About the NuPrime SW Ultimate
The NuPrime SW Ultimate is a Layer 3, 12-port gigabit network switch with four shared SFP fiber ports, designed for a dedicated network audio system. It uses NuPrime's ultra-low-noise Power Engine power supply with an AC filter, a 25MHz TCXO clock with an external clock input, and a grounding terminal to keep noise out of the music data. At HiFi Boutique it ships free anywhere in the USA, with sales tax already included.
Why Choose the SW Ultimate
The SW Ultimate is built to keep power supply and clock noise away from the network that feeds your streamer or server. Its AC input passes through a filter and a high-isolation common-mode choke, and the switch runs from NuPrime's low-noise Power Engine supply.
The 25MHz TCXO clock gives a precise, low phase-noise reference for the switch, and a BNC input accepts an external 25MHz clock. Four SFP ports allow fiber optic connections, which avoid the electromagnetic interference that copper cables can carry.

FAQ
FAQ
What does an audiophile network switch do?
It passes network data to your streamer like any switch, but with a low-noise power supply, a precision clock and grounding to reduce electrical noise reaching your audio components.
How many ports does the SW Ultimate have?
Twelve gigabit RJ45 ports. Ports 9 to 12 are shared with four SFP fiber ports, so either copper or fiber is active on each.
Can I use an external clock?
Yes. A BNC input accepts a 25MHz word clock, and a switch selects the internal or external clock.
Can I connect two SW Ultimate switches?
Yes. NuPrime gives port 8 or port 9 priority for linking one SW Ultimate to another.
What warranty does the NuPrime SW Ultimate have?
NuPrime lists a 3-year manufacturer warranty for the SW Ultimate.
Does HiFi Boutique charge shipping or sales tax on the SW Ultimate?
No. The SW Ultimate ships free anywhere in the USA, and sales tax is already included, so the price you see is what you pay.
