Quote: I received my balanced headphone cables of HD800 and LCD-2 today. Yes, the 4-PIN XLR output is deadly quiet. I think we are close to address the problem. I found a weird black wire connect to ground pin of SE and balanced pre amp out. I don' t know where it comes from. I will ask...

 

 

Spent 2 hours to change the hardwire of my K1000. Pictures say everything.

  Quote: Sorry, I am too busy today to type more details about it. This picture came from a present user (maybe the only one) of this new upgraded MK VIII. All components are top of the top class, either quality or price. Even one of those capacitances in this picture costs hundreds...

  See here: http://www.head-fi.org/forum/thread/522099/little-dot-mk-vi-little-dot-mk-viii-se-owners-unite/75 But it does not fit those hungry headphone like K1000 and HE6.

According to Woo's diagram, I think WA22 amplify balanced signal by full balanced circuit, and then transfer amplificatory balanced signal to single end output to headphone. The purpose of balanced circuit is to reduce noise I think, so this design seems to take the benefit of balanced signal...

I guess this buzz problem dues to the ground wire of SE and 3 pin XLR output. 4 pin XLR output may not be affected because it does not have ground pin. I am waiting for my 4 pin XLR headphone cable to verify that.

In chinese forum of LD. This amp won a competition of headphone amp last month in Hongkong. I just asked Mr. Yang when it will be available. He said LD will start to accept order after new year holiday. Price is varied, depends on what components you choose. Here are some pic of this amp on that...

In fact, VIII is designed for high impedance headphone. It does not work well with low impedance cans as VI. Actually,  Mr. Yang  made VI for K1000 and VIII for HD800. He ordered some custom components  from EU for VIII. Those components are really more expensive than regular model. So VIII...

Someone AB compared WA22 and LD MK VI+. He found MK VI+ had better sound. I doubted this conclusion ever because it was hard to believe a $700 amp could beat a $2000 one.   When I see inside of WA22 here, I think I understand why and that should be ture.......

Mine was set on low gain upon receive. Not sure others.

Quote: Thanks. But it is really not a problem to me. Because I bought this amp just for my K1000. I can not hear any noise with K1000. It is a bonus to drive LCD-2 so good. I never try DAC from LD. I heard their new top DAC (DAC3) was coming soon. Actually price is influenced by...

No, I don't have any battery based power. And I think it is still a ground problem. I opened the amp and try to find how the ground wire connect. But it looked too complex to trace. I must mention that the SE output of MK VI+ is just an adaptor of the balance output. It is drew from R+, L+ and L...
