Our production amplifiers represent our most thoroughly tested designs. We have created push-pull and Single-ended tube designs at a variety of power levels to allow you to select the ideal amplifier for your system. Enough samples of each design have been manufactured to maximize their sonic potential. The Ampsandsound sonic signature closely approximates the best aspects of the classic tube sound of the 50s (maximum midrange bloom), supplementing it with a modern bass signature and transient speed. We have chosen a few of our favorite designs to bring to market. In general, we partner moderate efficiency speakers with tube amps of low to modest output to provide high-end sound at reasonable prices.
