Trilogy 906i Phono Stage

The Trilogy 907 Phono Stage remains one of Trilogy’s most loved and popular designs. Trilogy have now brought as much of the acclaimed 907’s technology as possible within the reach of a wider audience. The Trilogy 906i Phono Stage has a close bond with its illustrious sister, bringing genuine audiophile performance to a more affordable price point.

The simpler a design is; the more constraints are placed upon it. It takes real skill and experience to keep performance high and cost low. Each circuit element has been carefully assessed, developed and scrutinised by the designer Nic Poulson to ensure the highest performance possible.

The Trilogy 906i has a signal path free from cheap, off-the-shelf op-amp integrated circuits. The gain stages are single ended Class A and fully discrete. Each individual component has been chosen for its audio performance alone.

The high bandwidth and low distortion topology uses active current sources and cascode gain blocks with zero global feedback. RIAA equalisation is passive, carefully implemented with precision components. A D.C. servo eliminates the need for large value output capacitors, bringing further performance gains.

The integral low noise, linear power supply is generously specified with a custom transformer and quality branded reservoir capacitors. No generic, electrically noisy, switching wall-warts here.

The power supply rails are shunt regulated. Although the component count is higher than the inexpensive series regulator IC solution usually found here, their performance is far superior.

Settings for MM or MC gain and comprehensive cartridge loading are accessed by configuration switches on the base.

The Trilogy 906i is hand made exclusively in England. The solid, bespoke casework is finished to the same high standard as all other Trilogy products. Built to last with quality materials, beautiful durable finishes and branded components.

The Trilogy 906i may be affordable, but the 906i meets all Trilogy’s expectations. It stands as testament to Trilogy’s core company values, embracing all the qualities that make vinyl so appealing. It makes the listening experience physically, emotionally and musically involving. In other words, a pleasure.
