The NuPrime Pure AC-4E is a high-quality AC power conditioner with four outlets that feeds your hi-fi chain with filtered, lower-noise power.
It's the more compact sibling of the Pure AC-6: same idea, four spots instead of six, flexibly split. Multi-stage filtering keeps high-frequency interference (EMI/RFI) out of the power supply – giving you a darker background against which fine detail comes through better.
Why the Pure AC-4E?
Clean power is the invisible foundation of good sound. The Pure AC-4E lowers AC noise by more than 20 dB while staying flexible: you can connect four high-power devices – or mix two high-power and two low-power outlets. That way, the power amp gets its hefty current while the DAC and streamer run especially quietly on filtered outlets.
What you get
Four Schuko outlets, sensibly split, plus NuPrime's typical care on the inside. The separated filtering feeds sensitive sources with maximum quietness, without the power amp losing any dynamics. A tidy building block that brings a whole chain onto the mains centrally and cleanly.
For anyone for whom the big AC-6 has too many outlets (or simply too much unit), the AC-4E hits the mark: the same philosophy, packed more compactly.

Who's the Pure AC-4E for?
For serious mid-sized hi-fi and high-end chains where a power amp and sensitive sources are fed together – and for anyone looking for a noticeable gain in quiet and resolution without needing six outlets right away.
Honestly: a power conditioner doesn't conjure up missing detail out of thin air – it cleans up what your mains brings in as interference. How large the effect turns out to be depends on your mains and your components. And one thing we won't hide from you: the AC-4E is the EU version with Schuko outlets – which matches the Schuko plugs that most hi-fi devices carry anyway; for Swiss T13 plugs, plan for an adapter depending on the device. We'll advise you whether and how the step is worthwhile for you.
Our verdict
The Pure AC-4E is the unassuming hero of the rack: you don't see it, you hear the result. At HD Zürisee in Wädenswil, we like it as a reasonably priced entry into separated power filtering – if you've invested in clean components, you shouldn't let the power supply become the weakest link.

Frequently asked questions
What's the difference between the Pure AC-4E and the AC-6?
The AC-4E offers four outlets, the AC-6 six. Both filter on the same principle with separate handling of high-power and source devices. The AC-4E is the more compact, cheaper solution for mid-sized chains; the AC-6 has more spots for larger systems.
Do my power amps lose dynamics through the Pure AC-4E?
No. That's exactly what the separated filtering is for: high-power devices like power amps get their hefty current, while the filters take care of the sensitive sources. That way, dynamics and quiet are preserved at the same time.
How many devices can I connect?
Four – either four high-power devices, or a mix of two high-power and two low-power outlets. That's enough for a compact chain of source, preamp, and power amp. For larger systems, the Pure AC-6 is the better fit.
Does the AC-4E fit a Swiss outlet?
The AC-4E has Schuko outlets (EU version) on the device side; it connects to the mains via a power cable. Most hi-fi devices carry Schuko plugs anyway. For devices with Swiss T13 plugs, plan for an adapter depending on the case – we'll help you assess it.
Why buy the NuPrime Pure AC-4E at HD Zürisee?
Because we advise you honestly on whether separated power filtering is worthwhile for your system – instead of just selling accessories. Andy and Maurizio help with selection and integration, service runs through our own technician. Reachable by phone, WhatsApp, or in Wädenswil.
