的方式推比较好，请问各位有经验的高手biwiring能带来的好处到底在哪里？ |

发帖数: 672 | 2 receiver上有speaker set A 和 Speaker set B，说明书上也说可以同时play set A +
B。那么如果音箱有两对接线柱，能不能把这两对接线柱分别连接在set A 和 set B
上，然后让receiver play set A + B, 反正信号是一样的，这样Biwire行不行呢？还
是Biwire必须连接同一个speaker set A or B。这样做的差别在哪儿呢？ |

发帖数: 8974 | 3 这个……我同意
只是我没头没脑的尝试的太多了，呵呵，所以想听有经验的人解释一下
另一个原因是，我在网上又找到一个一模一样的st-140，正在犹豫要不要出手，嘿嘿，
恶魔啊
biwiring一定要两个一样的功放推吗？需不需要用到balanced output之类的？ |

发帖数: 672 | 4 thank you very much Jwalk, you are always answering my stupid questions. I
do have an extra pair of speaker wires, and last night I just biwired my CM5
using only one speaker outlet. I think they sounded better than just single
wired. I just realized I now have two complete set of speakers. the Hk3490+
Bose901 and the Marantz NR1603+CM5. With two receiver I think I can try to
biamp my CM5, but my concern is their power differ too much. The HK3490 will
output 120W per channel while the NR1603 is ... 阅读全帖 |

I currently have 7.2 biwiring capable onkyo receiver, with 7 speaker setup.
(no sub since still in apartment right now) Front speakers biwireable.
I read online from avr forum and such, states that biwiring does not provide
too much of a sound improvement, so if you can do 7.2 setup, you should go
with 7.2 instead of 5.2 biwiring.
You are getting a much better sound by doing biwiring? if so maybe I will
try it sometime.

发帖数: 75 | 7 网上也又很多做bi-wiring的例子。
你看你家喇叭是不是可以做biwiring的，一般都是2对输入接口，用一个金属片连起来
了。 如果单线链接就直接连到任何
一个接口就行了，但是如果你要做biwiring, 就要拿开金属片，你功放的front speak
链接到喇叭的上面的口，surround
back（注意是surround back, 不是back speakers)链接下面的，然后你的功放要调成
可以送biwiring的输出就可以了
（这个你要看onkyo的menu,我的是yamaha,不同）。
这样链接的好处是高音更高，中音更清，我把低音都放到低音炮了，这样不会mix在一
起。听起来非常有层次感。 |

发帖数: 3139 | 8 金属片和线都是一样的，就是起个并联高低音线路的作用。我以为你问的问题是，为什
么不用那个金属片或者线，也能响，有的箱子其实那个金属片做在箱子里面了，说自己
是biwire compatible，只接一条线的时候，里面有jumper。接两条线的时候，压降为0
，jumper就没用了。
有的厂家把jumper做到外面，叫biwire connector，外面的贴片或者线就是必要的。 |

发帖数: 75 | 9 if you already have 7.0 (hehe, since you don't have the sub yet). you
shouldn't do the biwiring.
birwiring is good for the 7.1 receiver but with only 5.1 set ups. you have
to give up surround back speaker to
do this way. but for me, i can hear the big time difference.
7.2 set up you need two subs, but it must be a big room. people saying two
sub will sound better, but another
said with a good sub will be better than two regular. i haven't tried it yet
, but i don't think i will invest another

现在只连A A 听著更原来差不多
只练B B声音很微小
这是什么原因？ |

发帖数: 3139 | 12 谁知道箱子怎么设计的，看看说明书呗。。。看看B是不是专门的Bi-amping
connectors，可能有lowpass什么的，或者需要Z型或者II型jump。 |

发帖数: 421 | 13 提到biamp， 是不是需要再买个一样的后级才会有效果。 我现在的后级是2声道，每声
道100w。 我看到后面有High L, Low L High R, Low R. 用双线连接 和单线连会有区
别嘛？因为我的线都是埋墙里了，每声道就埋了一根线。 所以我只是用了后级的High
R， high L输出， 然后spealer上用自带的跳线把high 和low连起来了。所以没试过
biwiring 和biamping。

发帖数: 2719 | 16 yes.. that will work. That's a poor-man's bi-amping. bi-amping, in its pure
form is having 2 sperate amps.
Bi-wiring is connecting 2 sets of speaker wires from the same speaker outlet
.
the poor-man's bi-amping is still from the same amp, but 2 different speaker
outlets. There will no significant imporvement, as it is still from the
same receiever, the same power supply and etc. But give it a try if you have
an extra set of speakers wires already. I would not bother if you still
have to purchase... 阅读全帖 |

发帖数: 672 | 17 just got an idea, since playing speaker set A+B will likely to drop the
power from 120 to 60W, then I can just set the HK3490 to play A+B and only
use one set of HK3490's speaker outlet. In that case their power will be
very close. Now I'm only worried about that aforementioned connection scheme. |

发帖数: 2719 | 18 when doing bi-amping, both amp must be of the same brand, model and spec.
amps from different brands, all have different impedences. Same level of
outputs to different amps would sound very different. There is also timing
difference.
i don;t think you can do what you were describing...

发帖数: 672 | 20 昨晚上换上国内买来的秋叶原的LB5108喇叭线后发现一个现象，听完了关功放的时候，
也就是用遥控器上的Off让其处于standby，右侧的音箱会明显的pop一声。原来用16
gauge biwire的时候，关机没有这个声音。新线到手后，把原来的16gauge裁了两节做
jumper wire了。新线确实把音质提高了很多，huge difference! 声音清晰，空间感好
了很多，就是不知道这个破音的现象是否值得注意，要是对喇叭损害不大，也就不介意
了。 |

发帖数: 672 | 21 这个之前买回家听过，一前一直用Bose901 想换换BW家的书架箱听听。当时的配置就是
685 + HK3490功放。Biwire 一下效果还是蛮不错的，尤其是高音非常的bright，刚开
始有点不习惯。他的port 是front fire的，可以靠墙很近放，低音很重。650一对，好
像是得了奖的设计，真的很不错。最好用好点的线。我从淘宝上买了一对秋叶原的
Lb5108，比起Amazon上买来的16gauge真是天壤之别。功放不妨试试Marantz的Pm6004，
网上的review看着不错。两个加起来不到1500。不差钱的话audiogon 上有一对Marantz
PM15S2+SA5S2 要2800,我在BB的showroom里听过，这个被配置推686，然后听上万的
Mcintosh推802D觉得不知道那几万花到哪儿了 |

我觉得很难对比。。。。
用的是他店里最贵的唱机是VPI的，2-3千吧，喇叭是Monitor Audio的 GX50。
听得是jazz, piano 和一点小提琴，音场很大，高音清脆的很，这跟喇叭也有关，我之
前听过这对GX50， 我觉得比我的debut carbon+2m Bronze+ B&W CM5 biwired效果差不
多。我买2MBronze的主要原因是换着好换，和原配2M Red一样重量和尺寸。单说声音这
俩真的差别不大，差50块钱的东西，我的耳朵是去分不开的。和2M Red比起来差别很大
，尤其是noise floor, 有的盘基本上听不到爆豆子的声音了。
目前我觉得唱机的音场和数字音乐的比起来缺乏一点景深，感觉音场左右差不多大，但
是instrument前后的separation有限，但是动态范围和高音感觉唱机更占优势。 |
