The Last Meter Is Distorting Your Sound Your streamer is only as clean as the network feeding it. You've invested in a serious DAC, a quality streamer, and good cabling throughout. But if your audio gear is sharing a copper network with your NAS, router, televisions, and smart home devices, every one of those connections is a noise source — and that noise arrives at your streamer as electrical interference riding the ethernet cable. The result is a subtle but persistent haze: softened transients, compressed imaging, a slight flatness to dynamic peaks that you might have been blaming on your DAC, your amp, or your room. The culprit is almost always upstream. Why We Chose the Lumin N1 We stock Lumin because they build things the right way — no shortcuts, no compromises, no bloat. The N1 is the first dedicated network switch we've seen from Lumin, and it answers the question we've been asked for years: how do you clean up a complex multi-source system without building a bespoke IT rack? The answer is ten ports of carefully engineered isolation, an internal linear power supply, and an external clock input that ties the whole system to a single timing reference. This is the switch Lumin built for people who refuse to compromise on any part of the signal chain. What the Specs Won't Tell You Four Fibre Ports Changes Everything About System FlexibilityMost audiophile switches give you one fibre SFP port — useful, but limiting. The N1's four fibre ports mean your Lumin streamer, a second source, a NAS, and a dedicated audio zone can all connect via optical simultaneously. Total galvanic isolation isn't a feature you toggle — it's the default for everything that matters most in your system. Copper is there for the gear that doesn't need it. Linear Power Done ProperlySwitching power supplies are cheap to manufacture and they pollute your network. The N1 runs on an internal linear supply with an oversized toroidal transformer — the same philosophy Lumin uses in their flagship streamers. The switch itself never becomes a noise source. The foundation is quiet before a single packet is sent. A Clock Input That Ties the Whole System TogetherThe 10M external clock input is a detail that separates the N1 from every generic audiophile switch on the market. If you own a Lumin U2X — which has 10M clock outputs — your streamer and your network switch can share a single timing reference. The result is a reduction in timing jitter across the entire digital chain, not just at one component. It's the kind of system-level thinking that takes years to develop. The Audio Two Verdict We've seen the audiophile network switch category grow rapidly over the last few years, but most products in it are modest re-housings of generic IT hardware with a linear power supply bolted on. The Lumin N1 is not that. Four fibre ports, a clock input, ten total connections, and Lumin's proven CNC machined aluminum chassis — this is purpose-built for serious systems. If you're running a Lumin U2X, X1, or P-series player and you've already addressed your analogue chain, the N1 is the most logical next step. It removes a noise source you may not even know is there. That's exactly the kind of upgrade that makes music sound more real without changing anything you can point to. Tech You Can Hear What You Hear Why It Happens Sharper, more defined transients Electrical noise on copper ethernet smears timing — optical isolation removes it entirely Wider, more stable stereo image Ground-loop interference collapses imaging; galvanic isolation eliminates the shared ground path Blacker background between notes Linear power supply generates no switching noise; the network itself becomes silent More precise timing on complex passages 10M clock input synchronises the switch with the U2X or a master clock for reduced jitter Consistent performance across all connected sources All critical equipment connects via fibre SFP — isolation isn't selective, it's system-wide Same sonic benefits in any room or system layout Zero configuration required — isolation is built into the hardware, not configured in software Technical Highlights 10 total ports: 6x Gigabit RJ45 copper + 4x SFP fibre optical 10M external clock input for synchronisation with Lumin U2X or a master clock Internal linear power supply with extra-large toroidal transformer Zero configuration required — plug and play CNC aluminium chassis based on Lumin D3/U2 Mini architecture Available in anodised black or raw silver finish Why Choose Audio Two A purchase at this level deserves more than a product page.
