w數只供參考,加埋前級增益已改變好大,例如audio research前級增益攞得好盡,單講以前用audio note m1及audio ...

What you talking is another topic: System Gain.
And system gain do change the sound louder or not, and change the damping higher or not, but do not really change the power amp driving ability.

所以話部機幾多輸出,好唔好力數字上只供參考,100w好唔好力,剩係部合併機前級份料已經影響咗,所以好唔好力,真係無一個標準答案
小弟以前部UNISON RESEARCH ,大家都係EL34,4支EL34 3支12AX7,五極35W AB類,三極36W A類,6支EL34,2支12AX7,一部開9點,一部要開到10點半,當然音色另計,其中原因一部用無源前級,一部多咗支胆做增益
另有C兄話啫,我未聽過MA6600 VS MA7000,200W VS 250W,但聽感輸出相差一倍,有機會都想聽下
所以都係耳聽為實,再唔係抬部機落去試,我買ATC喇叭嗰陣都係抬部機去試,推得掂先買,當然CDP個動態輸出db又會影響個音壓

單以100W@ 8ohms數據來說,要睇是屬那類Amp。
1. Class B : No
2. Class AB : So so. ...

How about Atoll 100se, show out spec as 100w per channel, but no damping factor show out???
Thank you

仲有大家要搞清楚,好多機包括數萬元級來路名牌,根本什少真正 pure class A,響 8 ohms 負載 1KHz 狀態下標稱為 pure class A o既就多的是。
真正 pure class A 係非常恐佈 o既事,因為大家冇一定電子底,我好難解釋,總之如果要做一部基本全頻合理負載阻抗範圍內(20Hz -20KHz,3 ohms - 16O ohms)都係真正 pure class A o既 100W 後級,有人抬十皮野 cash 比我訂做我都 say no。

Hi, Wilmer,
Is it the case that only power amp has class A, A/B, B, D, etctype, but not pre-amp?
