其實int amp 100w RMS /8 omh 算唔算好力呢?

Damping factor 會吾會係log scale咁上架呢？要加個零先係下一級

It should be a ratio of something as I remember, but I forgot the details. I heard that damping factor over 200 is already quite good for class A/B power amps.

I am waiting for master Wilmer's explanation!!

Nuforce said there is no meaning of damping factor for its power amps because of its special design, which I still could not understand why. But if what Nuforce said is true, damping factor might only apply to certain groups of amps.

無得知，靠試，因為喇叭廠唔會比哂所有 SPEC 你睇。

Thanks a lot for Wilmer's explanations.

I think I have to do more research myself and take some time to learn some circuits theory in the future.

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 research sp9兩部前級推同一部後級,m1要開到11點先夠聲,sp9開到8點半已經夠聲
