AMPEX 601 1950年代 真空管前级扩大机一对
有一个旋钮，缺了一小块。
一声道音量控制旋转时有沙沙声。
其中12AY7 目前用5965替代
一台用8支真空管，两台总共16支真空管。

大提琴声音质细腻，走向中性均衡
钢琴质地细致缜密，音符的重量感与密度感颇佳
人生唱起歌来更是韵味十足
歌声尾韵的细微变化，丝丝入扣，不禁为之迷醉。
，充满磁性的浑厚嗓音，低沈而有韵味，
小提琴昂扬而不刺激，稍微明亮的光泽
铃鼓声音时轻时重的声响，清晰的力度变化，
几乎可以看见摇铃的那只手是如何地动作，
拍击时瞬间能量的冲击更是让人精神一振；不止这样，
木琴演奏时可以感受出敲到在木键上的细节，
还把铜管共鸣的短暂余韵完整呈现，让琴键的形体变得好大一颗；
合奏的时刻，所有的乐器又能配合无间地唱和著。

One knob is missing a small piece.
The volume control for one channel makes a hissing sound when turned.

Purchase includes a free HI-END commemorative CD from the Kaohsiung International Audio Show.
The cello has a delicate, neutral, and balanced sound.
The piano has a refined and meticulous texture, with excellent weight and density in the notes.
The vocals are particularly captivating when sung.
The subtle changes in the vocal endings are exquisite and mesmerizing.
A deep, resonant voice, magnetic and full of charm;
The violin, uplifting yet gentle, with a slightly bright sheen;
The tambourine's sound, varying in volume and with clear dynamic changes;
You can almost see the hand moving the tambourine;
The instantaneous energy impact of each strike is exhilarating. Moreover,
When playing the xylophone, you can feel the details of each strike on the wooden keys;
It also perfectly captures the brief resonance of the brass instruments, making each key appear remarkably large;
In ensemble performances, all the instruments harmonize seamlessly.
