External power supply chassis contains the transformer’s
magnetic field eliminating it as a source of hum.
Rectification, initial regulation, and noise filtering are all
performed in the EPS thereby delivering pure quiet DC
power into the main chassis eliminating the grain and
dryness associated with noise intermodulation.
Slow filament power-up extends tube life greatly.
Quadruple cascaded audio power supply combines 22 zerofeedback
regulators with over 30 energy storage and bypass
capacitors for unequaled dynamic life, soundstage precision
Isolation transformer eliminates entry of radio frequency
noise through the AC power line yielding greater benefits
than any of the expensive add-on power line conditioners
without any of their sonic shortcomings.
Pure vacuum tube circuitry for vibrant and natural music.
Extraordinarily quiet high gain phono amp accommodates
both high and low output cartridges.
Fastest tube preamplifier, without any of the high frequency
circuit-induced edginess which slower preamps frequently
substitute for real speed. This speed is maintained even into
long runs of cable.
Lowest open loop distortion of any preamp yields unforced
detail and resolution as no other preamp can.
Low feedback ratio eliminates the aggressiveness of high
feedback designs and yet still maintains correct focus.
Matched output impedance snubs reflections on
interconnects quickly, yielding exquisitely lucid midrange
Very strong steel chassis with anti-RFI plating ensures hum
and RF free operating environment for the circuits.
Damping material lines both chassis to stop mechanical
resonances which would otherwise modulate the electric
fields in the preamp.
Mechanical isolation from floor vibrations provided by high
loss viscoelastic feet.
Exotic low loss circuit board material combines the
transparency of hard wiring with the low resonant signature
and musicality of a circuit board.
Amazing new high technology BLACK PATH capacitors used
for the critical inter-stage coupling.
Balance and volume controls are military grade rotary
switches with solid silver contacts wired with precision
CAT designed MC transformer is the flattest, fastest,
cleanest transformer ever made, regardless of price.
The best sounding precision resistors are used everywhere
for the best resolution and minimum unit to unit variability,
CAT coupling capacitors are made to our specifications and
are better than any other audiophile grade capacitor.
Premium CAT audio wire used throughout.
Rhodium/Gold jacks for superior connection.
Front panel muting switch.
Internal high/low line stage gain switch allows gain
optimization for all systems.
Automatic mute at turn on and turn off.
Record/Normal front panel taping switch
Extra set of main output jacks for A/V and special setups.
Load jack allows changing MC cartridge loading while
listening to music.
