| [#61] 平衡好聲還是非平衡好聲 It is not only long and short cables. Cables can pick up a lot of noises if they are placed nearby heavy-duty equipment or some other cables. Even short cables can hear noises. Even for RCA or power cords, shielding makes a difference. |

| [#62] 平衡好聲還是非平衡好聲 I agree that short cables running over noisy environment may pick up noise and can benefit from balanced connection. Indeed, ground loop hum can happen with short cables as well. On the other hand, balanced implementation has to be done well. Otherwise, it may do more harm than good. |

| [#63] 平衡好聲還是非平衡好聲 there is a thinking of separating pre amp from power amp at a further distance. thre reasoning is related to magnetic field as generated by the higher electrical properties of power amp influencing the small electrical current in/out and within the pre amp. |

| [#64] 平衡好聲還是非平衡好聲 SOLUTION, GOLDMOND 二大品牌反對平衡! 世界最貴膽機AUDIONOTE的211合拼也只有RCA,佢0的xln是牛偶合平衡,非真平衡! 他們都好聲. KRELL ,MARK, BOULDER是真平衡,也好聲! 其實好聲就好聲,與RCA/XLN冇分別!! |

| [#66] 平衡好聲還是非平衡好聲 also krell is advocating their own CAST not xlr. please do more research before posting your bold statements and misleading newbies. |

| [#68] 平衡好聲還是非平衡好聲 cpu8088, You must be a newbie! about 10 years ago, Goldmund debunked BALANCED connection!! All Goldmunds old products were fake balanced. Besides, Krell's Cast is a true balanced design . Ask some gurus 1st. |

| [#69] 平衡好聲還是非平衡好聲 呢個問題,係可以討論過世既問題,因為每部機既rca/xlr 設計上都會偏向是旦一邊好聲d,而就算有xlr都亦有分真假,而且又要睇你用咩xlr去評測,因為有時同一品牌同一型號,rca/xlr用料都有分別. 既然咁多變數,咁點可以有統一答案呢,只要你覺得rca/xlr好聲就可以了. |

| [#70] 平衡好聲還是非平衡好聲 Dear Brothers, Brothers using Balance connection please see below link for sharing: Balance: Benefit or Bluff? By Martin Colloms " November, 1994 http://www.stereophile.com/features/335/ ------------- This is never ending argument. Just take what you like. The distance of my set up is few feet in between, however, I like Balanced connection most. Cheers |

| [#71] 平衡好聲還是非平衡好聲 futiantemo u were talking about goldmund of the old. i was talking about goldmund of the recent. 肥福 made a generalized statement and it was incorrect. why dont you quote goldmund's first power amp or any other very old power amps i am sure they dont have xlr? |

| [#72] 平衡好聲還是非平衡好聲 futiantemo """Besides, Krell's Cast is a true balanced design """ krell cast is proprietary (Current Audio Signal Transmission) circuitry which utilizes current gain topologies allowing the signal to remain in the current domain from input to output. Keeping signals in the current domain avoids unnecessary current to voltage conversions that add distortion, require heavy feedback and severely limit bandwidth. the so called true balanced xlr is voltage driven and fundamentally different from cast. |

| [#74] 平衡好聲還是非平衡好聲 If someone want to expreience the different with high frequency (20kHz) , and without high frequency (＜16kHz), just find a soundwave editor and try to cut off the high, and you will see the difference is HUGE.! |

| [#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. |

| [#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?? |

| [#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. |
