High-End Tube Phono Stage | 2 x ECC82 / 12AU7 | MM & MC Compatibility | Toroidy.pl Supreme Audio Transformer
The Fezz Audio Gaia Prestige MM/MC Tube Phono Preamplifier brings the unmistakable character of vacuum-tube amplification to the art of vinyl reproduction.
Designed for music enthusiasts who value expressive dynamics, natural tonal richness and the intimate musical experience of analogue playback, the Gaia Prestige combines two specially selected low-noise 12AU7/ECC82 vacuum tubes with a carefully engineered, stabilised power supply.
At the heart of its power supply is a Supreme Audio Grade toroidal transformer manufactured by Toroidy.pl, supporting the carefully developed tube amplification circuitry.
Compatible with suitable Moving Magnet (MM), High-Output Moving Coil (MC HO) and Moving Coil (MC) cartridges, the Gaia Prestige offers the versatility required for a wide range of high-fidelity turntable systems.
With its elegant Evolution Series design and accessible vacuum tubes, the Gaia Prestige offers both refined analogue performance and the opportunity to tailor the listening experience through compatible tube replacement.

The Musical Character of Vacuum-Tube Analogue Sound
Vinyl reproduction begins with an exceptionally delicate electrical signal generated by a phono cartridge.
To reproduce the full musical content of a record, this signal must be carefully amplified and equalised before reaching a conventional line-level input on an amplifier.
The Fezz Audio Gaia Prestige performs these functions through a dedicated vacuum-tube phono amplification circuit.
Fezz Audio describes its sonic character as warm, immersive and richly expressive, placing particular emphasis on musicality, natural timbre and the emotional qualities of analogue recordings.
The Gaia Prestige is intended for listeners seeking a combination of tube character, low-level musical detail and flexibility in cartridge matching.
Two Selected Low-Noise ECC82 / 12AU7 Vacuum Tubes
The amplification circuitry of the Gaia Prestige uses two specially selected low-noise ECC82 / 12AU7 vacuum tubes.
These dual-triode tubes form an important part of the phono amplification architecture and contribute to the distinctive design philosophy of this model.
Fezz Audio selected the 12AU7/ECC82 tube family for its analogue amplification circuit and for the possibility of tailoring sound characteristics through suitable tube alternatives.
Rather than relying on a solid-state operational amplifier, the Gaia Prestige provides a genuine vacuum-tube approach to phono preamplification.
Tube Rolling: Personalise Your Listening Experience
One of the most appealing design features of the Fezz Audio Gaia Prestige is its easily accessible vacuum-tube compartment.
A specially designed sliding window on the top cover provides access to the two 12AU7/ECC82 tubes, allowing compatible tube replacements without dismantling the main chassis.
Different compatible vacuum tubes may influence perceived tonal balance, texture and presentation, depending on the individual tube characteristics and the playback system.
This gives enthusiasts an opportunity to explore personal sound preferences while retaining the original phono stage design.
Tube replacement safety: Always switch off and unplug the unit, allow the tubes to cool completely and follow the Fezz Audio instructions. Use only compatible tube types and never access internal high-voltage circuitry.
Supreme Audio Grade Toroidal Transformer by Toroidy.pl
The quality of the power supply is especially important in phono amplification, where electrical signals are extremely small.
The Gaia Prestige incorporates a stabilised power supply with a Supreme Audio Grade toroidal transformer from Toroidy.pl.
This power supply architecture supports the operating requirements of the two vacuum tubes and the associated analogue circuitry.
Fezz Audio’s close relationship with specialist transformer engineering is reflected in this carefully designed power section.
MM, MC High Output and MC Cartridge Compatibility
The Gaia Prestige offers compatibility with appropriately matched Moving Magnet, High-Output Moving Coil and Moving Coil cartridges.
Moving Magnet (MM) Cartridges
The MM operating configuration provides a published gain of 42dB, suitable for compatible moving magnet cartridges.
It also supports suitable high-output moving coil cartridges, subject to their electrical specifications and recommended loading.
Moving Coil (MC) Cartridges
For compatible moving coil cartridges requiring greater amplification, the Gaia Prestige provides a published gain of 60dB.
Before choosing a moving coil cartridge, its output voltage, internal impedance and recommended load should be checked against the phono stage’s actual input configuration.
Chameleon Audio can assist with matching the Gaia Prestige to your turntable and phono cartridge.
Accurate RIAA Equalisation for Vinyl Playback
The Fezz Gaia Prestige uses RIAA playback equalisation to restore the intended frequency balance of conventionally recorded vinyl records.
Phono equalisation compensates for the recording characteristic applied during the vinyl mastering process.
The Gaia Prestige combines this necessary equalisation with carefully developed vacuum-tube amplification in a dedicated analogue component.
Designed for Quiet and Detailed Analogue Reproduction
Although the Gaia Prestige embraces the musical appeal of vacuum tubes, its electrical design also addresses important performance parameters such as signal-to-noise ratio, channel separation and distortion.
The published specifications include:
MM signal-to-noise ratio greater than 90dB
MC signal-to-noise ratio greater than 86dB
MM stereo crosstalk greater than 86dB
MC stereo crosstalk greater than 80dB
Total harmonic distortion below 0.2%
These figures are based on the manufacturer’s published measurement conditions. Actual playback noise also depends on cartridge output, system grounding, cable routing and surrounding electromagnetic interference.
Elegant Evolution Series Design
The Gaia Prestige combines sophisticated analogue engineering with the modern visual identity of Fezz Audio’s Evolution Series.
Its understated chassis, carefully proportioned front panel and discreet upper tube-access window allow the unit to complement both contemporary and traditional hi-fi systems.
The enclosed layout provides a clean appearance while keeping the vacuum tubes accessible through the specially designed sliding window.
Please refer to the available product variations at Chameleon Audio for currently offered colours and finishes.

Flexible Connectivity and Grounding Options
The Fezz Audio Gaia Prestige includes an RCA stereo input and an RCA stereo output for integration into a high-quality analogue playback system.
The rear panel provides practical adjustment and connection facilities, including the cartridge operating controls and a ground-loop switch.
This ground-loop control may help address unwanted hum in certain system configurations.
The Gaia Prestige also provides a grounding terminal for compatible turntables.
Recommended Connection
Turntable with compatible MM/MC cartridge → Fezz Gaia Prestige → Integrated Amplifier / Line Preamplifier
Disconnect the Gaia Prestige and amplifier from mains power before making connections.
Connect the turntable RCA signal cables to the Gaia Prestige RCA input.
Connect the turntable grounding wire to the ground terminal when required.
Connect the Gaia Prestige RCA output to a suitable AUX, CD, LINE or other line-level input on the amplifier.
Set the appropriate cartridge configuration using the rear-panel controls, following the official user manual.
Check that the mains voltage selection and fuse correspond to the local electrical supply.
Power on the equipment and adjust listening volume gradually.
Important: The Gaia Prestige output must not be connected to a second phono input. Use a conventional line-level input instead.
