The 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 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, and 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-AP Series.Class AB Competition Audiophile Amplifiers,the ultimate Zapco Sound Quality Series.
