[#59] Power amp 唔應該用 Power Conditioner? I would like to share my experience about using line filter. Now I used a Weiduka AC8.8 line filter, there is 2 independence line filters inside it. At the beginning, I think that it should be the same of any 13amp socket of it then plug the power amp to left hand side of the socket. The sound seems no any improvement perhaps it may be even worser. Then I plug the amp to the right hand side of socket, this time the sound had a great improvement (more detail and sharp still sweet, singer month is smaller and bass is more solid and powerful) sure I had tried it several times to confirm it (including use or not use the filter). Then I open the filter cover, what I found is that a digital voltmeter is connected to the left hand side of socket inside. Finally, I add a switch to this voltmeter and normally switched off it then the sound of my power amp is kept to have a great improvement no matter plug it to any side. So, I sure that line filter is really work on my system and the digital noise would affect the sound quality a lot specailly for the power amp without line filter inside. I am using a class A 300B tube power amp. 最後修改時間: 2015-09-20 22:51:04 |

[#58] Power amp 唔應該用 Power Conditioner? 將power amp 連到隆宇加追踪濾波器,效果很正面. |

[#57] Power amp 唔應該用 Power Conditioner? 呢D問題係冇答案嘅。因為件野係用嚟針對器材同供電環境嘅互動關係,唔同器材喺唔同供電環境下嘅組合係需要唔同嘅針對處理。 |

[#56] Power amp 唔應該用 Power Conditioner? 其實係咪要睇埋其他因素? 如水塘唔夠大,power cord就會有較大影響,如家裡有其他电器干擾电源,淨化器作用又會大d,胆机,石机效果可能不ㄧ樣? |

[#54] Power amp 唔應該用 Power Conditioner? Power generator or conditioner 都有有啲壓縮感,唔用好過。 |

[#53] Power amp 唔應該用 Power Conditioner? I think the result is very dependent on the design of the power amp and the type of power conditioner Im using ps audio p10 power regenerator It is unique because it works as a voltage regulator ( rise to 230 v), and the output impedance is 100 times lower than the power line. Im connecting the conrad johnson premier one to it and the improvement in sound is remarkable. Im not sure whether the performance will be downgraded at the peak output. |

[#48] Power amp 唔應該用 Power Conditioner? Odysseyhk hing Thks for sharing your thoughts Agree that we probably need more chings to share their Experience to get better idea Anyway, class D and switching supply for hifi is getting popular for a history of roughly 10+ years. I tend to believe there is plenty of room for development 最後修改時間: 2012-09-02 10:56:24 |

[#47] Power amp 唔應該用 Power Conditioner? faimiu, It is difficult to answer your question as audition is not a scientific measurement of a design. I suspect it is due to the fact that Class-D amp is very high power efficiency. It is much easier for the internal power supply circuit to fullfil the instantaneous power drawn by the amp. And therefore the dependancy power source responsiveness will be less. Even I have tested it ok in my environment, I suggest more C Hing here test in your environment and share if you have similar results with different combinations. My audition test is subjective and empirical, so it is not going to be conclusive. The results may be different for different brand of class-D amp and power conditioner. Need more sample to be more sure. |

[#46] Power amp 唔應該用 Power Conditioner? ODysseyhk Hing For the sake of clarification, do you think the observation is due to the Class D design, or is it related to the use of switching power supply, that may be more vulnerable to power line interferences? Thks in advance. 最後修改時間: 2012-09-02 06:22:25 |

[#44] Power amp 唔應該用 Power Conditioner? Finally I have tested the power conditioner with class D integrated amp and DAC. There is limitation in my environment that I have to use the same power bar for integrated amp and DAC. There is no compromise with the dynamics of sound. In fact, there is overall improvement in dynamics and micro dynamics. I'm pretty happy with the results. The power conditioner I use handles common mode and differential mode noise (transient and continuous noise) plus ground noise filtering and internally support 20A at 220V. That is consistent with what my customer told me that he has excellent results with STI-1000 powered by conditioner. So I think the traditional wisdom of "Power Conditioner not good for power amp" may have some exception with class D amp + filter which can handle high current. Happy if somebody want to independently review it. I worry about I may be biased as it is not a blind test. |

[#42] Power amp 唔應該用 Power Conditioner? I have no idea what exactly has happened - my guess the power conditioner performs adversely in a way, making some power supply components within the amplifier to work much harder than normal (therefore hotter) in delivering power to the amplification circuit. 最後修改時間: 2012-08-26 22:49:22 |
