| [#2] 建唔建議部Amp及CDP長開? 如果長開, Amp是否要細細聲開住啲音樂(如radio)? (何解?) CDP standby mode 可以嗎？ 最後修改時間: 2010-03-10 08:57:13 |

| [#3] 建唔建議部Amp及CDP長開? preamp - yes, especially tube preamps, so you won't have to wait to get it warm up. In fact, I used to have a tube preamp which was designed to be left powered on 24x7. power amp - I would not as there was too much heat built up. CDP - of course no problem leaving it in standby. In case of leaving it totally on, some said that in some player, the laser was active even when not playing, in which case leaving on 24x7 may not be a good idea. Leaving electronics on 24x7 not only keeps them in their best sounding state but also extend the their lives as typically, electrical failures are caused by repeated power surges at turn-on. Of course, you should only leave good quality electronic equipment with UL or CSA certification on 24x7 (or even standby) because you may be running the risk of electrical fire/heat problem for unknown quality products. Also, if you are an environmentalist (or if you are living with one) or if you are someone who always follows what the government told you to do, then I would not suggest you to take such wasteful/radical/risky actions. |

| [#5] 建唔建議部Amp及CDP長開? For speaker, it's good to maintain operate. For Amp, specically high RH season....Keep power on is good. |

| [#6] 建唔建議部Amp及CDP長開? 石机壞前級可以長開，有些前級是沒開關的。 後級就不用，15分鐘已進入狀態。 CDP 也—可 長在standby mode 最後修改時間: 2010-03-11 09:52:21 |

| [#9] 建唔建議部Amp及CDP長開? Standby is ok, keep on 24 hours only make the parts inside get "old" very quickly, you'll shorten its life eventually. |

| [#11] 建唔建議部Amp及CDP長開? Yes, provided they are designed for it. Some high end CDP, DAC and preamp that I used to own had this recommendation writen in the operation manuals. |

| [#13] 建唔建議部Amp及CDP長開? ＞但又有人話開機時的電流脈沖係最傷部機, 係咪真呢? Yes. In general, power-on surges are more destructive than aging through usage, particularly in low current/heat situations such as preamps. As I said before, I wouldn't leave my power amp on 24x7 due to heat built-up which would shorten the lives of the components inside. |

| [#14] 建唔建議部Amp及CDP長開? No definite answer. It all depends on the design. My CDP is always on. And for my Rowland Model7 power amp., though they are not switched on, the driving module is always powered once the power plug is connected. As long as the temperature is kept low enough, i.e. below 45°C, then the life of the electrolytic caps is OK. |

| [#15] 建唔建議部Amp及CDP長開? 故事分享.... 從前有一個好天真的小朋友, 買左一部PRE-AMP, 美國制,某一線highend 大廠出品 (人名來的, 2個字 M字頭, N尾) 說明書, 話佢部pre amp 每小時耗電量少過一粒15w 燈泡, 唔會發出高溫, 絕對安全, 而且部機得個STANDBY 冇開機制, 睇DESIGN 又完全冇諗過要熄機喎.....咁小朋友就聽佢講, 就長開唔熄喇............ 幸褔快樂既日子通常過得特別快.....如時者過左幾年, 某日,"拍拍數聲, 一陣輕煙, 香味四散",一部就成為一舊15kg 的廢鐵............好彩當時有人係屋企, 及時熄機, 否則果不明..... 之後小朋友帶部機去代理, 代理醫生話火牛原廠要HKD 2.5K, 其他零件, 手術費另計喎..... 咁小朋友就比間廠欺騙左.....從此冇再買呢個一線大廠的野, 亦唔再相信電器係唔駛熄的 故事分享完畢, 謝謝. |

| [#17] 建唔建議部Amp及CDP長開? to have equipment on 24x7 u need very good power stabilizer and surge protection. if voltage not stabilized it may shorten life of components. power surge will burn up everything especially during thunderstorm. future: that young man has no understanding the quality of electricity. it is not the fault of the equipment manufacturer who would have assumed clean power. some states in the us are using very old electrical generators and discrepancies can be as high as + or -20%. |

| [#18] 建唔建議部Amp及CDP長開? 我就唔建議長開,通左電就當standby mode,我就習慣細細聲開機之後去冲個靚涼,大約半個鍾後咪坐低慢慢聽,如A類點長開. |
