Dr. Z Amplifiers philosophy is simple: Hand-build a top quality original product, designed to last a lifetime, which becomes an extension of the players’ personality and sound. Dr. Z Amplifiers uses only the best components available to build professional quality products at prices that are very competitive for hand-built, point-to-point wired, U.S.A. made amplifiers. Every Dr. Z amplifier and speaker cabinet is engineered and constructed with the greatest attention to detail and sound. Dr. Z products compare very favorably against other manufacturers’ amplifiers; a fact that has been proven time and again in ‘amp shootouts’ over the past decade.
