hdx + pt + Prism Sound 8XR + 10m原子时钟,我赞同,
然后补充一点,,,
就是10m原子钟是要接时钟发生器的,10m只是铷原子的发生器
Gear上有老外说过
‘’The crystal oscillator used to probe the rubidium cell is
top rate. It has to be because if it had significant jitter
the photo cell wouldn’t get a stable reading. So if such an
oscillator were used alone, without the rubidium and
without an extra synthesizer to get to 10MHz, jitter
would be superb. That’s not the case and the output
spectrum is rarely clean. It’s only centered at a very precise
frequency, that’s all. That’s their only purpose.”
我们都知道10m是50欧BNC,独立时钟是75欧BNC,两者参数要求就已经不同
我曾经从别人那将一台10m锁定一台低端的带10m接口的时钟
声音最后出来,居然跟我自己在用的Grimm CC1独立时钟不分上下!!!
后来接了台更好的10m接口时钟之后,才能还原10m原子钟的真正本色
以及10m的时钟得买2000-3000元/米以上的时钟线才能出真正的声音,真的不是玄学
时钟的准确度(皮秒、飞秒级)和稳定性(相噪等)是两个非常不同的东西,后者我个人认为比前者更重要
就像你说的,如果中间多一台AES设备,那么时钟的稳定性会大幅度下降,会影响声音的空间成像、密度、清晰度
