回复:LP的背景交流声问题

首先把唱放的输入端悬空(不接唱盘)试试,因为我曾接触过一款欧博的唱放本身存在交流声。
其次,由于唱臂自身没有独立的地线,那就要检测是否有接地不良或者重复接地的现象。

Graham Slee 还有一款唱放叫 Gram Amp 2 SE(特别版),得到的好评更是吓人,列出来吓人一大跳。计有:

总结起来,就是曾经被美国 Stereophile “立体声”杂志六次列入推荐榜单,被绝对LL的 The Absolute Sound “绝对音响”杂志两次推荐为 Best Buy,另两次是获得级别最高的“编辑推荐 Best Buy”。

"...all the earmarks of a giant killer...the more you listen to this thing on its own, the more you’ll discover that you can play it for hours without fatigue...the presentation had a rare top to bottom cohesiveness, with a tonal balance unusually rich, lush, and, well, beautiful...It’s love at first sound between the Gram Amp and vocalists, while violins are marvellously silken..."
Paul Seydor, Absolute Analog, The Absolute Sound, Feb/Mar 2002
(“绝对音响”的评论——罕见的从高频到低频的浑然一体,声音平衡,播放人声令人一听倾心,小提琴声音如丝绸 ...)

"...they’ll be amazed by its sound...the Gram delivered genuine solidity in the mid-band and mid-bass. It was quiet, and free from the thinness, edge, and grain you usually get at this price..."
"...I wouldn't spend the difference between the Gram and the Dino if I were going to use it solely for MM amplification... I'd be paying for stages I wouldn't be using, and I wouldn't enjoy the sound over extended listening even with the Dino+ power supply option..."
Michael Fremer, Analog Corner, Stereophile, June 2002
(Stereophile 的评论——中频和中低频段具有真正的密度,背景宁静,毫无这个价位产品常见的瘦硬感和沙砾感 ... )

外行说句,十有八,九是接地问题,我第一次玩LP时不懂接地,就是背景噪声,接地后马上安静
的出奇。

如果接地等等都没有问题;
把唱头到欧博PM-1唱放的信号线取下,必要的话可短路唱放的信号输入,看是否仍然有交流声?
大多数可能应该是欧博PM-1唱放的“本底噪声”。
对于音响器材来说:绝对“理想的、忠实地还原”是没有的,也是做不到的;我们只是在朝着“音响器材各自应该具备的基本性能”方面尽量努力,使其各尽其责而已。目的就是尽可能地做到“理想的、忠实地还原”。

经过测试,拔去LP输入端子后,交流声更大。但是否唱放问题还待商榷。因我还用一朗泉唱放连接过,同样有这个交流声
