后级越大power越好？？？

以前我以为power amp越大watt，咁就唔使扭咁大volume，咁如果我听人声咁就冇问题，相信好多人同我一知半解嘅人都问过其
他人究竟power越大，咁乜好，佢地就话会把你喇叭推得更好……
咁即係有几好？？？？直至我入咗三部后级玩av，就试300w推每边f12同bridge咗佢1000w推，音量其实冇乜点变，唔会你大力d，volume掣可以扭细d，而係分别就係高中低音都推得伸延更好，就好似一个人唱歌，唔识用丹田同识用丹田唱出嚟嘅分别一样。好似我朋友对dyna，佢power amp係细火数，但果次去听係有声出，但只觉得高低唔似之前用onkyo av amp推得咁好一样。因dyna係座地，av amp都有150w，但而家佢只用低於100w去推。

AV amp 內置份poweramp 同正式power相差甚遠 不能咁比

件AMP質數好重要，去聴吓金仔部E-560，得30W

my vintage 2-ch power-amp is only giving 45w per channel but it is already giving so much detail and much more detail than my av-amp which claims to be much more powerful than my power-amp.

i now switched to biamping (with 2 identical power-amps, one driving tweeters and one the woofers), suddenly more detail arise and better imaging too.

i wont simply say higher power is better, but the design is more important.

佢好似話部AV amp有150W 推得好靚聲

好過現在的所謂 100W power amp................請細心睇清楚樓主講嘜

現時的AV amp的power大多作大，報single channel driven 及output at 6 ohm。但開5聲道時其音5折都冇。Power amp 是要電流及控制力，不能只大瓦數
