惊雷/MOON W-3 HiFi 纯后级功放-后级功放

◆阿钟音响◆ 加拿大惊雷/MOON W-3 HiFi 纯后级功放

simaudio w-3 双声道后级的指标是8欧 120瓦，4欧 240瓦， 2欧 400瓦。属于大电流后级，阻尼系数800，桥接后400瓦单声道输出，算是典型的 hifi 后级，
很少有后级列出2欧时的功率，可见 w-3的推力和电流是比较大的。我试了用来桥接推Revel voice,对比了 bi-amp 推。

综合感觉还是桥接后推得更到位,可能归功于400瓦的功率.bi-amp 声音感觉更细腻，但是好像没推到位。
最近用下来, 感觉voice的分析力惊人,所有的细节清清楚楚传到你的耳中, 即便音量较小时,对白也听得非常清楚, 声音很有穿透力,但又不会有压迫感.

考虑到中置承担了影院中大部分的任务,这个voice带来的影院效果提升是非常明显的,当然后级必须足够给力.
