US
£432.88 16 inputs, 16 outputs up to 96 kHz 24-bit near zero hardware monitoring (low latency ASIO) 8

The AudioFire Pre8 is a 1U FireWire audio/MIDI interface with eight high-quality mic preamps, 8 analog ins/outs plus ADAT and S/PDIF digital I/O, and dual FireWire ports. It supports 24-bit/96 kHz operation, word clock, MIDI, and near-zero hardware monitoring, suited for project and professional studios needing extensive I/O and clean preamps.

★ Ideal for

It suits the question 'quietest Firewire audio interface available' because it lists low noise preamps (-130 dBu EIN) and near-zero latency monitoring, providing excellent low-noise performance.

Focusrite Saffire Pro 40 (Scarlett era predecessor, FireWire)
US
£373.07 20 in, 20 out 96 kHz 24-bit 8

The Saffire Pro 40 is a 20-in/20-out FireWire audio interface with eight Focusrite mic preamps, ADAT/SPDIF I/O, two headphone outputs and a zero-latency DSP mixer. It offers 24-bit/96kHz conversion, JetPLL jitter elimination and extensive routing suited to project and small professional studios.

★ Ideal for

Ideal for the question because its low-noise eight Focusrite preamps and 24-bit/96kHz conversion make it well-suited where quiet, high-quality FireWire audio capture is required.

MOTU 828mk3 Hybrid (FireWire and USB)
US
28 inputs / 30 outputs 192 kHz (analog) / 96 kHz (digital ADAT/S/PDIF) 24-bit 2 mic/guitar preamps

Hybrid FireWire/USB2 audio interface with on-board DSP mixer (CueMix FX), 28 inputs and 30 outputs, ADAT and S/PDIF digital I/O, and two front-panel combo mic/guitar inputs with hardware limiters. Suited for studios and live rigs that need expandable I/O, standalone mixing with effects, and high-resolution analog recording up to 192 kHz.

★ Ideal for

Best for users seeking the quietest FireWire interface because it offers high-resolution 24-bit analog recording at up to 192 kHz and precision digitally controlled analog trim with clip protection, minimizing noise and distortion.

MOTU 896mk3 Hybrid (FireWire)
US
28 Input / 32 Output 44.1 / 48 / 88.2 / 96 / 176.4 / 192 kHz 24-Bit 8

Hybrid FireWire/USB2 audio interface with eight combo mic/instrument preamps, 28 inputs and 32 outputs, onboard DSP-driven CueMix FX (reverb, EQ, compression) and up to 24-bit/192 kHz operation. It includes extensive digital I/O (ADAT, AES/EBU, S/PDIF), front-panel metering, standalone mixer operation and word clock I/O, suited for studio and live use. Ideal for users who need lots of I/O and onboard mixing/effects without computer processing.

★ Ideal for

Suitable for the question because it offers very low-latency onboard DSP monitoring (CueMix FX) and 8 high-quality preamps with 24-bit/192 kHz converters, minimizing noise and host-latency for quiet FireWire recording setups.
