Great to see this thread!
I bought the LD6 together with juzmister, and got bit to say about the noise. I got the LD last night and as soon as I switch it on, there is a very loud and unpleasant noise, which was loud enough to distrupt me enjoying the music.
A little further examination tells me that it seems LD is using a REALLY crappy fan.
So as soon as I got the LD6, I decided to replace the fan, which is essentially 2 80mm 12VDC pc case fan. The only problem here is the fan supply voltage is 24V (not exactly, I got 21v) instead of 12V. Which means the 2 fans have to be modded in they way that they work in series. This config is a bad idea because fans even from the same manufacturer have different internal resistance. This will end up with an unbalanced voltage distribution. The result is one is faster than the other.
Anyway, I replaced the fan with ANTEC TriCool, and the result is very delightful.
Although I am complaining here, I think this is just a very slight design problem that has no way affect the overall build quality of the LD6, it sounds very sweet and refined. The bass is tight and strong with detailed mid/high. I have raised the issue to the designer Mr. Yang, but not sure when he will get back to me.
Just some photos here...
