一直想将QB9升级成DSD,这几天联系了香港极品音响,获知:费用4500,寄到广州即可;如果自己带到香港,还会更便宜;升级不只是将芯片从1796换成ES9016S那么简单,除了牛之外,几乎所有的内部零件都要更换;不过,由于工厂产能的原因,所有零部件要提前三个月预定,比较漫长;前面板不会换,那个DSD的标也是贴上去的,这点吐槽一下!
我查了国外论坛一些资料,主要变动大致如下:
- Changing the DAC chip from the Burr-Brown DSD1796 to the ES9016S.(DAC芯片从BB的1796换成ES9016S)
- Replacing the audio master clocks with low-phase-noise modules running at twice the frequency of the previous ones, which allow the ESS DAC chip to perform at a higher level.(主时钟换了,频率是原来的两倍,杂讯更低)
- Changes to the analog audio circuitry and its power supply that improve the audio performance.(模拟输出线路及电源供应也有变化,以提高声音表现)
- Addition of an AC line powered supply for the USB circuitry. This provides for uniformly superior performance, regardless of the quality of the USB Vbus power supplied by the computer.(AC电源直供USB线路,无视电脑USB口供电的影响)
- The ability of the USB Audio input to accept and decode native DSD files from computer sources.(USB输入直解原生DSD音频文件——9016s芯片的功能,原来的9018是不能直解的)
换言之,升级成DSD后的qb9将是一台全新的机器,而且据说声音比老板192的更好,貌似国外论坛的反应还是比较正面的。这里赞一下ayre,这种可升级的模式还是比较贴心节源的,不像某些厂家,三天两头出新型号。仅供烧友参考,我是毫不犹豫升级了。
