The Spartan edition is engineered for audiophiles who already know what they want —and want nothing in the way. It eliminates digital processing in favor of a clean, analog-only path, built around our celebrated tube preamp and featuring an impressive 8 RCA inputs for total system versatility.

Perfect for those who prefer using their own high-performance DACs and phonostages, Spartan gives you full flexibility over your signal chain. Customize your power module, tubes, knobs, and headphone amp —every choice tailored to your preferences.

The Billie Spartan shares the same enclosure as the Classic: compact, robust, and performance-driven. Like the Classic, Spartan is future-ready. Both the headphone module and tubes are user-upgradeable, while firmware updates install effortlessly via Mac and PC-compatible USB-C. This is an amplifier that adapts to your system, not the other way around.

USMCA compliant product –No tariffs or duty!

    | Amp Color

    Slick Silver or Bold Black? Your first choice is a simple one —both chassis share the same premium finish; only the color differs. Not sure which to pick? We suggest matching it to your existing gear or the overall vibe of your listening space.

    | Power Module

    The ICEpower 200AS2 offers a warm, organic sound with lush mids and powerful bass, delivering a harmonically rich, relaxed, and engaging musical experience.
    For those who prefer a more revealing and precise presentation, the Hypex NC252 delivers neutral transparency, lightning-fast transients, and tight bass control. Its holographic soundstage brings out fine musical details with exceptional clarity and definition. Hypex’s impressive damping factor of 340 makes it an excellent choice for speakers that are typically difficult to drive.
    Select the power module that best suits your sonic preferences.

    | DAC Module

    The Core DAC module features the ESS ES9039, offering 192kHz/24-bit resolution with DSD and Hi-Res audio support.
    The Performance DAC Module builds on this foundation with a dual ES9039 configuration, enhanced clocking, upgraded voltage regulation, and additional refinements to dynamic range and noise floor. The result is a cleaner, more spacious soundstage and a heightened sense of detail and realism—reference-level performance. For those seeking the very best from their system, it’s a compelling step forward.

    | Headphone Module

    The core Headphone Amp handles a wide range of common headphone impedances with ease, delivering ultra-low distortion and a low noise floor.
    The PERFORMANCE Headphone Amp features an entirely distinct dual-mono architecture, offering exceptional clarity and wide bandwidth to preserve dynamics. With robust output capable of driving even 600Ω loads, it’s a worthwhile upgrade for those who demand more from their headphones.

    | Tubes

    Choose between two JJ ECC99 tube options to fine-tune Billie’s sonic character. The JJ ECC99 Red, delivers a smooth, warm, and rich presentation with slightly rolled-off treble, full mids, and deep bass. It offers solid detail retrieval and soundstage width, with a more forgiving, relaxed tone.
    The JJ ECC99 Gold takes a more analytical approach—detailed, open, and dynamic, with extended treble, transparent mids, and tight bass. It presents a wider soundstage, heightened resolution, and an energetic, engaging character.

    I think you have a great sounding d class amp I’ve got it hooked up to a Metrum Acoustics ONYX Balanced NOS DAC amd Project cd transport to my Two 18 Amphion speakers with cardas wires it produces a unique sound I would say a Billie sound (I use to be a tube guy till I heard the spartan ) speechless

  2. Yutaka I. (verified owner) –

    USMassachusetts, United States

    The build quality, sound and power output of this integrated amp is comparable to much more expensive amps. I listen mostly to jazz and classical and the Billie produces tremendous warmth and depth that is very satisfying and easy to listen to for hours. The hybrid combination of tube preamp and class D amp has been implemented to perfection by Heaven 11 in the Billie.
