Inverted Transconductance Coupling importantly provides a total freedom from “the sound of power supply”. Distortion is pushed below measurable limits yet the circuit is of an elegant simplicity that stands firm under dynamic conditions music signals present. \u003cbr\u003e\u003cbr\u003eExcellent coupling between source component and power amplifier, with a consummately low impedance and immense drive capability ensure the k-10 will bring out the best of the power amplifier. \u003cbr\u003e\u003cbr\u003e\u003cb\u003eInnovative design meets meticulous execution\u003c\/b\u003e\u003cbr\u003eThe K-10 pre-amplifier is crafted with meticulous attention to one purpose, musical excellence. Each element is carefully engineered to deliver the highest possible performance without compromise to concerns of cost or practicality. Form truly does follow function.\u003cbr\u003eUnnecessary complication is avoided at every turn to protect the precious music signal from adverse influences.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eSimple, finely crafted mechanical controls\u003c\/b\u003e\u003cbr\u003eThe K-10 uses the finest attenuator part available for volume control. Perfectly hand assembled in Japan, this attenuator uses exotic resistors solely created for sound reproduction. Comprising of a special carbon formulation with thick gold over oxygen free copper leads, these parts are of ultimate choice.\u003cbr\u003eSource selection is performed by a rotary switch built specifically for the most demanding of audio applications. Thus all manner of relays, complex support circuitry and sound destroying printed circuit board tracks have been eschewed entirely. \u003cbr\u003e\u003cbr\u003e\u003cb\u003eDC Reactor power supply\u003c\/b\u003e\u003cbr\u003eTo decouple the K-10’ s performance from impure AC supply lines we have adopted a heavy DC Reactor type power supply that delivers valuable advantages over other types of supply. The reactor’ s performance is further enhanced by the use of our own designed for audio, discrete zero feedback regulator to provide the amplifier with pristine DC current. \u003cbr\u003e\u003cbr\u003e\u003cb\u003eTriple screened chassis\u003c\/b\u003e\u003cbr\u003eA robust chassis creates a full copper envelope surrounding all components of the K-10 to shield them from the influences of external electromagnetic and radio frequency interference. Sensitive components within the ITC gain stage are further shielded by “double encapsulation” – a separate copper shell and a custom made mu-metal capsule within. The power supply is housed in its own “magnetic vault” made of 2mm thick soft iron plate. A sandwich floor construction with constrained layer damping and hemispherical sorbothane feet provide additional isolation from unwanted vibrations. Electrically, thermally and acoustically this lavish assembly sets an excellent operating environment for the enclosed electronics. \u003cbr\u003e\u003cbr\u003e\u003cb\u003eSingle ended and balanced output of equal performance\u003c\/b\u003e\u003cbr\u003eProviding single ended and balanced outputs of identical performance presents a challenge to pre-amplifier designers. The K-10 is successfully engineered to deliver both at full measure, affording a greater flexibility for system configuration.\u003c\/p\u003e\n\u003ch5\u003eSPECIFICATIONS\u003c\/h5\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003e27Kg unpacked.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003e169mm high with feet installed, 380mm wide and 380mm deep excluding knob and socket protrusions.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput impedance\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003e50K Ohm (Single ended)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput impedance\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003e2X37 ohm balanced, 1X 75 ohm single ended.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput equivalent noise\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003e3.5 millionths of a volt A weighted\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTypical mid-band distortion\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eLess than 0.0005% driving 10K ohm load at 4V RMS\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage gain\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003ePlus 6 dB\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency response\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eLess than 3Hz to greater than 150 KHz, minus 3dB\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower consumption\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eThirty watts.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eAVAILABILITY\u003c\/h5\u003e\n\u003cp\u003eThis item is made to order.
