CAT

JL5 Black Path Edition

Power Supply

    • Power transformer is encased in a separate nickel plated steel housing to contain the magnetic field.

    • Isolation transformer eliminates entry of AC power line noise into the amp, yielding greater benefits than add-on conditioners without any of their sonic drawbacks or expense.

    • Slow filament power-up extends tube life greatly. Quadruple cascaded audio power supply uses time compensated zero feedback mosfets and vacuum tubes to deliver unequaled dynamic contrast, resolution and sound stage realism

Circuitry

    • Pure Triode audio circuitry produces tonally natural music by eliminating the partition noise inherent in pentode designs and the resulting noise intermodulation (”grain”).

    • Low feedback (about 7dB) properly compensated design eliminates the tonal hardness of high feedback and/or improperly compensated designs while yielding more consistent sound quality.

    • Ultra-wide open loop in-circuit bandwidth of the output transformer enables operation of the amp’s closed loop response entirely within the open loop response, eliminating any requirement to use high feedback to force the output stage to perform beyond its natural capability.

    • Massive 15lb. output transformers allow the magnetics to operate at maximum linearity while still maintaining extremely low bass capability.

    • Unprecedented stability into capacitive loads. Fantastic for driving even the most difficult electrostatic speakers.

    • Black Path Edition Features

    • Amorphous Alloy core has less than 1/12 the hysteresis of conventional grain oriented silicon steel used by the competition, yielding a level of transparency no other tube manufacturer can match.

    • Low loss aerospace circuit board material.

    • Legendary Black Gate power supply capacitors.

    • Revolutionary BLACK PATH audio capacitors.

Chassis

    • Beautiful Golden Ratio proportions.

    • Mirror polished stainless steel maintains luster and brilliance with minimal care.

    • Heavy steel chassis for tremendous strength and the elimination of low frequency vibration, yielding incredible bass solidity and rock solid imaging.

    • Constrained damping layer on top plate silences vibration before it can be converted to electromechanical noise.

    • Output transformers are enclosed within their own magnetically isolated housing which is lined with Birch plywood – one of the most musical woods.

    • Mechanical isolation from floor vibration provided by anti-resonance viscoelastic feet.

Convenience

    • No user bias adjustments. Just plug in CAT supplied tubes and play.

    • OptiBias(TM) compensates for power line fluctuations up to 10% either way. Tubes always sound their best!

    • Tube life indicator. Green indicates the tubes are still good.

    • Red indicates time to replace.

    • Tubes operated at only 1/4 rated power for very long life expectancy.
