A-300<\/b>\u00a0mono power amplifier\u00a0.\u00a0The novelty will go on sale at the end of October, however, so far only in Japan.\u00a0The price is quite consistent with the ultimatum status of the amplifier and will amount to almost three million yen (\u00a52,970,000) for a pair of monoblocks.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter\"

replace the A-250 monoblocks, which led the lineup for five years.\u00a0This pure transistor amplifier operates in pure class A, delivering 125 watts of power when driven into an 8 ohm load.\u00a0With a drop in load resistance, the output power of the novelty grows linearly &#8211; at a load of 4 ohms, the amplifier produces 250 watts, 2 ohms &#8211; 500 watts, 1 ohm &#8211; 1 kW!<\/p>\n<p>Such amazing characteristics are provided by parallel-operating push-pull output stages, built on two dozen specially matched pairs of MOSFET transistors.\u00a0This solution made it possible to achieve high output power with record values \u200b\u200bof the signal-to-noise parameter and a low level of distortion.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.stereoindex.com\/tech\/wp-content\/uploads\/2022\/10\/187_techweek.jpg\" alt=\"Image\" \/><\/p>\n<p>The Accuphase A-300 power supply is based on a powerful toroidal transformer and a capacitor bank with a total capacity of 100 thousand microfarads.\u00a0The damping factor of the amplifier reaches 1,000 units, which allows the novelty to cope with the heaviest load.\u00a0The weight of one monoblock is an impressive 46 kg.<\/p>\n<!-- FeedbackWP Plugin --><div        class=\"rmp-widgets-container rmp-wp-plugin rmp-main-container js-rmp-widgets-container
