电流与功率本来就是一个关系问题。 |
也不一定的，你看金嗓子的A50、A60（输出功率分别为50瓦、60瓦）后级的电流大还是国产100瓦后级的电流大？丹拿就是吃这一套！
另外，KRELL的400X的声音比300IL更有魅力，请楼主耐心比较。
最后，SIM的P3、W3跟WANGJ的音乐之旅根本不在同一个档次，比较没意义啊！除非用W5吧！：） |
为啥不再一个档次阿？
在欧元升值钱，价格是SIM高，升值后价格差不多。
音乐之旅是120WX2，介绍：ＡＷ１２０ ＤＭＢ功率放大器是以ＡＷ１８０Ｍ为蓝本而设计的。功放的电源部分采用了两个６５０ＶＡ的环型变压器和１５０，０００ｕＦ的电容，同样亦采用了ＦＴＴ电源电路，所以能驱动极低阻抗的负载，最低竟可达到０．５Ω。 ＦＴＴ电源技术（动态变压器技术），能够提供比额定功率下大两倍的电流。因为采用了第一流的电路设计和极富功力的整机结构安排，所以其绝不妥协的设计造就出其绝不妥协的声音。
SIM也是120WX2，A "no overall feedback" design resulting in real-time amplification, a more accurate musical reproduction with respect to tonality, virtually non-existent intermodulation distortion and the elimination of common phase errors resulting from feedback · An oversized power supply · A custom proprietary toroidal transformer design with lower magnetic, electrical and thermal loss, yielding an improved power transfer and lower regulation factor, resulting in increased current speed and better dynamics · Fully balanced circuitry up to the output stage · Stable to any known speaker impedance · "Class A" output to 5 watts for greater efficiency · Precision matched Bipolar output devices which offer superb linearity throughout the entire audio frequency spectrum · A high damping factor which yields superior musical dynamics, improved signal speed and refined timbre accuracy · Extremely rigid chassis construction to minimize the effects of external vibrations · Accurate matching of the very finest high quality electronic components · A very short signal path for a faster transient response · A symmetrical circuit design · Pure copper circuit board tracings with extremely low impedance characteristics · Designed to be powered up at all times for optimal performance · Low operating temperature for a longer than normal life expectancy.
