ASTOR AS-XP99EZII. Tube Preamplifier

The EZ series uses Alps Electric Co., Ltd.'s attenuator type 41-contact semi-custom-made VR for the volume, RJ-232 for the input terminal, and INLET® rhodium type for AC. The coupling capacitor uses the AMCO type metallized film capacitor manufactured 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. The insulator is machined from a 50mm oxygen-free copper round bar and attached with young cowhide sandwiched between the bottom plate. It converts the sound of analog playback into an even more wonderful and excellent sound quality.
The new AS-XP99EZII. has a higher grade transformer from PT-95 to PT-150, and the impedance and frequency response have also been improved.

The chassis is made without any screws, and the metal fittings of the 2 mm thick oxygen-free plate are used, the XP type 2 mm thick mirror stainless steel plate that has been folded is used, and all carefully selected parts can be removed, making it the same as the two-piece structural principle, and it is also remarkably effective in anti-vibration and noise countermeasures. The sound quality shows the characteristic of being able to reproduce the frequency from 10Hz ~ 80kHz almost flat so that the original sound can be faithfully reproduced.
