At a Glance
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
Audient EVO 4
Compact 2-in/2-out USB-C interface with Smartgain and clean preamps for creators and podcasters.
On paper the Audient EVO 4 takes loopback (Yes) and dynamic range (113dB, +2.5dB). It gives up sample rate and headphone outputs to the SSL 2+ USB Audio Interface. It is the cheaper of the two, by $70.00.
Leads on
-
LoopbackYesNo
Loopback routes computer audio back into the stream without a second interface or cable.
-
Dynamic Range +2.5dB113dB110.5dB
Wider converter dynamic range means less noise between the quietest and loudest parts of a take.
SSL 2+ USB Audio Interface
Desktop audio interface intended for creator workflows, microphone input, monitoring, and clean signal routing.
On paper the SSL 2+ USB Audio Interface takes sample rate (192kHz, +96kHz), headphone outputs (2, +1), TRS outputs (4, +2) and preamp gain (62dB, +4dB). It gives up loopback and dynamic range to the Audient EVO 4. That costs $70.00 more than the Audient EVO 4.
Leads on
-
Sample Rate +96kHz192kHz96kHz
Higher sample rates capture more audio detail — important for professional recording and mixing.
-
Headphone Outputs +121
A second headphone output lets a guest monitor without a splitter.
-
TRS Outputs +242
More TRS outputs allow routing to studio monitors and outboard gear.
-
Preamp Gain +4dB62dB58dB
More gain drives quiet dynamic microphones like the SM7B without a separate booster.
