High-end 8-channel ADAT preamp with serious conversion, but not cheap

Is the Focusrite Clarett+ OctoPre worth buying? Yes — if you need eight clean mic preamps, ADAT expansion, and premium conversion, it justifies its £619 price for serious recording setups. At 4.6/5 from 270 reviews, it has clearly earned trust, and the current price is the all-time lowest, which makes the timing unusually favourable for a unit that normally sits close to its £608.65 average and well below its £709.99 RRP.

What first stands out about the Clarett+ OctoPre?

The main appeal is straightforward: this is an 8-in/8-out ADAT mic preamp built for expanding a proper recording rig, not a casual desktop setup. Focusrite has aimed this squarely at musicians and engineers who want cleaner tracking, better headroom, and the flexibility to integrate outboard gear via the eight dedicated channel inserts.

The headline feature set is stronger than the usual expansion box. You get Focusrite’s all-analogue Air circuit, 118dB of dynamic range, and 129dBu EIN on the mic pres, plus improved A-D and D-A conversion. Those numbers matter because they point to a preamp stage designed to stay quiet and open when you’re tracking multiple sources at once — drum overheads, full band sessions, layered vocals, or synth-heavy productions where noise floor and clarity become obvious very quickly.

Is the sound quality worth the price?

For £619, the sound-quality proposition is the core reason to buy. The Clarett+ Mic Pre section is built around 118dB of dynamic range and 129dBu EIN, which is exactly the sort of specification that appeals to people who care about recording detail and low noise. In practical terms, that suggests a preamp that should capture quieter sources more cleanly and give you more usable gain before hiss becomes a problem.

The all-analogue Air feature is another key differentiator. Focusrite describes it as premium, relay-controlled analogue circuitry that gets closer to the origins of the classic Focusrite sound. That means this is not just a software emulation or a gimmick; it is an analogue circuit intended to change the front end character as you track. For singers, acoustic instruments, and source material that benefits from a little extra presence, that can be more useful than a purely transparent path.

The improved A-D and D-A converters are equally important because this is not only about preamp tone. If you’re using the OctoPre as part of a larger studio chain, cleaner conversion means better multitrack capture and more confident processing on playback. That matters when you are stacking multiple channels through ADAT and need the unit to behave like serious studio infrastructure rather than a convenience box.

How useful are the eight inserts and ADAT expansion?

The eight dedicated channel inserts are one of the most practical features here. They let you track through favourite outboard gear on every channel, which is a major advantage if you already own compressors, EQs, or other hardware and want to commit sound on the way in. For engineers who work that way, inserts can be more valuable than extra bells and whistles because they keep the signal path flexible without forcing you to re-patch the whole studio.

The ADAT format makes the OctoPre especially attractive as an expansion unit. It is designed to add eight channels to a compatible interface, which is a huge step up from a 2-channel or 4-channel front end. That makes it especially relevant for drummers, live session capture, rehearsal recording, or any project where you need to expand input count without replacing your main interface.

This is where the Clarett+ OctoPre separates itself from lower-cost Focusrite options like the Scarlett 8i6 3rd Gen at £269.99 or the Scarlett 2i2 Studio 3rd Gen bundle at £239.99. Those products are much cheaper and both rate 4.7/5, but they are different tools: they are complete interfaces or bundles, while the OctoPre is a higher-end expansion/preamp unit aimed at users who already have a suitable ADAT-equipped system.

Is the build quality worth the price?

The feature set suggests a unit aimed at real studio use, and the price reflects that. The presence of eight inserts, improved converters, and Focusrite’s premium analogue Air circuit all point to a product built to sit in a permanent setup rather than on a crowded desk that gets unplugged every week.

That said, the price is still high. At £619, this is not an impulse buy, and the sales rank of #6579 shows it is a specialist piece rather than a mass-market best seller. If you only need one or two inputs, or if you are not using ADAT expansion, much of what you are paying for will be unnecessary.

Is it good value for money?

Value depends entirely on your workflow. At £619, it is only slightly above the average tracked price of £608.65, and the current price is the all-time lowest, which improves the case for buying now. Against the £709.99 RRP, the 13% saving is meaningful, especially for a product that has 270 reviews and a strong 4.6/5 rating.

The value becomes clearer if you compare it to buying a cheaper interface and later needing better conversion, more channels, or outboard integration. In that scenario, the Clarett+ OctoPre can be a smarter long-term purchase than repeatedly upgrading smaller interfaces. But if your setup is still simple, the savings may be better spent elsewhere.

How does it compare to cheaper alternatives?

Compared with the Scarlett 8i6 3rd Gen at £269.99, the Clarett+ OctoPre is more than double the price, but it is not trying to do the same job. The Scarlett is a compact USB interface for recording, songwriting, and streaming; the OctoPre is an eight-channel ADAT expansion preamp with higher-end conversion and analogue Air circuitry. If you need a full interface, the Scarlett is the more economical route. If you need to expand an existing rig with better front-end quality, the OctoPre is the more serious option.

Against the Scarlett 2i2 Studio 3rd Gen bundle at £239.99, the gap is even more obvious. That bundle is for simpler recording setups and includes a condenser mic and headphones, making it far more accessible for solo creators. The Clarett+ OctoPre is for users who already have a system in place and want to raise the quality and input count.

The Yamaha HS5 at £537.83 is a different category entirely, but it is worth mentioning because it is also a high-rated studio tool at 4.7/5. If you were choosing between monitoring and input expansion, the HS5 would improve what you hear, while the OctoPre would improve what you capture. That distinction matters for budget planning.

What are the limitations?

The biggest limitation is simple: this is only worth it if your setup can use it. Without ADAT expansion and a clear need for eight channels, the Clarett+ OctoPre is overkill. Another issue is price sensitivity — even with the current lowest-ever price, £619 remains a significant outlay.

There is also a workflow warning hidden in the feature set. The eight inserts are excellent for hardware users, but if you work entirely in the box, that advantage may not matter to you. In that case, you may be paying for professional routing flexibility you will never use.

Who should buy it?

The Clarett+ OctoPre suits musicians, producers, and engineers who need eight clean preamps, ADAT expansion, and the option to integrate outboard gear on every channel. It is especially relevant for drum recording, multi-mic sessions, and home studios that are growing into more serious tracking workflows.

It is less suitable for first-time buyers, solo songwriters with one or two inputs, or anyone who just wants a simple USB interface. Those users will get better value from lower-cost Scarlett options or a monitor upgrade.

Final verdict

The Clarett+ OctoPre is worth buying for serious recording users who will use its eight channels, inserts, and higher-end conversion. At £619 — and especially at the current all-time low — it makes sense as a premium studio expansion piece, not as a general-purpose interface. If you need that exact role, it is a strong buy; if not, the price will be hard to justify.
