SONY TA 444ESX extra high standard Integrated am

As a standard amplifier of the ES series, this pre-main amplifier was developed by inheriting the design philosophy of the high-grade equipment.

Pursuing the ideal of non-vibration and non-resonance design, we have adopted an Advanced Furniture Tuned G (Gibraltar) chassis that thoroughly pursues the material selection, shape and structure.
In the G chassis, calcium carbonate, the main component of marble, is added to unsaturated polyester and reinforced with glass fiber. Compared with metal, this material has superior vibration damping characteristics with greater internal loss, high strength, and high precision machining is possible. By shaping this material into an acoustically well-examined shape, excellent rigidity is obtained.
