Canor Asterion V3 Tube Phono Preamplifier, Performance Line
The Asterion V3 is a tube-based phono preamplifier with both XLR and RCA inputs and support of both MC and MM cartridges
Highlights
01 Designed for MM and MC cartridges with high variability of resistance and capacitance settings.
02 Supports balanced and unbalanced MC cartridge connections.
03Carefully selected and matched tubes with exceptional parameters.
Purist architecture without global feedback
The Asterion V3 analog stages are designed without the use of global feedback, ensuring the natural dynamics and tonal purity of the signal are preserved. This solution eliminates unwanted phase distortions and preserves the integrity of the recording in its authentic form. The result is a vivid and detailed sound image with precise spatial rendering.
Four-stage tube preamplifier chain
The amplifier chain uses four stages equipped with ECC83S and ECC81 tubes to achieve high gain with low noise. Between the first two stages is an integrated subsonic filter, which effectively eliminates unwanted low-frequency interference without affecting the audible band. This combination ensures a stable, linear signal and high fidelity reproduction.
Phono settings adjustable via remote control
The versatile remote control allows you to control all key preamplifier functions directly from the listening position. In addition to choosing between MM and MC cartridges, it can also precisely adjust the impedance and capacitance values according to the specifications of your cartridge.
Intuitive experience and perfect readability
The best of both worlds thanks to the combination of touch and matrix display. While the touch interface ensures seamless interaction with the device, the matrix display guarantees perfect readability of all key information from any distance.
Multi-level shielding of the mains transformer
The power supply uses a transformer with primary and secondary windings separated by copper foil, which effectively blocks the penetration of network interference. The entire component is cast in anti-vibration compound and enclosed in a 4 mm thick steel housing, which ensures perfect electromagnetic shielding and prevention of mechanical hum.
Five-stage anode voltage filtration
To deliver maximum stability and clean power, the Asterion V3 features a high-precision, five-stage anode voltage filtration system. This multi-stage process rigorously eliminates residual ripple and mains interference, ensuring it won't degrade the delicate audio signal.
CMT ™ technology
The Asterion V3 utilizes our advanced CMT ™ technology (CANOR ® PCB Milling Technology) for optimal performance. The CMT™ technology allows us to get the dielectric loss factors (loss tangent) of PCB close to the loss factor of air. Thanks to this technology, we managed to repeatedly reach the parameter level of the so-called “wire-to-wire connections“.
Product features
- The Asterion V3 offers exceptional gain control and precise input impedance and capacitance selection for all types of cartridges. This flexibility allows for optimal parameter adjustment, thereby achieving the maximum sonic potential of any turntable system.
- A top-of-the-line Lundahl step-up transformer is used for the MC inputs, ensuring natural signal amplification with minimal noise.
- The RIIA correction curve is made up exclusively of passive corrections containing high-quality polystyrene and polypropylene capacitors.
- The device supports the simultaneous connection of two cartridges—one MM and one MC—allowing you to switch between them seamlessly.
- The versatile remote control allows you to control all key preamplifier functions directly from the listening position.
- The touch screen integrated in the control panel allows easy and intuitive access to all device functions and settings.
- The massive control knob uses a pair of precision bearings for smooth operation.
- The device combines high-quality materials, aluminum and steel.
