原文如下:(不代表本人看法)
![]() ![]() ![]() http://www.roger-russell.com/wire/wire.htm 作者Roger Rusell是Formerly Director of Acoustic Research at McIntosh Laboratory, Inc. 原文较长,节选部分原文 Several speaker wire manufacturers make wire that has high capacitance yet almost none of them publish exactly what the capacitance actually is. Capacitance is of concern not so much that it could cause a possible high frequency rolloff but that it can affect the amplifier feedback and cause the leading edge of transients to overshoot. This in turn can make an audible difference in the system sound. It can make the sound brighter, which some audiophiles mistake as greater detail. The degree of influence when using high capacitance wire depends on three factors. 1. The total capacitance of the wire used (capacitance per foot times the number of feet). 2. The complex impedance of the speaker being used. 3. The stability of the amplifier being used to drive the speaker. When there is an audible difference in speaker wire due to wire capacitance, it can be interpreted as an improvement when one wire appears to have more clarity but is actually altering the sound and departing from accuracy. Perhaps this change in sound then paves the way to sell more wire. Further, perhaps the wire companies already know this and what will sell. 喇叭线对声音的影响取决于线材的电容,喇叭的综合内阻和功放的稳定性。有些喇叭线故意设计成具有高内阻值,有可能会听上去更明亮一些,但是那是失真的表现,却可能被认为是听到了更多的细节。而且一台设计良好性能稳定的功放,是很少会受到线材电容带来的影响。只有那些稳定性较差的功放才可能会带来显著的影响。 Many owners of high-end audio and video equipment value “oxygen free” copper. Behind this demand is the belief that it will have enhanced conductivity or other electrical properties that are significantly advantageous to audio signal transmission. However, as indicated above, most C11000 common copper sold today meets or exceeds the 101% IACS conductivity and overlaps C10200 “oxygen free” that has a minimum of 100% IACS conductivity. In practice, there is no significant difference in conductivity between all three of the grades as far as audio use is concerned. It can be solid, stranded, copper, oxygen free copper, silver, etc.--or even "magic" wire--as long as the resistance is kept to be less than 5% of the speaker impedance. There is no listening difference as long as the wire is of adequate size. Bear in mind, as previously mentioned, a well-designed amplifier will not have a problem with any of these wires. 符合国际标准纯度的铜对于音质的影响是很小的,甚至最普通的C 10200(仅3N纯度)的铜就足够满足音响设备的需求。对于设计良好的功放而言,只要线材的阻抗不超过喇叭内阻的5%,是不会带来明显的听觉差异。 银线的导电性虽好于铜线,但是并无法带来声音的提升。 Looking at this from a different perspective, there will always be those who will want expensive wire, not because there is an audible difference, but because they may value pride of ownership and prestige in a similar way to that of owning a Tiffany lamp or a Rolex watch. 其他部分对线材的垫材,煲线器他都认为属于是this is just another way of making money. It can be considered as another “quack” remedy machine. 其中还有一个链接分析了功放阻尼系数的问题,那是Damping, Damping Factor, and Damn Nonsense |

sz517 发表于 2013-7-31 12:32 “非一千万不听”。这就是你甫一登场的惊人亮相。谁都知道那说的是公共设备根本不是家用音响,惟其如此,你这打肿脸充胖子哗众取宠的浅薄小市民,伪hifi烧友,才让我鄙视。人品学风都有问题。说第一回也就算了,没人跟你计较,你还尾巴越翘越高,其实连甲类功放都没摸过,也大谈特谈有源无源之优劣,谈不出所以然就再拿“国家大剧院”“太庙三高演唱会”来当虎皮吓人。再吓不住人就开始骂街撒泼。瞧瞧你那屌丝德行,大概是卑微惯了,等不及想给自己加道光环,没成功,就凶相毕露。你真衰到家。继续去百度捡砖头砌楼吧。也就剩下这本事。 |

sz517 发表于 2013-7-31 12:32 非常赞同。 剩下的问题是,如何面对这类伪装的大湿,通常这类大湿比普通烧友多懂点电声知识的,一般烧友还是辩不过他们,只有靠正真的技术男来不断地质疑他们。 |

各位,穷有穷玩,富有富玩,一套HiFi上百万了,买个10来万的线也没什么。
我不排斥好线,但我量力而行。不会盲目追求顶级。。 一套3W的HiFi和30W的声音上会区别很大。。 但一套30W的和300W的区别几乎是微乎其微的。。看怎么追求了,极致永远没头的。。 理性发烧和盲目发骚完全不同。。哈哈 ![]() |

听HIFI本来就是让人享受美妙的乐感,但极端的烧器材就让人变成无节制地烧钱。HIFI器材就象汽车一样,想跑出极速需要很多条件,想换条好胎就想让车子跑出好成绩,远不如上条好的赛道来得实际。而且人的素质有差异,就是让你开F1也比不上舒马赫开皇冠快,听HIFI器材也一样。购HIFI器材在自己预算内达到自己最佳效果就好,否则就是为炫耀而烧钱,无聊至极。

我发现那些大牌的音响厂家都没什么技术,你看人家一根线材就能解决的问题,你要花这么多功夫来解决!

其实发烧线的影响没多大,如果能从音响结构上改进影响更大。比如大部分音响的输出是单端的,各个单元根本之间无法实现单点接地。而不够好的接地,对音质的影响比线材的影响要大几个量级以上,而且这个是可以听出来的。在比较敏感的电路里,电路讲究的是体积要小,如果做不到小,各个单元连线是要用差分的,音响里面应该是平衡的。但这样其实还不够,要想好,各个单元都要是平衡的,包括功放。不过我观察到的功放除了BTL的都是单端输出的,即使BTL的也只是伪差分的结构,真正平衡的电路,我还没见过。各种所谓高端,也仅仅是吧当前的电路发挥的更接近原始电路图(寄生电阻更小而已),可能是因为人耳的分辨率有限吧,高级的电路结构没有必要。
