大家好，LM1875好还是TDA2030好？

这还用问？当然是1875好了，去看看它们的datasheet就知道了。国半的芯片好

老鸟都说1875好，，我也菜鸟一个

都是真品的情况下，1875听起来舒服。因为电路上1875和2030几乎是同等替换，所以1875的假货泛滥，很多都是2030打磨而来。

把IC第二脚的电容短路掉，如果没烧掉照样出声，而且出更好声的就是正品LM1875，TDA2030不在同一档次，不能拿来比，不过声音也是不错的。TDA2030购买的时候要注意厂家，原产是ST的，而国产的基本不能听。

2030a不错的说

都好啊，只是功放大小不一样吧。

集成块功放1875比较好，LM3886人声最好，这几种功放我都听过。

从技术指标来说1875要好，但最终出来的声音是电路决定的。

这个看你推什么负载，1875耐压及功率比2030高

就是不知道2030A都发展30多年了，烦什么还没有消失

刚刚玩过tda7375，感觉比2030好多了；外围少，功率大；音质不错；BTL比“小余”的2030BTL好得多

Via Jason and Michael and Johanna ... yes everyone is talking about it ...,Office 2010 Activation Key

John Sumser of the Electronic Recruiting News lists the “best 20 or so new blogs” about “recruiting,Windows 7 Professional, job hunting,Microsoft Office 2010, and HR.” <The list doesn’t really include “new” blogs as some have been around for quite while.>

But no Heather or Gretchen. Poo. Does John not like us anymore? I remember a time early on in our inception when John thought we were neat .. or at least "facinating." ;-) In fact,Discount Windows 7, I even sited his two mentions of JobsBlog in my 2004 performance review. (Yes,Microsoft Office 2007, I’m a dork; I write very thorough and lengthy reviews.) I guess no kudos from John for my 2005 review.

It's ok. I'll survive. Time to go home and wash away my worries with a fine glass of wine.

gretchen

By the way,Windows 7 Home Premium Activation, I write this post in jest. I regularly read most of the blogs on John's list,Microsoft Office 2007, and they are quite good and deserving. You should check them out as well .... Just keep reading me,Office Professional 2007 Key, too,Windows 7 Product Key, though.

Please ... ;-)

1875中高频密度感比较好 2030低频控制力比较好按自己需求选择了

1875个人比较喜欢

chenzy_ptv · 发表于 2011-8-26 20:54

我家的功放是2030的，看啦各位的意见，想自己整一套1875玩玩，就当练手啦，谁叫自己是菜鸟呢！
