DIR9001 XTI must be connected to DGND

Since there was no response to my previous post, I had the DAC opened up and soldered a small piece jumper wire to connect the DIR9001 XTI input pin 8 to the DGND (as per DIR9001 datasheet, when it is not using external clock source)

After this fix, the sound from the CD - SPDIF source became much for solid and dynamic. It is quite similar to the character with the USB source. I was very surprised with this change.

I can't say this is a design fraud but I firmly believe this should be the right kind of sound it should be. I hope someone could try it and see whether they like this change.

Comments are very welcome.

我是从香港杂志得知这台mini USB DAC,一直都不满意由计算机放出来的音乐,(本人以前也烧过一阵子,现用Cary前后级推黑檀Roger LS35A 比较喜胆味)终于订购了DIY Kit 自己焊来玩玩,基来也没有太大难度,开声后run 半天后试 ...

图片上的帖片运放是什么？DIP-8的声音不好吗？

PCM2706，加BB1700系列太低端了，音质很差。初级发烧，学生可以要、
