专业和民用功放哪个更好? [复制链接]

1#
同是五千元的专业和民用功放哪个更好?
同样推中高灵敏度的落地箱(88-93DB)
请大家从各方面阐述一下观点

家里用当然要用民用功放。

有米的话,可以考滤用录音室监听功放

专业功放和调音台我都玩过,早期的一些原装美国和英国的产品还过得去,我玩过QSC,EV,百威、皇冠、声艺、声迹等,但都有一问题·用小功率去推家用音箱不好听,细节的表现也不是很理想,由于是电路的原因能否摩得上去就不敢说了.

专业通常是乙类机,声音明亮,动态好,但不耐听.民用通常是甲类或甲乙类,声音耐听.

和老兄同感.我搞了十一年专业.

总觉得家用器材音染大

不只大家想过没?用有素质的前级(调和)+专业后级(用它的大力.摩一下.)

从声音准确还原角度讲.民用不是对手.民用是要讨好人耳(加不同的声染).无特定标准.故产生很多风格.因人而异.而专业是有一套技术标准的.所谓的泛音.摄人的低频都是造出来的.录音室专业监听器材只讲原音传输.功率放大器本来就是负责信号放大.要其它的就用调音台,混响器,激励器,压限器等.民用本来就是专业衍生出来的.一套民用远不是专业对手.同价位.
只不过大家不是在搞录音.又喜欢美丽声染.就认为专业不好.
我个人就排斥假声.个人观点.不同意的就砸砖.呵呵......虚心接受

所以我现在也是胆前级配皇冠甲乙后级

呵呵.绝好的理念.

专业功放用小功率去推家用音箱不好听,细节的表现也不是很理想,这方面还是胆机强

专业机注重大功率,民用HIFI机比较注重细微的东西~~

言之有理!
