Uptone Audio EtherREGEN

UpTone Audio is proud to announce availability of EtherREGEN. In development for nearly two years, this unique and highly advanced Ethernet switch will exceed expectations—producing surprising audible sonic improvements in fine music systems.

The goals and architecture of the EtherREGEN are completely different that any other Ethernet switch anywhere on the planet!

Other “audiophile” Ethernet switches are mostly either just clock and power supply modifications of cheap off-the-shelf switches, or passive magnetics augmented with passive filter parts and a single fancy clock board.

EtherREGEN is an all-new, from the ground-up design, built on a costly 6-layer circuit board, and its components and topology are unmatched by any other Ethernet switch.

The heart of what makes our switch so unusual is the use of ACTIVE, HIGH-SPEED, LOW-JITTER DIFFERENTIAL DIGITAL ISOLATOR chips combined with ULTRA-LOW JITTER DIFFERENTIAL RE-CLOCKING FLIP-FLOPS. No other Ethernet switch on the market attempts this (doing this, and doing it correctly is neither easy nor cheap!). On the circuit board photos you can see the isolators set across the wide “moat.”


Let’s back up a moment to explain the usage and reason for the EtherREGEN:

On what we call the ‘A’-side, there are 4 Gigabit copper Ethernet ports, plus an SFP cage for a Gigabit LC optical module. A typical user will attach a cable from their main network router or switch, and if desired any NAS (network attached storage) or other devices.

Across the “moat” at the other end of the EtherREGEN is a lone 100Mbps copper Ethernet port. We refer to this as the ‘B’-side port. It is to this port that you will attach whatever is your one computer/streamer/renderer endpoint—the component that is directly connected to your DAC (of course this includes the increasing number of DACs which themselves have an Ethernet input).

So why does this arrangement matter?

There are two types of sound-degrading influences the EtherREGEN is designed to radically decrease: Leakage—both high-impedance and low-impedance—and clock phase-noise. The clock phase-noise travels on the Ethernet signal itself and travels on power and ground planes. [Every edge coming out of any digital device caries the jitter/phase-noise of the clock used to “clock out” that edge, this shows up on the ground-plane and affects the threshold of chips’ clock inputs. This is an oversimplification of a complex subject; we intend to publish a short white paper and measurements to demonstrate this.]

The circuitry across the moat is designed to eliminate the signal-borne phase-noise from one side to the other. EtherREGEN is mostly symmetrical—there is no “dirty side” or “clean side.” While it works identically in both directions, it is best to have the DAC-attached Ethernet endpoint device (computer/streamer/etc.) alone on one side—typically the ‘B’ side.

The circuitry between ports on the ‘A’ side decreases some phase-noise effects to some degree, but not nearly as much as crossing the ‘A’>’B’ moat.

The COMBINATION of the differential isolators and the differential flip-flops is what delivers the unrivaled performance of the EtherREGEN. The differential isolators prevent the data-borne clock signature from getting onto the PCB ground-plane, while the differential flip-flops prevent the signature from getting into the flip-flop’s own internal ground network. It takes both to accomplish the great feats of the EtherREGEN.

    wow, just wow!
    I never thought that an audiophile switch would matter at all.
    Boy was I wrong.

    It get even better after hours of burn-in.
    I am using it with the UltraRendu, and the result still surprises me.

    The conversation with Joel before buying this was flawless.
    It it quite some money for a switch, and you might think it makes no difference with this switch vs a default consumer switch.
    But the difference is huge in my setup.

    After three good years feeding my DAC with a Sonore microRendu (powered by an UpTone LPS-1), which had taken my system’s sound quality into a new league, and which was further improved by the addition an UpTone Iso Regen, I have now added a combined set of upgrades that is the most dramatic improvement I’ve ever experienced:

    Adding 1) an UpTone EtherRegen ethernet switch feeding, via optical fiber, 2) a Sonore opticalRendu powered by a Farad Super3, replacing the microRendu (I’ve kept the Iso Regen in the chain).

    Joel here at Metawave was fantastic to work with — prompt, very communicative, and helpful before, during, and after the sale, volunteering a variety of useful information and working generously to get me the package of opticalRendu, Super3, and fiber and power cables and other options that would deliver the best results at a reasonable price, and in a short time frame.

    Now, after a few weeks of burn-in, the combination of the EtherRegen and the opticalRendu powered by the Super3, plus Iso Regen, has achieved, in my system at least, a stunning synergy: whole new levels of intimacy and presence, percussive detail and impact combined with supreme gentleness and removal of harshness, and almost awe-inspiring expansion of the width and depth of the soundstage into the kind of holographic immersion that I’d heard others talk about but hadn’t fully experienced before.

    I have no relationship with Joel or Meta Wave other than as a satisfied customer — I just want to thank him for helping me to take these combined steps, which can seem daunting (I was hesitating myself), but which turned out to be more worthwhile than I’d imagined. It’s a cliche but I feel it’s true: now it’s like hearing all my music again for the first time.
