聆听麦景图MA6300+JBL

gzwpf

看了MA6300的资料介绍，一直没机会现场聆听，（总不好意思骗买家）一个朋友想购买一套5万元的系统，终于有了机会，起码是个借口。去了海印，先听了MA6300与意大利的某个箱子（抱歉记不住型号）感觉真的很好，特别是高音，像绢般柔滑。让人联想到女人的脊背（想歪了），但由于喇叭口径小，低音稍差。然后又去听了搭配JBL
绝配，毕竟都是美国出生的，天生一对。无可挑剔。特别是听腾格尔《天堂》发烧友总说腾格尔很难伺候的。特别是：我爱你的“爱”很多系统都会失控了，但麦景图由于采用了Power Guide电路，当有突然的大失真时，会自动降低输入电平，虽然此时可能不保真了，但且在可控的范围，我想，这也许就是“保真的好听”吧。佩服麦景图啊，后来从网上搜索此机的资料，发现变压器不是大块头，滤波电容只有两个，散热片也很小。机箱内部很空荡。佩服至极，可见好听不论块头。

麦景图MA6300?不是最低的就是6500吗？

大家都说飞线不好，可搁在名牌机器里，大家反而不去计较了？

6900才是MC的起步
