    Using Power Conditioner to eliminate Noise carried over Ethernet

    Well the cable you bought (Cisco SFP-10G-CU1M) is not even fiber optic. That’s a Direct Attach Cable—which is dual twinaxial copper terminated to an almost empty PCB inside the SFP shell. They have their uses but provide zero galvanic isolation. Anyway, that module advertises itself— to...

    Using Power Conditioner to eliminate Noise carried over Ethernet

    What SFP transceivers are you using? The one in the Cisco needs to be one coded for Cisco or it won’t work.

    SOtM sNH-10G Network Switches x2 : The NEW KING of USB/Network Gadget Setup

    Sorry but that will not work. The “Word-Sync“ clock output of MSB’s S/PDIF interface is an audio-sample-rate rela frequency. The external clock input of the SOtM switch accepts only a 10.0MHz reference clock.

    AppleTV X - I am playing with something new

    Hi Chris: I think you may have been away in December so perhaps overlooked my below questions. I’m still curious. Thanks. ====== December, 2023 Hi Chris: Alex from UpTone here. I am just now catching up on your success since our technical conversations via phone and e-mail back in April...

    Network Acoustics - Tempus network switch

    Then please remind us why you hanging out and posting in threads about audiophile switches. :rolleyes: And based on the diagram of all the devices in your digital chain you must believe in some of the underlying factors which impact packet-data interfaces. Otherwise you have spent a LOT of...

    Good mid-price audiophile switches

    100Mbps is fine. And with EtherREGEN Gen2, 100Mbps endpoints (or 2-pair cables, or OS settings that force such) connected to its newly 1Gbe-capable 'B' port will negotiate to 100Mbps just fine. But for us, through our use of a new exceedingly low-jitter and low-power PHY (just 6mm square)...

    Good mid-price audiophile switches

    Thank you for your interest in the award-winning UpTone Audio EtherREGEN switch. It is easily the most radical and successful component we have designed to-date. As you may have read, we have been working hard in development of EtherREGEN Gen2 for over 1 year—utilizing more readily available...

    Good mid-price audiophile switches

    Thanks and true. More specifically, we use high-speed, low-jitter differential digital isolator chips to pass SGMII Ethernet—and two frequencies of differential clocks—across a PCB gap (the “moat”). And on both sides of that moat we reclock using expensive ultra-low-jitter 10GHz-capable...

    Good mid-price audiophile switches

    Well it is Saturday evening and my dear wife will soon be home from a trip, so I will be brief :): I encourage people to look deeply at the actual methods being used--and what is accomplished or not--when considering various Ethernet switches and filters. And also to consider the goals. Most of...

    SFP Rolling? Anyone?

    Not unless you plan to go longer than the 10km that the FTLX1475 are rated too. ;)

    SFP Rolling? Anyone?

    Hi Bob: What I said--in response to to your excitement about those Finisars and the impression you had that AfterDark discovered them--was that I and some friends/clients/posters on several forums had been playing with and talking up quality Finisar transceivers for years, and that as with...

    Hi Chris: Alex from UpTone here. I am just now catching up on your success since our technical conversations via phone and e-mail back in April 2022, when you were just beginning to experiment and measure with the ATV boxes. Wow. Congratulations on your success! So I have a question for you...

    Network Acoustics Muon Pro Review

    We’ll phase-noise is just jitter looked at in time domain. Ultimately the reason any of any of this matters for SQ comes down to ground-plane noise induced on the master clock input pin of the DAC itself. The big transformers in the passive Network Acoustics “filters” do filter high frequency...

    Upgraded Switch and/or Fiber Optic Implementation

    Thanks gents! [I know you two are fans from over at AudiophileStyle.] And for those who have yet to hear the entirely unique (only switch in the world putting Ethernet signals over an active-differential isolation "moat" and reclocking with expensive ultra-low-jitter flip-flops) and...

    China's Economic Woes and High End Audio

    The Asian markets being a large percentage of export sales for American and European high-end manufacturers is not new. It has been that way for almost 3 decades. The last big contraction of it was back around 2008. One thing that has changed in the last 10 years has been the emergence of a...

    Who has bought esoteric wire for behind the wall

    When I built my listening studio/office nearly two decades ago I wired it with all home runs of Hovland (my old company) MainLine AC cable. It, along with the heavy duty sub-panel and all the outlets were cryogenically treated (sent to a firm with a special process—they also treated cymbal and...

    Good mid-price audiophile switches

    Sorry but I do not understand your question. The EtherREGEN has an SFP cage which accepts any SFP (small form pluggable) transceiver, be it SFP or SFP+. But that port’s only speed is Gigabit (like most all SFP transceivers), and as with other switch products it is important to match cable type...

    Good mid-price audiophile switches

    Guess you overlooked the fact that our EtherREGEN also includes an SFP for optical transceivers. So your (apparently delete) post about us not offering optical is quite incorrect. And Audiobomber is correct: John Swenson was a senior chip engineer for LSI Logic>Avago>Broadcom for 31 years...

    SOtM sNH-10G Network Switches x2 : The NEW KING of USB/Network Gadget Setup

    Blake was listing an AOC (active optical cable), which is just two SFP+ transceivers with hard-attached (not unpluggble) optical cable connecting them. SFP+ (10G) transceivers with generally work in SFP (1G) cages SO LONG AS BOTH DEVICES ARE 1G SFP. If you attach an SFP+ transceiver to a switch...

    SOtM sNH-10G Network Switches x2 : The NEW KING of USB/Network Gadget Setup

    Hi John: The Sonore opticalRendu will be back in production shortly. (1-2 months) Global chip shortages forced them (well actually my engineer partner, John Swenson, who does all the Rendu series and opticalModule design for Sonore) to revise the board using more readily available parts. As the...

    QSA - Lanedri and the Audiophile Version of the Philosophers’ Stone

    Why has nobody brought up the possibility (likelihood) that the QSA "process" is a cryogenic treatment? There are many variations of such and if done correctly it is highly audible and effective. Long ago I worked with a firm specializing in it. They offered their services and proprietary...

    Optimum Internet and Network Setup for Audio

    Hi: While there are a LOT of comments I could make, I have time for just one right now. Either remove that network switch altogether, or move it upstream of the EtherREGEN (to EtherREGEN's 'A' side) and feed your Antipodes directly from the 'B' port of the EtherREGEN. To get the most out of...

    Super3 - a supercapacitor LPS, by Farad Power Supplies

    Hi Ken: I agree with everything else you wrote, but to be clear, all the iFi Audio iPower models (including the Elite) are SMPS units. [With attendant significant leakage (that’s common-mode AC passed onto the DC cable connections), owing to the required ‘Y’ capacitor directly across the...
