The Trilogy 915R preamplifier is Trilogy’s superlative statement pre amplifier, a culmination of decades of design knowledge and a no compromise brief. The sonic character of this design being as close to the live source in performance, has been realised. Boldness and subtlety are delivered with equal aplomb.
Openness, balance and agility produced with the Trilogy 915R make music tangible, the listener is not left lacking feeling a nuance has been lost. Lithe sonic landscapes imbued with just the correct scale and perfect imaging.
The control menu is accessible through a highly intuitive rotary encoder, this facilitates all the common functions being readily available with thoughtful implementation communicated through a large red LED dot matrix display. Display brightness, customised labels and gain trims for each input, film mode, security bonding, sleep countdown, timed system switch on via TAS link, and remote operation enable you to make the 915R a bespoke experience – an interface that is a joy to use. An optional security PIN code can be entered at start up which in the event of theft would render the unit unusable.
This is a preamplifier that anticipates all the users requirements. The inputs can be named individually, and channel balance configured to suit. Dig deeper into the menu and you will find the display of valves’ work hours or temperature read of connected Trilogy amps, real-time bar graph instead of volume level, days of week and the ability to schedule on and off times to everything connected via TASlink.
The gain stage uses the 6H6P super tube mounted in a billet compartment for the voltage gain, this tube performs exceptionally well in audio applications and its associated frequencies with true high fidelity and low distortion. A series of three transformers feed the power supply, the design actively shunt regulates the valves high voltage supply. The voltage rails ability to both sink and source current allows it to be both stable and quiet. Output is provided by the renowned Lundahl transformers.
It’s apex level topology is only equalled by the attention to its casing and detailing machined from billet alloy with the attention of a purist. The philosophy of utilising the optimum technology to solve a problem is the Trilogy ethos, encapsulated in the 915R preamplifier.
The preamp is supplied as standard with the stunning billet PRC remote, and a quality ISOL-8 IsoLink Wave power cord.
The Trilogy 915R features a comprehensive range of inputs and outputs ; TASlink RJ45 socketry on the far right and a number of connections by Cardas (RCA) and Neutrik (XLR) in-between. There are six inputs (3x RCA, 3x XLR), four outputs (2x RCA, 2x XLR) and one RCA send (record) out in total. One of SE inputs can be also used as a return channel.
