he Orpheus is not just a phono preamplifier—it’s a gateway to the purest analog sound. Designed for the most discerning audiophiles, Orpheus combines timeless vacuum tube technology with cutting-edge engineering to deliver a listening experience that is both transparent and emotionally captivating. Whether you’re a vinyl enthusiast with a single turntable or a collector with multiple sources, Orpheus sets a new standard for phono preamplification.

Built-In Silver Moving Coil Step-Up Transformer

At the heart of Orpheus lies a built-in silver moving coil (MC) step-up transformer, designed to handle the most delicate signals from your cartridge. This transformer takes full advantage of its balanced differential nature, ensuring maximum signal integrity and noise rejection. For moving magnet (MM) cartridges, the signal connects directly to the input tube, preserving the natural character of your music.

Programmable Gain and Loading

Orpheus offers programmable gain and loading per input, allowing you to tailor the preamplifier to your specific cartridge and turntable setup. This flexibility ensures optimal performance, whether you’re using a high-output MC cartridge or a low-output MC cartridge.

Ground Plane Switching for Noise-Free Operation

One of Orpheus’ standout features is its ability to switch the ground plane to the active input only. This eliminates hum loops and ground noise, even in systems with multiple turntables. The result is a noise-free listening experience, allowing you to hear every detail in your music. 

Passive LCR Equalization for Purity

Orpheus uses a passive LCR equalization network between its two vacuum tube gain stages. This constant impedance filter ensures that the input stage sees a constant load at all frequencies, making its behavior predictable and free from coloration. The equalization is realized using nanocrystalline toroidal cores and monocrystalline wire, delivering a level of precision and transparency that is unmatched.

Transformer-Coupled Output for Complete Isolation

The second gain stage is loaded by a transformer, which brings the signal up to the necessary level while providing complete isolation from the rest of your system. This design ensures that the sensitive phono stage is protected from any external interference, preserving the purity of your music.

Choke Filter Power Supply for Dynamic Performance

Orpheus’ power supply features a choke filter arrangement, eliminating switching noise and other disturbances. This design keeps the voltage on the capacitor bank constant, ensuring explosive dynamics and tonal purity. The power supply is shunt-regulated and uses constant current technology for the lowest noise and best dynamic behavior.

Microprocessor Control for Precision and Convenience

Orpheus is equipped with a microprocessor-controlled operation system, ensuring precision and ease of use. The microprocessor manages the switching of relays, monitors the unit’s status, and executes incoming commands. A clean, minimalist interface keeps the focus on the music, while advanced features are accessible through a comprehensive menu system.

Solid Aluminum Chassis for Vibration-Free Performance

The Orpheus chassis is milled in-house from solid plates of aluminum of varying thicknesses, interlocked to form a ring-like structure. This design dissipates unwanted vibrations, while the circuit board is suspended on gel dampers, allowing it to “float” immune to interference. The result is a phono preamplifier that operates in complete silence, free from mechanical and electrical noise.

Experience the Orpheus Difference

The Orpheus is more than just a phono preamplifier—it’s the ultimate tool for the analog lover. Its combination of timeless tube technology, innovative engineering, and meticulous craftsmanship makes it the perfect choice for those who demand the best.

Discover the purity, precision, and passion of the Orpheus—and hear your vinyl like never before.
