The 907 is proof that it can be all too easy to overlook what mature technologies can still offer amidst all the clamour of the digital revolution. Vinyl’s appeal as a medium of the highest quality still rightfully endures, despite today’s convenience led music market. Get ready to experience the perfect interface between your turntable and high resolution amplifier.
FROM A SOLID BILLET
The compact enclosure for the active circuitry is machined from a beautiful solid billet of ‘natural bead blasted’ anodised aluminium. Its 1.5kg mass provides outstanding physical and electrical isolation for each of the circuit elements. Even the DC from the power supply runs through its own channel within the housing, until L-C fi ltering takes place before the main power regulators.
SHUNT REGULATION & CLASS A
The commonly used series regulators, usually chosen for their lower power dissipation and simplicity, have been rejected in favour of discrete shunt regulators. These are biased heavily into Class A with plenty of voltage headroom to provide ample current for the active gain stages. The key feature of shunt regulators are not only their ability to source current but to absorb current. This gives a clear performance advantage under the dynamic operating conditions that music demands.
SEPARATE CHOKE INPUT POWER SUPPLY
The DC for the regulators is derived from a separate power supply housed in a brushed stainless steel enclosure. This can be placed remotely to keep any magnetic fields well away from the sensitive active circuitry. The custom mains transformer is designed with a low operating current density and a copper faraday screen. It feeds the main Mundorf reservoir capacitors through a bespoke inductor, forming a true choke input supply for absolute minimum electrical noise.
INDEPENDENTLY HOUSED CHANNELS
Each channel has its 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 low noise.
NO GLOBAL FEEDBACK
The circuit performance is such that global feedback is not required. RIAA equalisation is completely passive and carefully optimised with precision selected components.
The rear carries switches for MM or MC cartridges and cartridge loading. Optimum matching is easily achieved through 12 combinations of resistance and 4 of capacitance.
A THOUSAND WORDS
A picture can say a thousand words, but no image can show you just how high the quality achieved on every trilogy product is. The finish really is strikingly beautiful, sumptuous, deep and if looked after with care, will last a lifetime.
KEEPING THE MAGICAL ESSENCE OF ANALOGUE
Superbly crafted for making music at the highest level, the Trilogy 907 Phono Stage conjures up music that lives and breathes, keeping the magical essence of analogue perfectly intact... as it should be. For those who want the most from their turntable and cherished vinyl collection, the 907 is an essential purchase.
