Revolutionary Power Supply Architecture

The Evolution employs a completely new power supply design that sets new standards for phono stage performance. Featuring high stability regulation, an ultra-low noise floor, and passive power correction, this sophisticated power supply creates an ultra-quiet background from which music effortlessly emerges. The two-chassis configuration physically isolates the power supply from the delicate phono circuitry, ensuring that electromagnetic interference never compromises the fragile signals from your cartridge. This meticulous attention to power supply design reflects Doshi's understanding that silence is the canvas upon which music is painted.

Advanced Circuit Topology

The Evolution's circuit employs twelve valves per channel (6 x 12AX7, 12AT7, 12DW7) in a carefully optimised topology that delivers exceptional gain whilst maintaining vanishingly low noise. The MC input provides 20dB of gain (jumper adjustable to 14dB), whilst the MM section delivers 50dB, achieving a total gain of 72dB. Despite these high gain levels, the Evolution maintains a signal-to-noise ratio of at least 80dB below 1V unweighted on the MC input - a remarkable achievement for a valve-based phono stage.

Premium Component Selection

The Evolution incorporates AudioCapX and ClarityCap CMR capacitors throughout the signal path. These premium components reduce distortion whilst increasing transparency and dynamics, allowing every nuance of your vinyl playback to shine through. Combined with the premium parts employed throughout the new power supply, these carefully selected components ensure that the Evolution preserves the complete harmonic structure and spatial information encoded in your records.

Unprecedented Loading Flexibility

A truly innovative aspect of the Evolution's design is its remote-controlled loading adjustment system. Rather than requiring manual changes inside the chassis or external loading plugs, the Evolution allows you to adjust cartridge loading on the fly via the included remote control. The ability to store two MC load settings in memory enables precise optimisation for different cartridges or even different records. This revolutionary feature allows you to fine-tune the interface between cartridge and phono stage to achieve perfect synergy with your analogue front-end.

Comprehensive Connectivity

The Evolution Phono offers exceptional flexibility with three inputs total: one MC differential input (configurable with RCA or XLR connectors), one MM input at 10K single-ended, and one MM input at 47K single-ended. This configuration can be specified as either 2 MM + 1 MC or 2 MC + 1 MM to suit your cartridge collection. Two outputs can be configured with RCA, quasi-balanced XLR, or transformer-balanced XLR connections, ensuring seamless integration with any preamplifier or system configuration.

The Vinyl Connection

Drawing from Nick Doshi's professional recording background, the Evolution Phono Preamplifier understands that the basic role of any phono stage extends beyond mere RIAA equalisation and gain. It serves as the critical bridge between your turntable and preamplifier, but more importantly, it must preserve the emotional connection embedded in the grooves. The Evolution accomplishes this through its combination of innovative features, premium components, and the designer's deep understanding of how music should sound - knowledge gained from years capturing live performances at the mixing console.
