ST-B Series

ST-B Series — clean, capable amplification built on the Zapco foundation.

Zapco has a reputation for sound reproduction and quality that is unsurpassed. It is our dedication to sonic purity and our passion for performance that built that reputation — just check the audio competition scene and the forums; the pros know what to use to win.

But not everyone wants to compete. Could Zapco put its 40 years of audio experience to work to develop an amp for everyday use — one that all can afford but that stays true to the Zapco heritage for sound and reliability? Absolutely. With the Studio-B amplifiers, Zapco brings the sound quality and reliability that built the legend to an amplifier everyone can afford.
