Where each one actually leads

Every axis is scored out of 10 from the catalog specs below. The scores are relative to the products on this page, so a 10 means “best of these”, not “perfect”, and two identical columns mean the catalog genuinely cannot separate them. Axes the catalog holds no figure for on both sides are left off entirely rather than guessed at.

The Split

What each one wins

Focusrite Scarlett 18i20 3rd Gen

Desktop audio interface intended for creator workflows, microphone input, monitoring, and clean signal routing.

On paper the Focusrite Scarlett 18i20 3rd Gen takes ADAT expansion (Yes), TRS outputs (10, +6), headphone outputs (2, +1) and preamp gain (60dB, +5dB). It gives up bus powered to the Universal Audio Volt 276 USB-C Interface. It is the cheaper of the two, by $39.01.

Leads on

  • ADAT Expansion
    Yes
    No

    ADAT lets you add eight more inputs later instead of replacing the interface.

  • TRS Outputs +6
    10
    4

    More TRS outputs allow routing to studio monitors and outboard gear.

  • Headphone Outputs +1
    2
    1

    A second headphone output lets a guest monitor without a splitter.

  • Preamp Gain +5dB
    60dB
    55dB

    More gain drives quiet dynamic microphones like the SM7B without a separate booster.

Universal Audio Volt 276 USB-C Interface

Desktop audio interface intended for creator workflows, microphone input, monitoring, and clean signal routing.

On paper the Universal Audio Volt 276 USB-C Interface takes bus powered (Yes). It gives up ADAT expansion and TRS outputs to the Focusrite Scarlett 18i20 3rd Gen. That costs $39.01 more than the Focusrite Scarlett 18i20 3rd Gen.

Leads on

  • Bus Powered
