The Zapco Z-AP Series
With the Z-AP Series we built an amplifier to set new sound quality standards. 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). We doubled the output drivers, and increased the operating voltage of the matched final output devices. To get heat off the
output devices faster, and increase efficiency, we used a new insulator material developed for aerospace. At the differential input stage, we used 0.1% resistors to
assure the lowest possible floor. We developed our own patented, multi ground RCA connectors with extra heavy gold plating for perfect signal transfer. We even
improved the low noise gain pots had added detents to make watching levels a breeze. To top it all off, we gave it a new look, with a matt black finish and a solid
copper plate with the logo and serial number engraved right in for posterity. The Result: The ultimate SQ amplifier designed by listening with ears and much as by
measuring. So we get the possible smoothest, purest overall sound quality and, at the same time, a signal to noise ratio of over 110dB, so you get all that pure
sound quality in even the quietest of musical passages.
