TO-KT88KGIN Multi input Power amplifier

TO-KT88KGIN is a power amplifier jointly designed by Exclusive Audio and Astro Electronics. It is designed to meet the needs of users who do not listen to vinyl records but wish to use a single amplifier for multiple players like a pre-main amplifier. Since the phono equalizer function is omitted, it contributes to a significant cost reduction.

The products are carefully crafted one by one by skilled craftsmen using carefully selected materials with their skills, and since the brand boasts a beautiful appearance, abundant information, and pure sound, the internal parts of the amplifier are carefully selected just like those of high-end models, resulting in an amplifier that exceeds its price and produces high sound quality close to that of high-end models. With Astro Denshi's unique noise processing and the highly transparent and unadorned reproduction of the original sound inherited from the high-end models, it also has a wide range of nostalgia that can handle any genre of music without any difficulty.

By adding three inputs to the power amplifier, multiple devices such as CD players, tuners, smartphones, and tablets can be connected, allowing it to be used like a pre-main amplifier. Of course, by connecting a preamplifier, it can be used in a more versatile way.

The output tubes are equipped with a self-bias function, so they can be easily replaced with compatible spheres for your enjoyment. The self-bias capacitor used by Astro Denshi Kikaku is an order of magnitude larger than the 200~300 micro capacitors used by most other manufacturers, at 8000 micro. This allows the sound to be expressed well even when the volume is turned down.

This power amplifier is designed to be used without a preamplifier. Astro Denshi Kikaku's power amplifiers are equipped with separate volume controls for left and right channels in order to achieve balance, and this function is utilized to add three inputs so that music can be enjoyed directly from the player without a preamplifier. The sound is sharp and consistent, with the vacuum tubes all dropped in from the main chassis and secured by a thick, beautifully anodized front panel to prevent vibrations. The aluminum chassis, which is strong enough to hold up to the powerful and thick energy of the KT88 tubes, produces a bright, clear sound with no muddiness. The sound is bright, muddy, and clear, and can be enjoyed even without a preamplifier.
