无缺陷电路和X2 Symasym5-3这两个电路哪一个更好？
本帖最后由 aaaszx 于 2024-4-15 16:18 编辑无缺陷电路和X2 Symasym5-3这两个电路都是经典的功放电路，不知道哪一个更好？做过的坛友请来指点指点。 两个一起做出来比较。 做过X2 Symasym5-3，没有做过无缺陷。看电路输入级都是差分电路，电压放大级有区别，X2还是差分，无缺陷是恒流源负载的单端放大。不知道哪个更好 几年前完过,C2 47uy以下 音质最美,有几分胆味感觉, 唯一缺点就是低音 有些浑浊不清, aaaszx 发表于 2024-4-15 09:28

用我的，包你耳目一新。 第二个更好 无缺陷那个，R22用恒流二极管，代替更好，对电源纹波抑制能力，极大的增强 无缺陷的那个，我也折腾了好几年
无缺陷失真小，但过载失真大 yidayong6 发表于 2024-4-15 18:26

什么感觉呢 无缺陷做对了对各种音乐的适应性都很好，更保真，偏监听风格，注意电压不能太低。
Symasym5-3播放某些音乐更好听，偏科。 还是用简单的全对称吧，输入级电阻代替恒流的那种，调好了会让人另眼相看

无缺玩了一年的样子失败了（自己水平问题），最后是筑明给了2块无缺的板子和些许零件装上去才成功。再后来用自己设计的电流模电路，无论是速度，带宽，灵敏度都比无缺好，中点可以调节到1mV以下（现在一声道0.3mV，另一声道0.6mV）。图纸不在乎多，玩熟它才是真的。 HIFI5200 发表于 2024-4-16 09:18

一下发这么多不知道你要表达什么意思，好像看到你在“OPA1612交越失真”贴里也发了 看了“OPA612交越失真”贴，我依据这个思路把他加到了“无缺陷”电路里，做了一个仿真，输出级不截止，推动级到1.5Vp输入不截止。大家看看就好，行不行我不知道，估计热稳定性会有问题。
