| [#22] 用假balance output 音質有冇改善???? 而平衡放大，必須保證冷熱端放大元件的嚴格一致，但以目前的技術能力不可能達到。 None of device can be 100% matched, left and right cannot be identical, so as balance channels. It happens to unbalanced amp too. But the situation can be remedied by careful circuit design. Technique commonly being used are feedback. Feedback can be in various form. e.g. feed part of non-inverted signal negatively to inverted signal within a differential pair to achieve better matching, and hence low distortion. For unbalanced amp, options are less, most of the time, just employ negative feedback. A technique that is known for poor sound. |

| [#23] 用假balance output 音質有冇改善???? hifi界就是有一種亂套理論、亂發展理論的傳統。 I'm not going to say balance must be necessary superior, because there are many other factors. Just think the writer has made a conclusion based on some mis-understanding on the technique. |
