Innuos NET1 Audiophile Network Switch

The NET1 is the entry of Innuos's network-switch line and the chassis a STREAM1 owner reaches for when the next upgrade in the digital chain is the network feeding the streamer. A purpose-built audiophile switch with four gigabit Ethernet ports, one fiber-optic SFP port, and the kind of power supply and clock the consumer-grade switches that ordinarily live in the closet were never given.

The case is straightforward. The data a streamer pulls from the local library or the streaming service arrives at the chassis as an electrical signal carrying a packet payload and a great deal of high-frequency noise. The streamer reads the payload; what the streamer's clock and power rails do with the noise is the part the consumer-grade switch has no opinion about. The NET1 is the audio engineer's opinion about the noise. The signal is reclocked at the switch by a high-precision OCXO — the same proven oven-controlled crystal oscillator architecture Innuos developed for the previous-generation Phoenix NET — and the packet leaves the chassis with timing the downstream streamer can lock onto cleanly. The fiber-optic port lets the customer break the electrical path entirely between the network and the streamer for the cleanest possible signal isolation.

The power supply is the second half of the design. Innuos's NAZARÉ-grade engineering — the engineering brought down from the company's flagship system — is the foundation: custom-wound transformers, GaN-ARC8 rectification modules, four independently regulated and electrically isolated power rails, and a 376,000-microfarad reservoir of energy storage to deliver clean DC across the dynamic demands of the switching circuit. High-precision foil resistors set the regulation reference. The clock sees its own isolated rail. The signal sees its own. The chassis sees its own.

The build is what one would expect of Innuos at this tier. A CNC-machined aluminum chassis, 480 millimeters wide and 420 deep, weighing 28 kilograms — heavier than most amplifiers — to anchor the internals against any mechanical event the room is willing to deliver. The fascia matches the rest of the Stream Series for the customer building the front end one chassis at a time.

What the NET1 delivers in the room is the calm a network-engineered upstream is supposed to deliver. The streamer reads cleaner packets. The reclocking inside the streamer has less work to do. The noise floor of the digital front end falls in a way that is hard to attribute to any single component when the listener hears it for the first time. The NET1 is the part of the chain most customers do not think about until they hear what it does.
