High end integrated amplifer
A pre-amplifier that aims to reproduce the original sound
Description
The chassis of the AS-KT88PMS is made without any screws on the surface, bent and finished with 2mm thick 18-18 stainless steel mirror finish, and the internal mounting parts are made of 2mm thick 18-18 stainless steel mirror finish material and 2mm thick oxygen-free copper material. This sturdy and beautiful mirror-finished casing alone cost nearly 200,000 yen, but it is remarkably effective in preventing vibration and noise. The heat dissipation is also very good, so even though it is a tube amplifier, there is no problem at all even after long hours of use. The foot base is made from oxygen-free copper round bar with young cowhide sandwiched between it and the chassis. The circuit components are carefully selected for their excellent sound quality. The vacuum tube mounting accuracy is extremely high, and the noise generated from the vacuum tube mounting area is suppressed as much as possible. Artistic wiring with no waste eliminates noise pickup due to wiring.
Most audiophiles choose separate amplifiers because they prioritize sound quality, but the AS-KT88PMS is the perfect pre-amplifier for those who want to get the best sound possible, despite the installation problems and the hassle of splitting the system into two units. The sound quality is the same as that of other ASTOR high-end amplifiers, with no noise, no muddiness, clear and transparent sound quality, and faithful reproduction of the original sound.
The self-biasing capacitors used by ASTOR are an order of magnitude larger than the 200-300 micro capacitors used in most amplifiers, but 8000 micro capacitors are used. This allows the sound to be well expressed even when the volume is turned down.
