| [#2] 後級唔熱唔好聲,True or NOT??? wrong assumption nuforce class d amps very good design and sound better than a lot of class a amps. new mark levinson 5xx amps very nice too. just warm not hot. it is a waste of electricity turning into heat instead of power. 最後修改時間: 2011-06-25 12:59:00 |

| [#3] 後級唔熱唔好聲,True or NOT??? 你夏天唔開冷氣仲好聲，火燭都有你份，其實熱唔熱睇效益，中學物理都有教，energy lost ma. ^_^ |

| [#9] 後級唔熱唔好聲,True or NOT??? 但太熱聽耐變淋聲. that means there are inferior electronic components inside. a well designed circuit and well chosen components will not do this. |

| [#11] 後級唔熱唔好聲,True or NOT??? According to Nelson Pass: I set the bias to 50 degrees Celcius after the power amp has been running for a few hours. How to check for 50 degrees Celcius? My hand can keep touching the heatsink for 10 seconds.  |

| [#12] 後級唔熱唔好聲,True or NOT??? """My hand can keep touching the heatsink for 10 seconds.""" this is stupid using your hand. u can only "measure" the cover not the temperature inside, not the actual temperature of the transformer, capacitors, circuit board. i dont believe nelson pass actually said that. 最後修改時間: 2011-06-26 11:01:09 |

| [#14] 後級唔熱唔好聲,True or NOT??? "i dont believe nelson pass actually said that." The proof is here: http://www.diyaudio.com/forums/pass-labs/55067-usher-amps-just-lookalike-buildt-licence-6.html "I would set the bias so that after a couple hours operation the heat sink temperature settles into 50 deg C (ten second hand-on-sink test)" --- Nelson Pass |

| [#15] 後級唔熱唔好聲,True or NOT??? For Solid State Amplifier, i personally prefer Class AB amplifer design. They are generally warm rather than hot. Class A could sound great in many circumstances, but they are really hot and not energy efficient. I believe they serve well with most popular music pieces. At the extreme, they may not be as powerful as Class AB (of the same price range) to deal with music that demand large dynamic range. |

| [#16] 後級唔熱唔好聲,True or NOT??? that nelson pass quote was referring to usher 1.5 and he put a smiley after the quote meaning it is supposed not to be taken as the norm. not all pass amplifiers measure with temp of heat sinks at 50 degrees c. |

| [#18] 後級唔熱唔好聲,True or NOT??? My current poweramp can be switched btw class A/B, & class A operation which draw 1,000 watts from the mains even when idle!! To my humble ears the sound is notably more dimensional & bass better layered when run in class A, of course it gets pretty hot that way. |

| [#20] 後級唔熱唔好聲,True or NOT??? as per your post #11 """According to Nelson Pass: I set the bias to 50 degrees Celcius after the power amp has been running for a few hours.""" actual post from nelson pass was "I would set ...." and it was referring not to his products as a norm. I set and I would set have different meanings. |
