First of all, it is a splendid stainless steel chassis that has been polished like a mirror.
Stainless steel is an alloy of iron and chromium-nickel, and the higher the ratio of chromium and nickel, the higher the quality and high-grade stainless steel. The stainless steel used by Astro Electronics has an 18-18 blending ratio. The stainless steel of general tableware is 18-8 and 18-10, and it seems that the cutlery is of quite high quality, so Astro Electronics' stainless steel chassis is quite a luxury product. You can see it when you touch it, but it is so smooth that it feels good.
The thickness of stainless steel is 2 mm and 3 mm (VIP, SP, MK series) and is quite thick.
By bending the extremely hard stainless steel with a special technology, it is finished in a seamless and robust chassis, which is a characteristic of Astro Electronics.
This sturdy and beautiful chassis, combined with its weight (very heavy), has a damping effect.
At this point, the amount of money is considerable, and when it comes to a full-size amplifier, the chassis alone is about 200,000 yen! It will also be.
In addition, Astro Electronics uses oxygen-free copper plates or 18-18 stainless steel inside the stainless steel housing for reinforcement or mounting parts in a two-stage structure. Mirror finish, of course.
