The amplifier is designed with artistic wiring, a robust chassis construction for vibration suppression, and other unique ideas to suppress noise generation in pursuit of a more informative and purer sound quality. The amplifier components are carefully selected and manufactured in the same way as those used in higher-end models, resulting in an amplifier that delivers a high quality sound that brings out the full appeal of the 300B.

AS-300BsB is a single-shot minority amplifier series. The chassis is a low-priced product with a limited number of units using 5052 aluminum alloy of 1.2 mm, 1.6 mm, and 2 mm thicknesses, respectively. The transformers are the same high-grade Hashimoto transformers used by Astro Electronic Planning in their high-end models.
The left and right independent volume controls allow you to connect directly to CD players, smartphones, tablets, etc. without a preamplifier and enjoy the high quality sound of the 300B vacuum tube easily.
