30年前架生要好小心。

可能整過N次，未必用原裝材料。

除非熟識賣家，又可以睇吓內籠有冇摩機，否則…….

The *Krell KBL Signature* preamplifier was released in *1990*⁽¹⁾.

In terms of sound quality, the KBL Signature is often praised for its *dynamic and transparent sound*⁽¹⁾. When compared to modern preamps in the same price range, it still holds up well, offering a *powerful and detailed audio experience*⁽²⁾. However, newer models might have additional features like remote control and improved ergonomics.

Copilot 答的！

請問有人知道krell KBL signature 是那年面世的前級. 声音質素同現在同價前級輸多少 ？
