Fusion of Tamura transformer and ultimate full balance configuration
Overwhelming resolution and transparency that dwells in silence
A bliss called “silence.” The pinnacle of Tamura transformers, made with Czech craftsmanship
"Boosting" in analog playback is the most delicate process that awakens the subtle musical soul engraved in the grooves of a record. The **SVPER QVATTVOR** from Czech fonolab is luxuriously equipped with four of Tamura's finest wideband transformers, a Japanese treasure that is the envy of audiophiles around the world. Completely balanced drive brings music back to life with overwhelming purity and silence.
SVPER QVATTVOR: Supreme features of uncompromising engineering
1. True Balanced Configuration
At the heart of the SVPER QVATTVOR are two sets (4 in total) of isolation transformers that have been strictly selected as matched pairs. While a typical step-up transformer processes single-ended (unbalanced) signals, this unit uses a "completely balanced transmission" that boosts both the positive and negative (+/-) signals of the MC section using independent transformers. This physically cancels common mode noise that enters the signal path, achieving an overwhelming S/N feeling and a vast sound stage that cannot be achieved with digital sound sources.

2. Adoption of Tamura's highest grade wideband transformer
Japan's treasure, Tamura's proud top lineUltra Wide Band Super Permalloy CoreWe are generously introducing transformers. Its biggest feature is its amazing frequency response of 10Hz to 120kHz. The flat characteristic that extends to the ultra-high range, which far exceeds the audible range, perfectly reproduces sharp transients, and reproduces the lingering sound of cymbals and the sound of halls.holographic soundstageIt even depicts the "signs" of the music.

3. Newly designed heavy vibration damping steel case
External vibrations and electromagnetic noise can cause fatal distortion to weak MC signals. SVPER QVATTVOR has a completely new housing design based on years of user feedback. A special damping treatment is applied to the highly rigid steel case, and each transformer is housed in an individual shielded housing to eliminate mutual interference to the utmost. This thorough "quiet design" makes the background quieter.
4. Carefully selected materials and shortest wiring (Minimal Internal Wiring)
Internal wiring is designed to be as short as possible to maintain signal freshness.
- Input terminal: A silver-plated Neutrik XLR socket is used to support the reliability of balanced transmission.
- RCA terminal: Both input and output are equipped with high-quality Teflon-insulated, gold-plated sockets that guarantee high-purity transmission. The craftsman's commitment to eliminating the causes of sound quality deterioration is condensed down to each contact point.
5. Front dematizer function improves maintainability
A transformer that becomes magnetized after long-term use can cause loss of sound resolution. This machine has a ``Demagnetizer'' button** located on the front panel that allows you to easily demagnetize the transformer. You can refresh the transformer with a single button and always enjoy listening in the best conditions without connecting any external equipment. 6. Sophisticated bespoke design by Czech Republic Product designer Jan Snegov designed an exterior with ultimate functional beauty.
- Fine satin mat: A slightly glossy finish that softly envelops light and brings out the hard beauty of metal.
- Solid Sphere Knob: An original spherical knob that fits comfortably in your hand.
- Customization: Through our in-house engineering department, we also offer "bespoke support," which allows custom-made front panel colors and finishes. It is possible to create a one-of-a-kind design that is suitable for your listening room.
Musicality: Unleashing the individuality of the cartridge
Mono & Stereo, a well-known international magazine, reviews this unit as follows.
"SVPER QVATTVOR does not merely amplify music. It makes it exist. The transparency of Tamura-made transformers and Fonolab's shielding technology elevate analog playback to an unknown dimension." The astonishing playback range from 10Hz to 120kHz and an ultra-low distortion rate below 0.05% fully bring out the wide-range performance of modern high-end cartridges, creating three-dimensional sound images from an unprecedented level of silence (S/N ratio).
In the review by 'Audio Satori,' its high versatility and musicality are highly praised.
- Denon DL-103:"Punchy, with a strong, grounded sense of energy."
- Ortofon SPU:"Dense and with an unprecedentedly clear focus in depiction." It delivers passionate performance without coloring the individuality of the cartridge. This is why SVPER QVATTVOR is considered a reference.
