Can headphone amp be used as a pre-amp (competent enough) for speaker systems ?
Sorry for not being able to type Chinese in office.I am considering to buy a Heed Canamp for my K701 and it seems this amp can also be used as a pre-amp (for the speaker systems).
So,,, does anybody here has used it as a pre-amp ? (I mean, as a pre-amp, is it worth 3000 rmb ?) Or, generally speaking, when a headphone amp is used as a pre-amp, is it (almost) as good as a pure pre-amp (or the one in the integrated amp) of the same price ?
To be more concrete, now integrated amp I own Marantz PM8003, in your opinion, is that possible the 2nd combo (see hereafter) sounds better than the 1st one?
1. SA8003->PM8003->Speakers,
2. SA8003->Canamp->PM8003->Speakers
Thanks for your feedbacks ! Will have a try and come back 2 u later~~~ 耳放都是可以用做前级的,有些背后有PRE-OUT,有些没有,但可以从耳机插孔取信号,转为RCA,这样等于也把耳放作为前级放大器用,都没有问题. 呵呵，人家LZ不能打中文不代表LZ不懂中文啊 对方用什么语言跟你说话,你就用什么语言回答(如果你能够的话),这是一个人际交流的礼节,但我不确定这个礼节在本贴的情况下是否适用. :P 倒过来成立么？是不是所有的前级都可以做耳放？接口转换一下。 谢谢大家的回复。可能的话，我当然希望大家用中文回复:) 原帖由 爱乐人生 于 2009-10-23 20:01 发表 http://bbs.headphoneclub.com/images/common/back.gif

同问，我也很好奇如果从前级引个出口来是不是就可以接耳机？
其实这又引出了一个新问题，合并功放的耳机输出，是内部前级的输出，还是从内部的后级衰减（比如串阻？）后引出的输出？ 刚才试了一下。
meridian 508.24 rca到Heed Canamp的line in，再从Canamp的line out 到偶的V8，推D7000。
声音没有很大的区别，但能感觉到声音里多了一丝Canamp的风格。中频更加温暖厚实，多了一份热情的染色，听人声更迷人更有味道，但整体解析和透明度降了些，低频速度慢了些，混了些。总体感觉按照偶的口味，不如508.24直接输入到V8。但若想要系统播人声更好听的话，加个Canamp是个好办法。 原帖由 lus12 于 2009-10-24 04:15 发表 http://bbs.headphoneclub.com/images/common/back.gif

两种情况都有. 1. SA8003->PM8003->Speakers,
2. SA8003->Canamp->PM8003->Speakers
As to the 2nd combo
i donot think it's a good idea to bypass the PM8003's pre module and use your headphone amp to do the work
unless you've got a very good pre module in the headphone amp 多用一条信号线 会多出来很多麻烦
另外耳放的前级部分和合并功放后级输入之间的阻抗匹配也会是一个大问题
不搭的可能性远大于中奖
