無帰還 · No Feedback

One curve.
Uniform past 100kHz.

The Soulnote E1 Phono Stage is a perfectly balanced, non-NFB phono equalizer that keeps RIAA accurate well beyond where most designs give up.

Nothing in the way

mu — nothing added

Everyone adds.
Soulnote subtracts.

The best producers know the secret: the art is what you leave out. Soulnote engineers the same way — every stage a conventional design adds to the signal path is a chance to blur the original waveform, so Soulnote removes them, one by one, and tunes what remains by ear.

Between input and output: 3 extra stages, each with a fingerprint. Between input and output: almost nothing.

Every stage does a job — and leaves a fingerprint on the waveform as it passes through.

Fewer hands on the signal. What remains was chosen by listening — part by part.

Does the E1 take both MC and MM cartridges?
Yes. A balanced XLR input for moving-coil, an MM input that also suits step-up transformers, and a six-position load selector from 1,000 ohms down to 3 ohms.
What is different about the RIAA equalization?
The RIAA elements sit in the voltage-amplifier loads, so the curve is uniform to beyond 100 kHz without a feedback loop or a passive CR network in the path. Transients stay fast and the top end stays natural.
What does the LOW CUT switch do?
It filters the subsonic movement a warped record produces, so your woofers stop pumping and the amplifier stops wasting current on it.
About the Soulnote E1 Phono Stage

Non-NFB Vinyl, From Input to Output: Soulnote E1 Phono Stage

The Soulnote E1 Phono Stage brings Soulnote's completely non-NFB philosophy to the delicate art of vinyl replay — a perfectly balanced, discrete phono equalizer designed to unlock the sonic realism and clarity buried in your records. Built by ex-Marantz engineer Norinaga Nakazawa's team, it delivers the transient speed and extended, natural high frequencies that only a non-NFB amplifier can.

RIAA the Soulnote Way

Rather than conventional CR or NF equalization, the E1 incorporates the RIAA elements into the voltage-amplification circuit loads, ensuring uniform quality across the entire frequency range — remarkably, right up beyond 100 kHz. The result eliminates the drawbacks of both traditional approaches, for perfect curve characteristics and a striking gain in clarity and realism.

Balanced, Flexible, Built for Any Cartridge

The E1 fully supports balanced moving-coil input via XLR terminals — becoming a truly balanced, non-NFB phono equalizer from input to output — while an MM input handles moving-magnet cartridges and MC step-up transformers. A six-position LOAD selector (1,000 / 300 / 100 / 30 / 10 / 3 ohms) dials in the perfect match for your cartridge, and a LOW CUT switch tames woofer pumping from warped records. A fully balanced non-NFB buffer drives the strong, balanced output.

Frequently Asked Questions

Does the E1 support both MC and MM cartridges?

Yes — it has a balanced XLR moving-coil input plus an MM input (which also suits MC step-up transformers), with a six-position load selector to match your cartridge.

What does the non-NFB design do for vinyl?

By building the RIAA equalization into the voltage-amplifier loads rather than a feedback loop, the E1 achieves uniform response beyond 100 kHz with the fast, natural transient response non-NFB circuits are prized for.

What load settings are available?

Six MC load impedances: 1,000, 300, 100, 30, 10 and 3 ohms.
