amp应该要比耳机贵的
但是贵两倍以上就没意思了
hd650也不是高烧了
才300刀
高烧可以烧grado的旗舰,或者akg k1000,大奥,。。。。恩,还是换箱子烧吧
anyway,hifi这东西100刀和200刀的区别远远超过1000刀和一百刀的区别
大概performane=log($/C) C是一个常数,$是价钱
国内的amp确有好的,无论胆机或者石机
可以去headfi上看,老美对很多国内的amp都有好评
设备跟你听的音乐也很有关系,这是品味的区别,不是优劣
了。 |

V*****n 发帖数: 893 | 3 congrats! from my limited knowledge on amps, this is a great amp for the
money. quality of power is more important than quantity. also, power rating
is not really a good indicator of capabilities. Simaudio, being one of the
greats, will definitely rate their product conservatively.
on a side note, judging the adequacy of the amp (power wise) also need to
take the speaker efficiency into account, as BBKing did. It is true that big
speakers can handle a lot more power and has more loudness potenti |

V*****n 发帖数: 893 | 4 damaging the speakers or not has nothing to do with the rated power of your
amps. it's all in your volume control. if the amp is underpowered, high
volume damages your tweeter by clipping. if the amp is overpowered, high
volume damages your woofers by exceeding excursion limits. |

k********u 发帖数: 2209 | 7 不是很烧这个,只知道direct drive要好于belt drive的,音质和盘的录制和
condition关系很大。大部分不是冲着音质的。
本来就是模拟信号,不需要DAC,带pre-amp(或者叫phono-amp)的才可以直接接耳放。
否则的话,需要专门找个专门的amp,或者找个带phono输入的receiver。 |

k******8 发帖数: 913 | 9 I have se530, IE8 and westone 3 now, and had TF10 before.
Sound wise, I like IE8 most, best bass, soundstage and impact. IE8's mid is
not as good as se530, but not far away either. Treble and sound transparent
are the only shortcomings of IE8 IMHO, TF10 shines in those two areas.
An amp is really needed if you wanna hear the real IE8. I am using IPV -> iB

L*****k 发帖数: 13042 | 10 没啥区别。
receiver一般是集成功放(integrated amp)带收音机。
amplifier可以指集成功放或者纯后级(power amp)。
家庭影院可以买receiver,也可以买multi-channel sound processor
(多声道前级,负责解码,数模转换和音量控制)+power amp,
如果receiver有解码输出,也可以再接后级提高效果。 |

If it's a headphone amp incorporated, probably not low level.), yes, you

EQ probably OK. Lumped amps normally result in terrible SNR and dynamic

w**t 发帖数: 1037 | 17 jeff rowland的amp 几年前 已经全面转向class D .不再是傻大粗,看起来很小巧,做工
像是艺术品.
很对我的口味.
由于接头的关系,现在没法仔细听,只能从旮旯里翻出对10年前从radioshack买的奇细无
比的裸线
绑在201的post 上.前级也没法接.听得时间也不多,所以随便说两句第一印象.
即便如此,一开声还是给我很大惊喜. 我实在不擅长用文字描绘听感.只能说很好听.比
我用过的
krell 400xi, simauido W3, proceed amp3 有很明显提高. 音色算是优美类型的, 丝
毫不会有
冷声的感觉.反倒有点warm. 最明显感觉音场左右前后大了很多,听交响和室内乐时乐器
分离和定位很准.低频尤其是鼓声也明显更结实,更有弹性,目前感觉就这么多吧.
如果对class D amp 还有疑问,相信听过jeff rowland的公房会改变看法的.至少他家做
的class D amp的声音算是hi-end 级.

长期潜水,看了今天的争论,也来说说solo。
感觉liulinglll并没有参加团购,说团购是山寨可能有失偏颇。
这个Dotaallstars关于solo是妖风的言论确实有很大问题。solo从90年代中期出世以来
一直受到欧美发烧友的好评,近20年了用户越来越多。森海也鉴于solo的整体素质把
solo一直作为自己旗舰的reference amp,各种展示会都被采用为森海的御用amp。这就
已经说明了solo的素质。国际第一hifi耳机大厂选一个不靠谱的二房配自己的旗舰,难

有一点要明确,国内安润也是近几年才引进的solo。以前鉴于国内10年前的消费水平,
能舍得花钱买solo级别二房的人应该很少很少。所以如果说是安润造就了solo的兴起,

life span of audio gear (my opinion);
cable (forever, if well taken care of) > speaker (20-30 years) > SS pre-amp

you could probably still buy it.. but be ready to expect the worst. |

还有,我不明白,你为什么一口咬定以前的deck 不可能放headphone amp 进去? |

d*******n 发帖数: 2078 | 24 你是说了半天,还是认为卡座限制了耳机接口。最关键的一点,你不懂平行的线路。
简单的说,一个FiiO 的耳放,放到卡座里面,用卡座的电源供电,然后连到卡座的耳
机的接口去。这能不能实现?我负责的说,这个我都能改装。如果这个能行,就没有什
么卡座本身的限制问题。整个线路,更磁带部分可以不产生任何关系。
给你贴的图,你也没有好好学习。那里面的headphone 接口,就没有经过record

1.煲的时间长。有哥们说煲好的701跟没煲好的简直不是一个娘生的 google原话应该能

2.amp 电流输出大
耳机上攀比浮夸之声甚大~ 3000rmb的amp来推也就最多入个门的级别。但是amazon和

闲,我就来介绍介绍我用过的几套系统,当然大部分都是Linn系统,为版面做一些贡献
,也为感兴趣的朋友搭配系统提供一些参考。
我的第一套hifi系统是耳机系统,2004-2008年使用的,当时最早从一个Senheiser
HD477升级到了HD600,也从电脑hifi转移到了台式机,用了当时非常受欢迎的马兰士
CD17 Mkiii,搭配了国内森海代理商推荐的HP2000胆石混合耳放。那一套系统,声音还
是非常讨喜的,我至今都还记得,邓丽君的嗓音甜的如同台湾店里卖的珍珠奶茶一般。
其次是声音很厚重很结实,听大动态的交响乐,比如德沃夏克的第九,轰的我相当过瘾
。但是低音的控制力不是特别好,没什么太多的质感。HP2000当时在国内也不算是推
HD600最好的耳放,也就基本将就着听了。2008年出国了,台式机和耳放都没法带走,
于是台式机给了父母,变成了他们音响系统的一部分,耳放变成了他们的音响前级,后
级是当时一个和翔声合作做功放的DIY朋友推荐的,翔声的KT88,推一对infinity的落

置,所以决定搞一套2声道一体功放+音箱的配置。
很快在Craigslist上面看到有人在卖一对Paradigm的mini MK II,也就是mini monitor
的前身,要价125刀。我最后砍到100刀成交。付钱时看到卖家笑得像花一样,很有买亏
了的感觉。这个还没有带Stand,卖家说搬家的时候扔了,否则就一起给我了,听得我
很吐血。
于是继续找,发现有人在卖一对Klipsch的音箱+Stand,只要40刀。没有给型号,只给
了照片。查了一下,觉得比较像是KG2,于是冲过去收了。发现这实际是KM2,喇叭都是
好的,但是其中一个喇叭边缘跟箱体之间填有胶,估计是修过,不过感觉已经超值了。
