Zapco - The ZX series

The Z-Series of Zapco amplifiers is the result of our experience over the last 40 years with the technology of sound reproduction, combined with what we have learned in consultations with the home and car audiophile communities over the last few years about human perception of sound.

We have also used a number of studies of the human physiology to examine what an amplifier should do to make reproduced music sound more like live music. What did we discover? The proper combination of output devices, op-amps, capacitors and other internal components makes a huge difference in the quality of the sound an amplifier produces.

The ZX-Series Class D line-up takes the Z-Series to a whole new place of Crazy Power!
6,500 watts, 10,000 watts, or 24,000 watts. Now that's Crazy Power!
Like we say, these are the amps to use "when too much is just not quite enough".

We also determined that with technological advances over the last 10 years we could now develop a more efficient Class D amplifier that would have the SQ specs at 1Ù to equal or even surpass those of most A/B amps.

What we did: We set our standards for specifications in Class A/B and Class D and assured that all amps would meet them.

Then we used the best combination of tantalum capacitors, electrolytic capacitors, NJM 5532 and OPA 2134 op-amps, and Sanken and KEC high speed bi-polar output devices, and MOSFET output devices for the Class D amplifiers, to produce what we believe are the best sounding amplifiers we have ever offered.
