Focusrite: The People's Choice
Focusrite's Scarlett series has become a fixture of home recording, with extensive software bundles and an installed base large enough to make it the default recommendation in many beginner threads. The 3rd-generation Scarlett 2i2 introduced new "Air" preamp emulation, USB-C, and improved converters; MusicTech's review of the 3rd-gen lineup called the changes a meaningful step up over the 2nd-gen across the range (MusicTech, "Focusrite Scarlett 3rd Gen review"). Sound on Sound's coverage of the subsequent 4th-gen Scarlett family documents further refinement of preamps and metering (Sound on Sound, "Focusrite Scarlett 4th Gen").
Focusrite Strengths:
- Wide Adoption: Among the most commonly recommended starter interfaces in beginner-recording communities
- Software Integration: Bundled with Ableton Live Lite, Pro Tools Artist (time-limited), and a Focusrite plug-in collection per the manufacturer's spec page
- Approachable Controls: Front-panel layout that MusicTech's review describes as straightforward for first-time users (source)
- Long Product History: Multiple generations of iterative refinement
- Range Coverage: Solo through 18i20 / OctoPre formats
What the Scarlett Range Is Less Suited For:
- Sonic "Character": In MusicTech's editorial framing, the Scarlett aims for clean, neutral capture rather than a distinctive coloration (source) — readers wanting console-style warmth may prefer the Audient line below
- Chassis Material: The entry models use a plastic enclosure per Focusrite's own spec page; the larger Clarett+ and OctoPre units are metal-bodied
- Feature Conservatism: Editorially, Focusrite's iteration cadence trails MOTU's on networking and DSP features
- Perception in Pro Circles: Long-running Gearspace discussion threads on starter interfaces frequently cast Scarletts as "first interface" rather than "destination" gear — a community-sentiment observation, not a defect claim
Audient: The Analog Purist
Audient applies its mixing-console heritage to compact USB interfaces. Sound on Sound's review of the iD4 and iD14 MkII calls the sound quality "exemplary" with "flawless" performance and "solid build quality" (Sound on Sound, "Audient iD4 & iD14 MkII"). MusicTech's MkII review notes the AD/DA dynamic range improved by +5dB and +9dB respectively versus the original iD14, with bus-powered operation and to-spec phantom power (MusicTech, "Audient iD4 & iD14 MKII review"). Tape Op's iD14 MkII review reaches a similarly favorable conclusion on preamp quality and build (Tape Op, "Audient iD14 mkII").
Audient Strengths:
- Console-Lineage Preamps: Audient markets the iD-series mic pres as derived from its ASP8024 console; Sound on Sound's review supports the sonic impression (source)
- All-Metal Chassis: Sound on Sound notes the all-metal construction with "decent heft" across the iD MkII line (source)
- Smartgain & ScrollControl: MusicTech's review highlights ScrollControl as "natural, tactile" software control without MIDI-learn setup (source); Sound on Sound's EVO review separately praises the EVO line's auto-gain "Smartgain" feature as "quite brilliant" (Sound on Sound, "Audient EVO 4 & EVO 8")
- Reputation in Pro Audio: Audient is widely covered in Tier-1 pro-audio outlets (Sound on Sound, MusicTech, Tape Op)
What the Audient Range Is Less Suited For:
- Software Bundle Scope: Audient's included-software offering is more focused than Focusrite's larger DAW + plug-in pack — relevant for buyers who want everything in one box
- Per-Channel Pricing: Manufacturer-stated pricing for equivalent channel counts tends to sit above the Scarlett line
- Catalog Breadth: Fewer SKUs across the range than Focusrite
- Networked / DSP Features: The iD line is intentionally simpler than MOTU's mixer/DSP offering — by design, not by deficiency
MOTU: The Technical Innovator
MOTU's M-series and 828 lines emphasize specifications, on-board DSP routing, and (on the larger units) digital expansion. Sound on Sound reports the M6 uses ESS Sabre32 Ultra DACs to reach an A-weighted dynamic range of 120dB at the main outputs, with a manufacturer-stated EIN of -129 dBu and a round-trip latency of 2.5ms (Sound on Sound, "MOTU release M6 audio interface"). For the larger 828 line, Sound on Sound's review of the 828es calls it "the best-sounding 828 yet" and the most expandable thanks to AVB networking (Sound on Sound, "MOTU 828es").
