ASTOR
AS-XP88EZ�U Tube Preamplifier

Alps Electric Co., Ltd. attenuator type 41 contact semi-custom VR is used for the EZII series volume. RJ-232 input terminal, INLET(R) rhodium type for AC, and AMCO type metallized film capacitor made by AMTRANCE are used for coupling capacitor. The electrolytic block capacitors are semi-custom-made by Nichicon to form a stable B power circuit. All parts are carefully selected for reliability, and each unit is completely handmade. The sound quality of analog playback is further enhanced by the excellent sound quality.

The chassis is made without any screws, and uses 2mm thick oxygen-free metal fittings, folded XP type 2mm thick mirror-finish stainless steel plates, and carefully selected parts are all installed to create a two-piece structure, which provides excellent anti-vibration and noise reduction. The sound quality is characterized by an almost flat frequency reproduction from 10Hz to 100kHz to reproduce the original sound faithfully. The foot is machined from a 50mm oxygen-free copper round bar, and is attached to the bottom plate with a piece of young cowhide leather in between for further vibration suppression.
