Experience the Musical Expression of Vacuum-Tube Vinyl Playback
Vinyl recordings preserve musical information within the physical grooves of a record. Retrieving this delicate signal accurately requires a phono preamplifier specifically designed for the electrical characteristics of phono cartridges.
The Gratia Prestige combines appropriate signal amplification with RIAA playback equalisation, allowing a compatible turntable to become the centre of a refined analogue audio system.
Fezz Audio designed the Prestige version to deliver an expressive presentation with engaging dynamics, improved bass definition and a heightened sense of musical detail compared with its earlier Gratia design.
The result is a phono stage intended to preserve the emotional richness of recordings while revealing subtle instrumental textures and the atmosphere of a performance.
Two-Stage Amplification with Burson V5i and ECC82/12AU7 Tubes
The distinctive circuitry of the Gratia Prestige Evolution combines the Burson Supreme Sound V5i hybrid operational amplifier with two low-noise 12AU7/ECC82 vacuum tubes.
This arrangement represents Fezz Audio’s approach to combining the benefits of precision solid-state electronics with the sonic characteristics of a dedicated vacuum-tube amplification stage.
The selected ECC82/12AU7 tubes form part of the audio signal amplification circuitry and contribute to the product’s distinctive analogue character.
As with any carefully engineered phono preamplifier, final performance depends on the complete circuit, power supply implementation and appropriate cartridge matching.
Tube Rolling: Personalise the Sound
One of the Gratia Prestige’s most appealing features is its accessible vacuum-tube compartment beneath the sliding glass panel on the top cover.
This design allows owners to replace the factory-fitted ECC82/12AU7 tubes with suitable compatible alternatives in accordance with Fezz Audio’s instructions.
Different compatible tubes may produce audible differences in tonal character, texture and presentation, offering an opportunity for enthusiasts to explore their own listening preferences.
Important: Always switch off and disconnect the unit from mains power and allow the vacuum tubes to cool before replacement. Follow the manufacturer’s instructions and never open the main chassis, where dangerous voltages may remain present even after disconnection.
Supreme Audio Grade Power Transformer by Toroidy.pl
A stable, carefully designed power supply is especially important in a phono stage, where the incoming cartridge signal is extremely small.
Fezz Audio equips the Gratia Prestige with a stabilised power supply incorporating a Supreme Audio Grade toroidal transformer manufactured by Toroidy.pl.
Its power architecture supports the demanding operating conditions of the analogue amplification circuitry and reflects the manufacturer’s attention to power supply engineering.
Rather than treating the power supply as a secondary component, Fezz Audio makes it an essential part of the overall design.
Moving Magnet and Moving Coil Cartridge Compatibility
The Fezz Audio Gratia Prestige supports appropriately matched Moving Magnet (MM) and Moving Coil (MC) cartridges, making it suitable for different types of analogue playback systems.
Moving Magnet (MM) Operation
For compatible moving magnet cartridges, the published MM gain is 42dB.
This configuration is intended for cartridges with output levels appropriate to the MM amplification setting.
Moving Coil (MC) Operation
The MC operating configuration provides a published gain of 60dB, supporting compatible lower-output moving coil cartridges.
Moving coil cartridges differ significantly in electrical output and loading requirements. Cartridge specifications should therefore be reviewed carefully before choosing an operating configuration.
Chameleon Audio can help evaluate the electrical compatibility of your cartridge and turntable with the Gratia Prestige.
Rear-Panel Controls and Analogue Versatility
The Gratia Prestige Evolution provides a comprehensive selection of practical controls for vinyl playback and system integration.
Its rear panel includes dedicated MM and MC RCA input connections, an analogue output, a turntable grounding terminal, an MM/MC selector and a gain setting switch.
Additional features include a subsonic filter, Stereo/Mono selection and a ground-loop switch.
These functions provide useful flexibility for different records, cartridges and installation environments.
Subsonic Filter
Unwanted very-low-frequency energy may arise from warped records, mechanical vibration or turntable and tonearm resonance.
The integrated subsonic filter can help reduce these disturbances when appropriate for the playback system.
Stereo and Mono Modes
The Stereo/Mono switch provides an additional operating choice, particularly useful for enthusiasts who listen to appropriate monophonic vinyl recordings.
Ground-Loop Control
The ground-loop switch can help address unwanted hum in certain audio system configurations.
For optimal noise performance, appropriate signal cable routing, grounding and physical separation from sources of electromagnetic interference remain important.
Distinctive Evolution Series Design
The Gratia Prestige combines premium analogue engineering with the clean, contemporary design language of Fezz Audio’s Evolution Series.
Its substantial enclosure, understated front-panel logo and distinctive sliding glass tube-access window offer an elegant appearance that complements a wide range of high-end audio components.
With a published weight of 8kg and dimensions of 355 × 380 × 95mm, this is a substantial phono preamplifier designed for a stable position on a suitable audio rack.
Different finishes are available within the Fezz Audio range. Please refer to the current product colour options displayed at Chameleon Audio.

Connecting the Fezz Audio Gratia Prestige
The Gratia Prestige is designed to connect a compatible turntable to an amplifier or line-level preamplifier.
Recommended connection:
Turntable with compatible MM/MC cartridge → Fezz Gratia Prestige → Amplifier AUX / CD / LINE input
Switch off and disconnect the relevant equipment from mains power before making connections.
Connect the turntable’s RCA signal cables to the appropriate MM or MC input on the Gratia Prestige.
Connect the turntable grounding wire to the phono stage’s ground terminal when necessary.
Set the appropriate cartridge mode and gain according to the user manual.
Connect the Gratia Prestige RCA output to a suitable line-level input on the amplifier or line preamplifier.
Check all connections and power supply requirements before switching on.
Begin listening at a low volume and increase gradually.
Never connect the Gratia Prestige’s output to another phono input. Its equalised and amplified output should be connected to a compatible line-level input.
