unexpected lift in soundstage and overall sound quality. While I was behind my system and messing around with cables, I also replaced my single-mode SFP-modules and fiber cable with duplex-mode SFP's and fiber connecting a Ubiquiti router to EtherREGEN’s SFP-cage. I didn't turned power off on any device - just connected the new duplex-mode fiber. Right away I was met by a larger and better defined soundstage. I could hear subtle details that previously had escaped my attention. The musical presentation and separation, especially
  10. I finally managed to connect my Ubiquiti X-SFP router to the audio network and EtherREGEN's SFP-port - by single-mode SFP's and a single-mode optical cable. Coached and instructed by user octaviars until everything was up and running. The trick was configuring the Ubiquiti's SFP-port setup (on browser) - and swapping ends of the single-mode optical cable so that EtherREGEN's SFP was using Blue cable end (UPC) and Ubiquiti the Green (APC). Bingo! So how does it sound? Well, in my system the internet connection via EtherREGEN is actually only for being able to manage my Mac Mini and

  12. Hi octaviars, I have posted a message with some tech questions 🙂 Tom
  13. Thanks octaviars! I'm a network novice and most likely picked the wrong items when shopping. I will connect the Ubiquiti directly to my iMac tomorrow and check the settings for the SFP-port 😕
  14. Thanks John Swenson for your elaborate response! The Ubiquiti X-SFP is an advanced router dedicated for small businesses and offices. It's not plug & play and needed configuration. I chose it from audio user recommendations. The single-mode SFP's and cable was also recommended. The Ubiquiti will accept both single and dual-mode SFP's and cables. But since it's not a big deal, I will first try with another cable (yellow/yellow). I would also like to take this opportunity to thank you and Alex C for your wonderful products, that has brought completely new life into my aged analog tube
  15. I started an optical experiment some days ago. Ubiquiti X-SFP router > EtherREGEN. Ubiquiti’s green LED lights up when both SFP’s and optical cable is connected - but no sign of network, Mac Mini and NAS-disk connected to EtherREGEN. Here is what I use: Ubiquiti X-SFP router (properly configured), with 5 RJ45-ports and 1 SFP-port Ubiquiti single-mode SFP LC-modules (Model UF-SM-1G-S) • Blue (1310/1550nm) • Yellow (1550/1310nm) 7m single-mode optical cable (one Yellow and one Green end): • Type: LC/UPC - LC/APC I connected (firmly) Blue SFP to
  16. Later in the evening, I continued listening to Supra Cat8 (eR B-side > uR) and now it seem to affect imaging and sound stage in a positive way - Pat Metheny's "What's It All About" and Michael Manring's "Selene" (live) sound more organic and natural. The speakers "disappeared" completely. Strange that a 20$ ethernet cable can have such an impact...
  17. Yes! Supra Cat-8 deliver better resolution and bass compared to AudioQuest Cinnamon Ethernet cable after only two hours of action, between EtherREGEN (B-side) and Sonore UltraRendu. I expect more in coming hours. I've also required an Ubiquiti EdgeRouter X SFP. To be ethernet connected between my Airport Extreme (DHCP & NAT) and configured Ubiquiti. Maybe a better alternative to Fiber..?
  18. Thanks! A quick look at eBay and a lot of sellers from India - are there fake Finisar SFP's? Tom
  19. Thanks for the tip! And yes, the opticalModule is what I should have headed for, as it's manufactured with audio use in mind - and I might give it a try later. I had a pre-taste of what optical isolation adds to the system first time I connected the "cheap" FMC, but the advantage turned into degraded sound quality over night... Tom
  20. I hate to confess that the day after I installed a FMC, I noticed my equipment didn't sounded as expected, and certainly nothing near the small "revelation" I heard the day before. 1. I experimented with and without the FMC, and to me it sounded better without it. 2. In Audirvana+ I waited until the song was fully loaded, disconnected the ethernet cable at the FMC, and pressed play. Still no difference. 3. So I exchanged the included SMPS with a LPS-1.2. Still, it sounded better without the FMC. So my humble conclusion is that the inexpensive FMC I bought is not an audio grade de
  21. Yes, the 10Gtek FMC package has a SFP transceiver included. You need another SFP for your connection. Third ingredient is fiber cable at your choice (length)... Tom
  22. Big smile from Norway after installing a 10Gtek FMC between Airport Extreme and EtherREGEN. Noticeable lift in clarity, dynamics and overall performance. Not ground shaking, but certainly a keeper and just what I needed. I ordered https://www.amazon.com/dp/B0716XT1QT (Superdad recommended 3-pack link below) on sunday and plugged it in today (thursday)! Tom
  23. I have two iFi AC iPurifires and I tested both this morning, and they produce same result when attached into the wall outlet: HUM from JS-2. Without iPurifiers and with JS-2 directly into wall - no HUM. In my TV-surround (same room) I usually have one iPurifier attached, and I think I get better sound/picture... Tom
  24. Great discovery! Since I received my JS-2 some three weeks ago, I have experienced an annoying mechanical hum coming from JS-2. I thought it was normal and after reporting to Alex C, his reply indicated that hum shouldn't be a problem with JS-2 at all. So I conferred with forum member "Frojo" who asked for my setup and power connections. Well, I get power to my equipment from a duo wall outlet - one for equipment, and one for an iFi AC iPurifier. Frojo suggested to remove the iFi Purifier and connect JS-2 directly into the wall outlet. I did so yesterday - and swoosh - no hum at all!
  25. Give Al Di Meola and "Pursuit of Radical Rhapsody" (electric/acoustic) a try with your EtherREGEN and other gear. Absolutely mind blowing how the dense rhythmic and highly dynamic sections are presented, and it's a good record for testing your equipment - if you like that kind of music 🙂 With SD-card-booting Mac Mini now powered by JS-2, my system is from another planet...
