Translation ofTechnical Hobbies City University of Hong Kong CTL3352 Scientific and Technical Translation Ivan Yeung What is Super Audio CD?SACD 是甚麼？ It looks just like a normal CD, but that’s where the similarity ends. The SACD difference is breathtaking. The difference in sound quality is so great that you have to hear it to believe it! 它看來像一張普通的雷射唱片，但共通點就僅此而已。SACD 的差別教人屏息靜氣。音質差別之大，未曾親耳聽過，實在難以置信！ Thanks to revolutionary technology called Direct Stream Digital (DSD) encoding, SACD represents the highest quality sound source available today. 有賴革命性的直接串流數碼 (Direct Stream Digital, DSD) 編碼技術，SACD 是今時今日頂班音質的音源 *。 Thanks to an amazing 2,822,400 samples per second, you get audio performance that no other format can deliver. 有賴每秒 2,822,400 次採樣， SACD 可達至其他制式難望項背的音響表現。 Not just a CD, but a better CD非同凡響的 CD Time for fun! For example, the frequency response delivered by DSD is almost five times greater than that delivered by normal CD. While CD frequency response extends to 20,000Hz, DSD technology can theoretically reach 100,000Hz. 舉例說，DSD 提供的頻率響應幾乎為傳統雷射唱片的五倍。CD 的頻應可達 20,000 赫 / 週*，理論上，DSD 技術卻可達 100,000 赫。 And with a dynamic range of 120dB compared to 96dB on CD, Super Audio CD goes right to the limits of human hearing and beyond. 雷射唱片的動態範圍只有 96 分貝，而 SACD 的動態範圍則達到 120 分貝，超越能聽範圍，直抵人類聽覺極限。 VTV Octal Line Stage Project真空管樂園八腳管高電平前級 (設計) After a dozen years of listening to “peanut tube” preamps using 12AX7s or 6DJ8s, I asked Eric Barbour to design a simple, good sounding octal-based preamp. 聽了使用 12AX7 或 6DJ8 的「花生管」前置放大器多年，我請艾力巴布爾設計一個既簡單，音質又高的八腳管前置放大器。 VTV Octal Line Stage Project真空管樂園八腳管高電平前級 As many of you know, the reason there are so many “peanut tube” preamps is because these tubes are small and cheap. 眾所周知，市面上有那麼多的「花生管」前置放大器，是因為這些管子細小便宜。 眾所周知，市面上的「花生管」前置放大器那麼多，是因為這些管子細小便宜。 Time for fun! By the way, so is their sonic performance. 但所謂一分錢一分貨，音效方面就自不用說了。 順帶一提，它們的音效也不外如是。 VTV Octal Line Stage Project 真空管樂園八腳管高電平前級 Miniature dual triode tubes typically have a small soundst
