Aria 50i

    Pure analog. Pure musical truth

      

    The ARIA 50I is for listeners who value focus over frills—an all-analog, hand-built integrated that disappears and lets the music take center stage. With a massively quiet noise floor, iron-fisted control of bass, and the kind of dimensionality you usually expect from separates, it delivers the emotional impact of great recordings without the distraction of built-in streamers or DACs. 

    Why it matters to you

    • Hear more of your speakers. High current delivery and a damping factor over 100 translate to taut, tuneful bass and effortless dynamics at any volume. 
    • Black-background clarity. Vanishingly low distortion in every stage (down to 0.0005% in the phono section) reveals texture and space you didn’t know were in your favorite albums. 
    • Analog done right. An Alps volume control and fully discrete, complementary transistor/MOSFET output stage keep the signal path short, simple, and musical. 
    • Vinyl sounds alive. The built-in moving-magnet phono stage (40 dB gain, ruler-flat 20 Hz–20 kHz ±0.05 dB) brings out body, presence, and pace from your cartridge. 
    • Serious headphone power. A dedicated 2-watt RMS headphone section drives demanding cans with ease—perfect for late-night listening without compromise. 
    • Built to last—and serviceable. No surface-mount parts, all-discrete components, Cardas binding posts, machined (not stamped) RCAs, and Neutrik XLRs. If it ever needs attention, it’s designed to be repaired, not replaced. Handcrafted in the USA with a 5-year warranty. 


    Live with it every day

    • Connect the way you listen: 2 unbalanced RCA line inputs, 1 balanced XLR input, an MM phono input, and a home-theater/power-amp bypass for direct access to the power section. Pre-out and speaker outputs with Cardas posts included. Black or silver front panel options. 
    • Operate by feel: Front-panel controls plus remote for power, input, volume, mute, and bypass. Dimensions: 17" W × 4" H × 12.5" D. MSRP: $3,495 USD. 

    Core performance at a glance

    • Power amplifier: 80 Wpc into 8 Ω, 160 Wpc into 4 Ω; THD/IMD < 0.02%; frequency response to 100 kHz; input impedance 47.5 kΩ. 
    • Line stage: 0–250 kHz (±3 dB), THD/IMD 0.001%, >100 dB S/N. 
    • Phono stage (MM): 40 dB gain, 20 Hz–20 kHz (±0.05 dB), >80 dB S/N, 0.0005% THD/IMD. 


    The ARIA 50I contains no digital circuitry. That means no added clock noise, no firmware to age out—just a pristine, stable, timeless analog platform that partners beautifully with your preferred external DAC or streamer. 

    Every Belles ARIA 50I is hand-built in the USA using fully discrete, through-hole components—no surface-mount parts—ensuring long-term serviceability. The circuit employs a solder mask only on the component side, with solder-tinned copper traces on the solder side for robust, low-resistance connections. 


    Premium parts include machined (not stamped) RCA jacks, Cardas speaker binding posts, Neutrik XLR connectors, 1% precision resistors, and film capacitors. All signal-path wiring is pure copper or linear-crystal copper. The ARIA 50I contains no digital circuitry or oscillators (apart from the remote-control sensor); it is a purely analog integrated amplifier.
