Trilogy 975
Phono Stage
The 975 with external power supply, is our ultimate reference phono stage. The main unit is a housed in a massive machined billet weighing more than 5kg providing outstanding physical as well as electrical isolation for each of the circuit elements.
Each channel has an independently housed and isolated gain stage. The fully discrete topology is single ended; achieving high bandwidth and low distortion through the use of active current sources and cascode gain blocks. Precision matched input transistor pairs ensure ultra low noise. Gain settings for MM or MC and a wide array of cartridge loading are easily achieved via configuration switches underneath.
The common series regulator, usually chosen for its lower power dissipation and simplicity, has been rejected in favour of discrete shunt regulators biased heavily into Class A for plenty of headroom. The key feature of shunt regulators is their ability to sink, as well as source current. This gives a clear performance advantage under the dynamic operating conditions that music demands.
The DC for the regulators is derived from a remote power supply. A meticulously designed external PSU feeds the main unit with clean optimum current.
The enclosure can be placed to keep any magnetic fields well away from the sensitive active circuitry. The custom mains transformer is a low current density design with a copper Faraday screen. It feeds the main custom reservoir capacitors via a bespoke inductor, forming a true choke input supply for absolute minimum electrical noise.
Superbly crafted for making music at the highest level, the Trilogy 975 sets a new benchmark, conjuring music that lives and breathes, keeping the magical essence of analogue perfectly intact.
Trilogy 906i
Phono Stage
The 907 Phono Stage was 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 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 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 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 906i may be affordable, but the 906i meets all Trilogy's expectations. It stands as testament to our 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.
