The Z-Series Ap Of Audiophile Amplifiers - zapco Z-150.2 AP Owner's Manual

The Zapco Z-AP Series of Audiophile Amplifiers
Audiophile: An audio fanatic whose sole passion is accurate sound reproduction that
brings all the purity of a live performance to recorded music. It is a familiar term with
high-end home gear like McIntosh or Bryston, but a term always considered unattainable
in the automotive environment.
Zapco disagrees! In 1974 Zapco began a quest for perfect sonic reproduction. While
perfection may be unattainable, the quest is no less worthy. In 2000 we introduced the
C2K Competition amplifiers and by 2003 Zapco accounted for over 33% of ALL awards
at the IASCA car Audio Finals. The closest competitor accounted for only 9%. In 2012 we
introduced the new Z-Series amps with high end internal components matched for pure
sound quality. This was our first line developed by listening rather that by measuring.
That series was favorably compared to both McIntosh and Bryston home amps, and
quickly went straight to the winner's circle in Audio contests. They were called the best
Zapco ever. How did we respond?
We said "thank you, but we think we can do even better". And we did. We upgraded to
the newest audiophile caps and op-amps, redesigned the power supply, and made
board modifications to create the Z-Series LX amps. Not only did they top the car audio
comparisons, but home speaker makers even brought their speakers to our CES suite to
demonstrate what their speakers could do. The LX was beating their demo home amps
in sound quality. How did Zapco respond?
We said "thank you, but we think we can do even better". And we did! This year we built an
amplifier to set new sound quality standards for both home and car sound reproduction.
The Z-Series AP amplifiers. Home? Absolutely! In home or in car, the job of an amplifier is
the same; pure, accurate sonic reproduction. The only difference is the power supply. If
you really want to hear what your home speakers can do, get a AC~DC power supply and
a Zapco Z-Series AP amplifier. Then you'll know why your car system can sound better
than your home system.
How did we do it? We took the best of the LX amp and we tweaked the circuitry. We used
the same high-end audio quality electrolytic caps in the power supply that we used in
the LX amplifiers. In the Signal path we replaced the electrolytics with the high-end WIMA
poly caps. We used a new low noise, audio op-amp for the input stage and the smoothest
audio op-amp we could find for the signal path (the right op-amp for the right job).
