2. Emitter II Exclusive — Elevated Power & Subtle Detail

What’s New in the Exclusive Model?
Offers more power, filtration, and sonic control. Many audiophiles report emotional reactions—from tears to awe—during listening events.

Upgraded Performance:

  • Enhanced output: 2 × 280 W @ 8 Ω, 2 × 490 W @ 4 Ω, 2 × 900 W @ 2 Ω The Audio Co.Stereophile

  • Massive filter capacitance supports seamless transient response and control.

  • Input flexibility with multiple RCA and XLR options, plus a “Direct” bypass for even purer signal paths Stereophile+1Hifihuone

Technical Highlights:

  • Uses FET op-amp input stage, MOSFET driver stage, and five MOSFET output transistors per channel.

  • Sophisticated volume control: relay-based stepped attenuation preserves purity up to a certain setting, above which gain is added Stereophile+1.

  • Unique translucent acrylic chassis reveals vibrant internal LEDs—practical and visually striking Stereophile+1.


3. Emitter II Exclusive + Battery PSU — The Final Frontier

Why Add a Battery PSU?
It isolates the input stage with pure, noise-free DC, elevating soundstage dimensionality and clarity to unprecedented levels.

Extensive Specs:

  • Total filtration exceeds 1,385,520 µF across four power sources The Audio Co.audiodrom.net.

  • Capable of delivering 1,400 W per channel into 1 Ω—extremely stable into complex loads Stereophile+1.

  • Battery pack houses six 6 V, 12 Ah batteries (~400,000 µF), delivering around 100 hours of isolated operation. Recharge and AC switchover are fully automated Stereophile.

  • Summary Comparison

    Model Key Upgrades Power Output & Filtration
    Emitter II Basic Dual PSUs, neutral dynamics 2 × 250W (8Ω), 2 × 450W (4Ω), 2 × 800W (2Ω)
