Trilogy 906 MM & MC Phono Stage
Vinyl’s timeless musical appeal is very close to the heart of Trilogy. The 907 Phono Stage remains one of our most loved and popular designs. We have now brought as much of the acclaimed 907’s technology as possible within the reach of a wider audience. The Trilogy 906 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 component has been chosen with care, each circuit element carefully assessed, developed and scrutinised by the designer Nic Poulson to ensure the highest performance possible.
The 906 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 DC servo eliminates the need for large value output capacitors, bringing further performance gains.
Settings for MM or MC gain and loading are accessed by configuration switches on the base.
For cartridge loading there are six values of resistance from 70 Ohms to 47K Ohms and four values of capacitance from 100 to 420 picofarads available, accommodating a very wide range of cartridges.
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. They can sink as well as source current to the active circuits. This crucial difference gives them superior transient response, making them ideally suited to the dynamically demanding conditions of high performance audio.
The 906 is hand made exclusively in England. The solid, bespoke casework is finished to the same high standard as all other Trilogy products. We use quality materials, beautiful durable finishes and branded components, built to last.
