Rialto phonostage
Pure class A performance for moving magnet and moving coil cartridges.
The Rialto strips away the non-essential to focus entirely on the delicate task of vinyl amplification. Designed as the core of a high-resolution analogue chain, this compact unit prioritises sonic purity over cosmetic excess, ensuring your cartridge signal remains uncoloured and intact.
Positioned as an accessible entry into true high-end performance, the Rialto benefits from over two decades of Rothwell design heritage. It replaces complex, feature-heavy interfaces with a high-performance discrete transistor circuit that eschews global feedback, resulting in a sound that is both fast and remarkably fluid.
Sonically, the Rialto is noted for its ability to disappear within a system. It produces a spacious, organic soundstage with taut, tuneful bass and a sweet, natural treble. Rather than forcing detail, it presents a cohesive, emotionally engaging performance that remains consistent across all musical genres.
Key Features
01
Discrete class A circuitry
Eliminates crossover distortion by avoiding standard op-amps, preserving the integrity of low-level signals.
02
Minimalist signal path
Internal switching and a lack of global feedback ensure maximum transparency and channel separation.
03
Advanced power filtering
Utilises seven stages of power supply filtering to minimise noise and provide a stable foundation for the signal.
04
High-grade components
Features audiophile-grade polypropylene capacitors and 1% tolerance resistors for accuracy and stability.
Chapter 01
Design & Philosophy
The Rialto was conceived to provide genuine high-end performance without the cost associated with aesthetic flourishes. Every component and layout decision serves the singular goal of signal purity, sacrificing unnecessary adjustments or complex casework in favour of internal performance.
Chapter 02
Engineering Notes
While op-amps are often favoured for their easy specifications, they are not ideal for the ultra-low signal levels produced by moving coil cartridges. The Rialto uses dedicated discrete transistors designed to handle microvolt-level signals with greater precision, ensuring that the tail end of reverberations and subtle micro-dynamics are not lost to distortion.
Chapter 03
Sonic Signature
Reviews consistently highlight the Rialto's ability to act as a neutral conduit for music. It is recognised for a smooth, detailed, and organic character that avoids the clinical or fatiguing presentation often found in entry-level stages, making it an ideal choice for listeners who demand long-term musical engagement.
