Trilogy 914 Fully Balanced Preamplifier

The audio circuit of the 914 preamplifier benefits from Nic Poulson’s years of experience in audio design, his pursuit of transparency and true fidelity leads to an elegant solution that reflects the passion of the designer.

A truly versatile fully balanced pre amplifier from input to output. Six inputs, three of them balanced, and three RCA are provided. There is one balanced and one RCA output per channel. Signal switching in the 914 is handled by no less than 28 sputtered ruthenium Pickering relays.

Once again, using our favourite high transconductance 6H6П super tube to articulately voice all gain duties. Six in all feature in this products circuit. Three separate transformers one for ancillary control electronics, one for the valve’s heaters and one for the high tension supplies minimise interaction and maximise musical return.

The importance of shunt regulated power supplies cannot be overstated and ensures the voltage rail remains silent, since the regulator can sink and source current as dictated by the audio circuit. The 914 boasts no fewer than four such supplies.

Once again the convenience of Trilogy firmware makes the 914 a joy to use, and encourages the owner to dig deeper into the settings. The control menu is accessed intuitively using the rotary encoder plus enter and escape buttons. The hierarchy is carefully designed to put all the commonly needed commands close to hand. Display brightness, customised labels and gain trims for each input, film mode, security bonding, sleep countdown, timed system switch on via TASlink, and remote operation are amongst the many configurable options available to make the 914 truly yours.

The 914 is of rare quality, it offers both supreme flexibility and peerless construction. Above all, it is the sublime musical performance that will convince you of its rightful place; at the very heart of your system.
