| [#94] 平衡好聲還是非平衡好聲 理論上真平衡是比較好，但設計和製造上比非平衡困難多倍以上，當然成本和售價不能討好消費者啦；所以好多廠只有加假平衡便算數，始終也是非平衡的音質。 |

| [#93] 平衡好聲還是非平衡好聲 因爲要配合XLR呢個風潮，好多廠廠商都要響設計上邊作改動，需要在輸入級加多一級放大電路（Instrumentation amp - Op amp）去作RCA和XLR轉換。 但係其實內部線路根本佢都唔係走正負信號獨立放大，就好似金xx噉樣（e.g. A系列）。 咁樣究竟係多咗一級Op amp線路會令到世界更美好，定係多隻香爐多隻鬼呢。 我諗廠商先至更加清楚，又或者佢啲擁躉。從最早嗰啲model玩到而家新線路，可能佢哋就最明白個音色變化喺邊度，全面變好，有失有得啊，定係其他。 最後修改時間: 2019-09-01 07:00:25 |

| [#91] 平衡好聲還是非平衡好聲 其實呢個純粹商業行為，冇新嘢就唔會刺激到消費。 將一個遠距離傳輸防噪音嘅技術用在短距離，自己諗下合唔合理。 將一份擴音機，夾硬將佢分成兩份。又要佢哋完全放大到一模一樣。相位、頻寬、幅度和時間差都不能有分別，合唔合理。（其實放大器PCB板上面有N咁多粒零件，大把嘅電容。大家衰減程度都不一致，可唔可以長時間維持完全一樣，好成疑問?） 到時可能噪音就消滅咗，但係因為兩塊板放大程度和電源噪音不一樣就產生咗其他嘅問題出嚟。 都係simple is the best。 最後修改時間: 2019-09-01 01:07:23 |

| [#87] 平衡好聲還是非平衡好聲 I have been quite fortunate that starting from my 2nd set of pre-amp/amp. everything was balanced circuited. And 10+++ years ago, starting from Laser disc player, CDP, Pre-amp, power amp, they all set up vertically in a stack stand arrangement. I could not stand the noises from RCA cables because the cables at the back of the stand were messy. Each RCA cable picked up a lot of noises. So I have eliminated RCA cables from my system. Even my laser disc/DVD/blu-ray I used optical or AES to connect to my CDP/DAC so that I isolated noises away from TV. The only RCA cable system that I have auditioned was the mightly CAT SL-1 + CAT JL-2. They used a 3 meter pair of RCA cables from pre-amp to amp, and I could not hear any trace of noises. Of course, if the system is tube amp and/or with turntable then it does not matter because they are noisy anway --- I love tube amp + turntable --- but it does not mean I like noises. |

| [#86] 平衡好聲還是非平衡好聲 I have listened to quite a few balanced systems. My current chain with digital source is capable of truly balanced operation from CD player to preamp to power amp. My conclusion is that it is not automatic that balanced operation must be better. As commented by various fellow posters, balanced implementations involve more components (actually incuring longer signal paths than similar single ended designs) and tighter component matching. If not implemented well, it would do more harm than good, especially in situation where the advantages of balanced connection may not be needed, such as short cable run over a (electronically) clean area. |

| [#84] 平衡好聲還是非平衡好聲 平衡代表多一組線路，如果你訊號線不太長，用平衡不單不能減少 noise，反而因多一組線路而多左隻鬼。 |

| [#83] 平衡好聲還是非平衡好聲 其实平衡相对于非平衡唯一可见的优点就是平衡的远距离传输(2M以上)失真相对小,仅此而已,其他的不同只是特点而不一定是优点,特点也可以是缺点.毒药与蜜糖其实并无明显分界,关键在于你如何用. 音响最重要的不是价钱,不是胆或石,不是电路的结构如何,不是数据如何靓仔,甚至不是电子元件的好坏(当然,这些都重要,但不是最),最重要的是搭配.当你套系统玩得足够好足够平衡的话,三粒机垫钉的改变已经可以令你套系统由吾想熄机变成吾想开机,但当你改变钉垫的同时换条信号线,或者你套系统又可以立即起死回生.音响之所以好玩就在于此--无法解释的奇妙. 所以你可以讲一套系统好仲系吾好,但不能讲一台机或一条线好仲系吾好,因为系统系搭出来既,而机系要罗去搭既,搭得好就甘就好罗. 又所以:一百万既系统一定比三两万既好声?不一定.立体声音响发展到今时今日,其实早就已经走到尽,而家不过系一个大口要价卖噱头的年代,够胆卖甘贵而已. 翻番主题:平衡同非平衡一样可以好声,问题在于你点搭. 另外:有朋友罗列数据话如何如何,其实,人耳系好蠢既,好多野听吾到,即使听得到都未必系好事,听多左同好听系两回事.若果论数据,边有机好得过日本机?但到底有几多人喜欢听日本声? 所以:价钱系呃人既,数据系呃人既,但有一样野吾会呃你:你自己对耳.当然,你要先学识去听. |

| [#82] 平衡好聲還是非平衡好聲 在我黎講,你亦係我前輩,因為你呢方面ｇａ知識比我多好多,唔通你又係無去學新野咩? 我所以咁講係因為。個位前輩話佢自己都曾經多年來都以訛傳訛,話xlr好過rca,但佢話事實勝於雄辯,很容易可以比較出來 |

| [#80] 平衡好聲還是非平衡好聲 Sowk: “Balance: Benefit or Bluff? By Martin Colloms " November, 1994 http://www.stereophile.com/features/335/ " This is a good article. Thanks sowk for the referral. Basically I agree with Martin Colloms that although balanced operation has technological advantages, in practice it doesn’t automatically translate to better musical enjoyment of an audio system. This is especially true in those earlier days (when Colloms wrote the article) when balanced operations were not as well implemented as some of today’s hi-end equipments. Although I use balanced connections mostly, I still use single ended in some places. Direct listening is my ultimate judge. The sure way (to me) to know if an equipment is truly balanced is by examining the circuit schematics, which is often not available. Possibly by looking the components layout, one may be able tell. Normally, a true balanced circuit is like 2 symmetrical single-ended halves. For example, in a preamp, there should be 2 volume control VR’s per channel (one for each phase of a channel), so there should be 4 volume control VR’s in a stereo preamp. |

| [#79] 平衡好聲還是非平衡好聲 如果咁測試法,出黎既結果,係代表線/AMP/CD PLAYER既RCA/XLR 表現好D呢?? 如我之前所講(當真平衡計,撇除假平衡因數) 1.CD PLAYER 既 RCA/XLR那一面好聲D = 唔知 2.AMP 既 RCA/XLR 那一面好聲D = 唔知 (如果用前後級重死又多一個未知數) 3.線 (同一品牌同一型號) 既 RCA/XLR 那一面好聲D = 唔知 咁多未知既數一起互動,點可得出一個準確既答案呢?? |

| [#78] 平衡好聲還是非平衡好聲 Just an idea. To test if they are balance or not. Use both XLR and RCA cables at different time to see if there is an obvious gain of sound level from the XLR, provided that the CD player has a true balance output. |
