Update:
我把这个胆Buffer挪到了楼上的小型Denon系统上, 效果竟然意想不到的好, 声音温暖丰富, 连续听几个小时都不觉得累. 连家里不发烧的人类都称赞声音好. 归纳原因, 1是褒了一个星期管子已经开发了, 2是在低价系统上的表现要大大好于高档功放系统. 后来找到了官网上的一段话,验证了我的猜测.
Who the B-283 MKII isn't for:
Audiophiles with a $20k plus audio system. You have already paid good money for what the B-283 MKII will do for lesser systems. Our tests have indicated that on true audiophile systems the results are very subtle to be noticeable, which is actually a good indication of how good the B-283 MKII is. If you are an audiophile and want great tube sound, check out our Grant Fidelity tube amps.
我现在非常喜欢这个小胆, 并推荐低烧人群尝试.
