The Opera Audio Consonance Reference R40 tube phono preamplifier masterfully combines the advantages of a high-end tube circuit with an optimized phono stage for MC cartridges, delivering an extraordinary listening experience. Its external power supply, featuring tube rectification and protected against EMI and RFI interference, ensures a clean and stable signal. Particularly refined is the handcrafted MC step-up transformer with an amorphous core, offering an extremely wide frequency range; the hand-wound coils and point-to-point soldering reflect a design focused on achieving the lowest possible noise floor.

The RIAA equalization section is designed using a passive topology, eliminating any potential interference from radio frequencies or electromagnetic fields, and ensuring a sound free of unwanted noise. The internal wiring, also carefully handcrafted, further enhances signal quality.

Thanks to its warm, rich tonal character, wide frequency extension, and powerful dynamics, the Reference R40 stands out as a true benchmark in the world of tube HiFi for vinyl. Every musical detail is brought to life, offering an engaging and immersive listening experience that meets the expectations of even the most demanding audiophiles. For those seeking a phono preamp that blends refined craftsmanship, signal purity, and outstanding performance, the Opera Audio Consonance Reference R40 is an essential choice.
