The optional integral phono stage makes this all the preamplifier you could ever need. The audio circuit 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.\u003c\/p\u003e\n\u003cp class=\"\"\u003eThe 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 TAS link, and remote operation are amongst the many configurable options available to personalise your 903 the way you want it.\u003c\/p\u003e\n\u003cp class=\"\"\u003eThe gain stage uses the 6H6П super tube for all voltage gain. This Russian military triode has high transconductance and low mu for exceptional performance at audio frequencies. The grounded grid configuration allows the tube to operate in pure Class A with the highest linearity and the lowest distortion. The output impedance is low for excellent drive capability.\u003c\/p\u003e\n\u003cp class=\"\"\u003eThree transformers feed the power supplies. The valve’s high voltage supply is actively shunt regulated. This topology ensures that the regulator can sink as well as source current, a vital detail that enables the voltage rail to remain quiet and stable under all conditions, a vital requirement for high resolution audio.\u003c\/p\u003e\n\u003cp class=\"\"\u003eThe optional phono stage is no marketing afterthought. It has much in common with the acclaimed 907, being a Class A design with passive RIAA EQ. The active circuit is fully discrete, the on board shunt regulators have their own power supply for maximum fidelity. Gain for either moving magnet or moving coil, cartridge resistance and capacitance loading, are all adjustable from the menu hierarchy via local or remote control via infrared handset or our powerful TAS link interface.\u003c\/p\u003e\n\u003cp class=\"\"\u003eThe 903 is of rare quality, it offers both supreme flexibility and peerless construction.

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.\u003c\/p\u003e\n\u003cp class=\"\"\u003eOpenness, balance and agility produced with this preamp 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.\u003c\/p\u003e\n\u003cp class=\"\"\u003eThe 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. \u003c\/p\u003e\n\u003cp class=\"\"\u003eThis 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.\u003c\/p\u003e\n\u003cp class=\"\"\u003eThe 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. \u003c\/p\u003e\n\u003cp class=\"\"\u003eIt’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.
