ASTOR AS-XP88EZII. Tube Preamplifier

Alps Electric Co., Ltd. uses an attenuator type 41-contact semi-custom-made VR for the volume of the EZII series. The input terminal is RJ-232, the AC is the INLET® rhodium type, and the coupling capacitor is the AMCO type metallized film capacitor made by Amtrans. For the electrolytic block capacitor, a semi-custom-made product made by Nichicon is used to form a stable B power supply circuit. All parts are carefully selected and used with reliable parts, and each one is completely handmade and manufactured. It converts the sound of analog playback into an even more wonderful and excellent sound quality.

We make a chassis that does not use any screws, use metal fittings of 2 mm thick oxygen-free plates, use XP-type 2 mm thick mirror stainless steel plates that have been folded in, and make a two-piece structure by removing all carefully selected parts, which is remarkably effective in anti-vibration and noise countermeasures. The sound quality shows the characteristic of being able to reproduce the frequency almost flat from 10Hz ~ 100kHz so that the original sound can be faithfully reproduced. The foot is machined from a 50mm oxygen-free copper round rod, and young cowhide leather is sandwiched between the bottom plate to support further vibration control.
