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

EVO 4x4 USB-C Audio Interface

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

On paper the EVO 4x4 USB-C Audio Interface takes loopback (Yes) and bus powered (Yes). It gives up ADAT expansion and TRS outputs to the Focusrite Scarlett 18i20 3rd Gen. It is the cheaper of the two, by $300.00.

Leads on

  • Loopback
    Yes
    No

    Loopback routes computer audio back into the stream without a second interface or cable.

  • Bus Powered
    Yes
    No

    Bus power means the interface runs off USB alone — no wall adapter to carry or find a socket for.

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) and preamp gain (60dB, +2dB). It gives up loopback and bus powered to the EVO 4x4 USB-C Audio Interface. That costs $300.00 more than the EVO 4x4 USB-C Audio Interface.

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.

  • Preamp Gain +2dB
    60dB
    58dB

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

  • Operating System windows, macos
  • Sample Rate 192kHz
