Transparent, high quality sound, faithful reproduction of original sound

Further transparency, further improvement of sound quality


The chassis of the AS-KT88LC is made of 2mm-thick 18-18 stainless steel with a mirror finish, and the internal mounting parts are made of 2mm-thick 18-18 stainless steel with a mirror finish and 2mm-thick oxygen-free copper material. This robust and beautiful mirror-finished casing alone cost nearly 200,000 yen, but it is remarkably effective in anti-vibration and noise reduction. The heat dissipation is also very good, so even though it is a vacuum tube amplifier, it can be used for a long time without any problem at all. The insulator is made of oxygen-free round copper rod and attached with young cowhide leather. The circuit parts are manufactured using carefully selected parts that are good for sound quality. The vacuum tube mounting precision is also extremely high, and noise generated from the tube mounting area is suppressed as much as possible.

The AS-KT88LC is a single, delicate, detailed, and highly transparent expression, but with the use of a choke coil, the sound is thickened and the original sound is reproduced with high fidelity. The AS-KT88LC aims to reproduce the original sound with increased depth of sound.

The AS-KT88LC is equipped with a switch for current adjustment, which allows you to adjust the tube current by about 10mA by switching between 240Ω and 300Ω, allowing you to enjoy the tube current according to your preference.
