[#1] Amp Damping 點睇好唔好? 我果部係 >110 8 ohm, 咩數值係好呢? |

[#2] Amp Damping 點睇好唔好? It's enough for most speakers except the most difficult to drive ones. High damping factor usually result in harsher sound. Tube amps usually have low damping factor, like that value. |

[#3] Amp Damping 點睇好唔好? 我 check 過我以往用過D Amp 嘅 Damping 數值, 點先叫好呢? NAD 317 >200 Roksan KA1 Mk3 >110 Creek 5350se >160 Creek Destiny >235 NAD c355bee >160 |

[#4] Amp Damping 點睇好唔好? 唔好太信D數字呀師兄!有時太勁又會damp 死對speaker, 所以器材要夾同匹配。 |

[#5] Amp Damping 點睇好唔好? You can't tell how the amp would sound by damping factor alone. Just listen by your ears. |

[#6] Amp Damping 點睇好唔好? High damping factor means better control over speaker movement => less speaker-amplifier interaction. The caveat is that damping factor spec is typically quoted using the resistive portion of impedance so it does not give you the whole picture. |

[#7] Amp Damping 點睇好唔好? German product preform highest damping factor, like Audionet from 1000 to 10000, extremely powerful in handing speaker. |

[#8] Amp Damping 點睇好唔好? 純碎學下點睇D數字, 當然會用耳去聽啦, 咁大數值定小數值先係 good damping? NAD 317 >200 Roksan KA1 Mk3 >110 Creek 5350se >160 Creek Destiny >235 NAD c355bee >160 |

[#9] Amp Damping 點睇好唔好? Larger the number, the higher the damping. And usually when damping is >=500, the sound is pretty "hard". For most speakers, damping factor 80 is enough. Amps usually sound more musical with smaller damping factor. 最後修改時間: 2012-06-07 13:43:24 |

[#10] Amp Damping 點睇好唔好? Amps having damping factor of 100 to 200 are normal, and figures of 300 to 500 are high enough. There are amps having extremely high damping factor like 2000, by using very high negative feedback, these amps will never sound good. damping factor = speaker impedance/output impedance of amp |

[#11] Amp Damping 點睇好唔好? 明白哂,反而我覺得 roksan 個 damping 數字最細 >110, 控制力仲好過其他大過佢,真係要用耳聽! |

[#14] Amp Damping 點睇好唔好? My Burmester 082 damping is larger than 1000. Sound real and great than my previous amp like Jeff Rowland Continumn 500 and Goldmund 330. 推Thiel CS7 爆到飛起,100w的082wins 500w的JF 500很多! 最後修改時間: 2012-06-07 19:57:12 |

[#19] Amp Damping 點睇好唔好? """Like most specifications, damping factor does not tell you an amplifier is "good". It can't; no more than a tuner with a great image rejection specification is guaranteed to be a "good tuner". There is a lot more to good amplifier performance than output impedance. Frequency response, mentioned previously, is a good example; suppose the amplifier had a damping factor of 10,000 at 8 ohms, a stunning number (because it implies a very, very low output impedance)... but could only reproduce frequencies between 300 Hz and 1 KHz? Your music would sound pretty awful. Another is distortion: Suppose the amplifier distorts the music? What good is it then to have the speaker do more (even just slightly more) precisely what the amplifier says? Not much! So don't let damping factor go to your head, so to speak - it's one of many specs, one where higher numbers are better because they tell you that the amplifier has a lower output impedance, which is good. Read all the specs, try to learn what they all mean, and then you'll be able to get a good picture of amplifier performance. The bottom line is, a really low damping factor can tell you an amp isn't going to be all that great with a highly reactive speaker (the larger a speaker driver is physically, and the more power it is designed to handle, the more likely it is to be highly reactive.) What's really low? Well, if we're talking about 8 ohm speakers, a damping factor below about 30 indicates it's going to have noticeably poorer control of a highly reactive load as compared to an amplifier with a damping factor of 100. How much? It works out to about 10% worse (because you have to factor in the speaker resistance.) As the damping factor goes lower, it gets worse yet. You can hear a 10% difference in speaker control. Trust me! """ http://www.classic-audio.com/marantz/mdampingfactor.html |

[#20] Amp Damping 點睇好唔好? cpu, you wrote: "You can hear a 10% difference in speaker control. Trust me!". How on earth can you manage that, do your ears are also some kind of instruments which can quantitatively measure this 10% difference in speaker control??? 最後修改時間: 2012-06-07 23:16:55 |
