Astro
LD-CX54KS Preamp

The LD-CX54KS has a 1.2mm-thick aluminum chassis and 2mm-thick 52S aluminum alloy internal component mounting fittings are produced and machined to create a double-layer structure to prevent resonance generated from the inside and outside, thereby improving sound quality. In addition, the legs are made of a combination of aluminum and rubber materials. The use of carefully selected materials, including circuit components and chassis mounting parts, also contributes to the pursuit of high sound quality. In addition, the knobs for the VR are made of 52S aluminum alloy blocks, and the entire panel is made of 10mm-thick 52S aluminum alloy, with a beautiful anodized finish for a good appearance and a solid weight for a stable, high quality amplifier.

Astro Denshi's original artistic wiring, robust chassis construction for vibration suppression, and unique ideas are used to suppress noise generation in pursuit of more information and higher purity of sound quality. The internal parts of the amplifier are carefully selected and manufactured one by one by skilled craftsmen, just as in high-end models. The clear space with no clutter, high resolution and beautifully extended resonance, and natural and crisp sound with no coloration make this amplifier far beyond its price, even though it is in the low price range.
