The new JL3 Monoblocks....**are the first** amplifiers that transcend their "kind". Although their technology is "push pull triode" these amplifiers challenge all amplifiers of all design technologies.. For example the JL3s challenge single ended triodes for midrange directness and vibrancy, and they also challenge the best solid state amplifiers for bass authority and control.. Transparency, soundstaging, dynamics, purity, life - the JL3 redefines not only what a tube amplifier should be - but what any amplifier should be..
Philosophy is the most important aspect of any design, CAT's philosophy is to design their products to neither add to, nor detract from the music. They never attempt to cover up a design problem with another problem, nor do they try to introduce a supposedly complementary problem to "Synergise" with it. Two wrongs do not make a right. Only the eradication of the problem is correct.. The JL3 is CAT's statement amplifier. The culmination of sixteen years of amplifier research. Following their philosophy of design, the JL3 is not designed to sound like a tube amplifier or a solid state amplifier or any sort of cross between them.. This amplifier has been designed to allow the sound of the music to flow through, uncoloured and unencumbered by the sound of any electronic technology. The success of this design establishes a new paradigm for amplifier design amongst true music lovers everywhere. Power SupplyThe power transformers are enclosed in separate nickel plated steel housings to contain the magnetic field. CircuitryPower Triode audio circuitry produces tonal natural music by eliminating partition noise inherent in pentode designs and the resulting noise intermodulation ("grain") Low feedback (about 5dB) properly compensated design eliminates the tonal hardness of high feedback and/or improperly compensated designs whilst yielding more consistent sound quality.. Ultra-wide open loop in-circuit bandwidth of the output transformers enables operation of the amps closed loop response entirely within the open loop response, eliminating any requirement for the output stage to perform beyond its natural capability. Unprecedented stability into complex speaker loads. ChassisThe heavy steel chassis is reinforced with several welded beams for tremendous strength and elimination of low frequency vibration, yielding incredible bass solidarity. Constrained damping layer on top plate silences vibration before it can be converted into electro-mechanical noise. The output transformers are enclosed within their own magnetically solated housings which is lined with Birch plywood, one of the most musical woods, and potted in place with a combination of epoxy and elastomers for mechanical stability and control. Mechanical isolation from floor vibrations provided by high loss viscoelastic feet. ConvenienceMirror polished stainless steel maintains lustre and brilliance with minimal care. Single 10 turn master bias control per channel assures utmost sonic capability with minimum effort. Built in LCD meter. Quality Exotic low loss aerospace circuit board material. CAT wire uses ultra pure dead soft annealed copper and super low loss insulation - 7 times lower than TFE Teflon! CAT coupled capacitors reduce electromechanical noise to incredible levels. Low loss core material has 92% less hysteresis loss than grain orientated silicon steel used in all other transformer coupled amplifiers, and almost 100 times greater linearity.. Specifications:
