Custom Built SUPRATEK CORTESE LCR phono preamplifier.
With nearly 30 years of phono pre-amplifier design and production the 2019 LCR phono preamp is the finest product to come from the famous Supratek line up of high end tube preamplifiers. Hand built in Australia from the finest components, the Cortese has evolved over many years to be among the most advanced and highest performing tube phono preamplifiers available, with performance matching , and surpassing other preamps costing ten times the price.
Designed solely for moving coil cartridges , the Cortese is possibly the quietest high gain phono stage available. While other manufacturers resort to dynamic robbing step-up transformers to achieve gain for low output MC cartridges the Cortese uses an all active tube phono design that gives maximum dynamics and quiet noise free operation. Moving coil cartridges with outputs as low as 0.1mV can be used with no need for a step up transformer , with the high levels of dynamic ease that comes from an active design.
The Cortese phono stage has always been renowned for its open and musical yet accurate sound and the LCR implementation brings higher levels of 3D imaging and soundstaging. The line-stage is of equally high calibre , with high gain , which is adjustable to suit any power amplifier, and low output impedance enabling it to drive any, or multiple power amps. It uses the famous, and perhaps the finest preamp tube ever built- the venerable 6SN7. The Supratek linestage is not a warm "tube" sounding preamp but a state of the art design that is accurate and detailed, and has a uncanny knack of bringing out the very best sound from your system and room. Its a "big/open" sound, but very controlled and realistic.
The Cortese has its own seperate power supply which is incredibly over-engineered and robust to ensure many years of reliable operation. The famous Supratek "sound" is partly derived from the tube shunt regulators , one for each channel, built into the power supply. True balanced XLR and 3x RCA outputs with 5 RCA inputs are provided or can be custom built to owners specifications. Sound quality of this calibre has previously only been available at 5 figure values and from $US5000 the Supratek LCR Cortese is the best value in true ultra hi-end hifi . Combined with stunning million dollar looks , and reliability that has been proved over many years the Cortese is a once in a lifetime purchase that will please your ears and eyes indefinitely.
Supratek takes great pride in forming long term relations with owners and there are many happy owners who have owned a Supratek preamplifier for decades , many preamps with the original tubes. They describe the Supratek preamp as the basis, and essential component of their systems.
While pleased that Supratek preamps are considered to be true classics they are also state of the art designs that will rival any preamplifier available today. Time and again they have proven to be the link that brings a system and room alive with uplifted dynamics, openness, 3D imagery and a real sense of musicality.
The Cortese LCR is available in a number of finishes. See photos. Lead times can be extended, but presently able to supply in 3-6 weeks time, depending on finish required.