MOTU Strengths:
- Measured Conversion Performance: Sound on Sound documents the M6's 120dB A-weighted dynamic range and 2.5ms round-trip latency figures (source)
- On-Board DSP Mixer: The CueMix / on-board mixer architecture is documented in Sound on Sound's 828es review (source)
- Digital I/O & Networking: ADAT, S/PDIF, and AVB on the 828es expand channel counts well past USB-only competitors
- Multi-Interface Scaling: Useful for studios building toward larger track counts
What the MOTU Range Is Less Suited For:
- Configuration Surface Area: Sound on Sound's 828es review notes that long-time 828 owners will need to "forget what they knew about CueMix" and learn a more complex new UI from scratch (source) — read that as a learning-curve trade-off, not a defect
- Beginner Friendliness: The M-series is straightforward, but the 828-class units offer more features than a first-time recordist needs
- Software Bundle: Smaller plug-in collection than Focusrite's pack, per manufacturer spec pages
- Entry Pricing: Manufacturer-stated MSRP for the M6 sits at $399.95 per Sound on Sound's announcement (source) — above the cheapest Scarlett tier
Performance Deep Dive
Preamp Quality
Focusrite (Scarlett 2i2): Reviewers describe the 3rd-gen Scarlett preamps as clean and transparent with the optional "Air" mode adding high-end emulation; MusicTech's review found the changes a clear step up over the 2nd-gen at the same price tier (MusicTech).
Audient (iD14 MKII): Sound on Sound describes the sound quality as "exemplary" and the build as solid; MusicTech notes the MkII improved AD dynamic range by +5dB and DA by +9dB versus the original iD14 (Sound on Sound; MusicTech).
MOTU (M6): Per Sound on Sound, MOTU specifies an EIN of -129 dBu and the M6's main-out dynamic range is 120dB A-weighted thanks to ESS Sabre32 Ultra DACs (Sound on Sound) — manufacturer-stated figures cited by SOS.
Build Quality and Design
Focusrite (Scarlett OctoPre): Sound on Sound's review of the Scarlett OctoPre Dynamic recommends it for the per-channel price, calling out two-way ADAT and on-board analog compressors as standouts (Sound on Sound, "Focusrite Scarlett OctoPre Dynamic").
Audient (EVO 4 / EVO 8): Sound on Sound's EVO 4 / EVO 8 review found recording quality "excellent," latency "excellent" down to "a couple of milliseconds" at small buffer sizes, and could not distinguish the EVO from the MOTU M4 in A/B (Sound on Sound).
MOTU (828es): Sound on Sound calls the 828es the "best-sounding 828 yet" and the most expandable, citing AVB networking (source).
Software and Ecosystem
Focusrite: Bundled DAW (Ableton Live Lite, time-limited Pro Tools Artist) plus the Focusrite plug-in collection per manufacturer spec pages.
Audient: A more focused bundle (Cubase LE, plus Audient's ARC plug-in pack) per Audient's spec pages.
MOTU: Performer Lite, Ableton Live Lite, and "over 100 virtual instruments" with "6GB of loops and sample packs" per Sound on Sound's announcement coverage (source).
Value Proposition Analysis
Entry Level ($100-300)
Focusrite covers this tier most broadly with the Solo and 2i2. Audient's iD4 MkII competes on build and preamp quality. MOTU's M2/M4 sit here as well — Sound on Sound's EVO review notes the EVO 4 was indistinguishable from the MOTU M4 in A/B (source).
Mid-Range ($300-800)
The MOTU M6 lands here at $399.95 manufacturer-stated MSRP (SOS). The Audient iD14 MkII and Focusrite Scarlett 4i4 are direct alternatives.
Professional ($800+)
The MOTU 828es and Focusrite Clarett+ OctoPre live in this tier — the latter reviewed favorably by Sound on Sound (Sound on Sound, "Focusrite Clarett+ Octopre").
Use Case Recommendations
Choose Focusrite If:
- You want the broadest software bundle for a starter interface
- You value the largest installed base / community support
- You prefer clean, neutral capture over preamp coloration
- You're spec-shopping the entry tier
Choose Audient If:
- You prioritize preamp character and metal-bodied build (per Sound on Sound's iD MkII review)
- You value Smartgain / ScrollControl features (per MusicTech)
- You want recording quality flagged as "exemplary" by SOS
- Software bundle scope is secondary
Choose MOTU If:
- You need on-board DSP routing or digital expansion (ADAT/AVB)
- Manufacturer-stated dynamic-range and EIN figures matter to your decision
- You're scaling toward higher channel counts
- You can absorb the configuration learning curve SOS notes on the 828es
The Verdict: Match Your Priorities
Each brand reflects a different design philosophy. Focusrite optimizes for accessibility and bundle value. Audient optimizes for preamp character and build. MOTU optimizes for technical specs and routing. None of the three is "wrong" — Tier-1 reviewers cited above publish favorable findings on all three lines, and the right pick depends on which trade-offs match your workflow.
