LMAO!! Sorry Davve! The pic above is a needle nose plier. A chip puller would be best, but most folks don't have one. If your fingers are small enough, you could do it that way. Mine are just too big.

As earlier indicated by an user the diodes are way to strong for my taste,, (also some are bright green while one other are more blue-greenish)

The volume knob was also broken (only the plastic thingy the potentiometer works fine.)

but I'm happy..
The flashing coaxial light means something. Email Lawrence and ask him, and tell him about the volume knob, to see if he'll send you one. I have replaced mine with better knobs from Parts ConneXion because I don't like the guitar style knobs.

Thats great! I suppose you could pause and pull some nose hairs with it, but maybe you'd get all of them in one pull!!
I'm glad it's all working out.

They didn't include the LT1364 for the dac so I am stuck with just the 2 LT1469CN8#PBF in the headphone amp at the minute. I used needle nose pliers to remove the old op amps as it was fiddly to get my fingers in their. I'm going to wait a week to see if they forward the LT1364 on separately before I buy one but so far so good.

I've got about 12hours use on the Zero now, i think it's sounding better now although this may all be in my head as I can't specifically pick out the differences not being a audiophile. Drums seem clearer, bass is getting deeper and songs with acoustic guitars you can hear the strings being strummed quite clearly.
Yeah, I also got 2 1469's but did not get my 2 1364 nor my 2 1361's. Do you think they are out or just sending everything separate? I got the 1469's on Monday (1/28) but nothing since. I ordered all samples at the same time.

I want to get all before I open it up and do my testing!!

Zero LED Mod

It's time to remove the sunglasses ... my Zero LED Mod:

1) Unscrew the LED circuit board.
2) Remove the following 3 resistors and solder 4.7kOhm 1% resistors into the empty places.
3) Test the brightness in relation to the green LED. If it is still too bright, try 10kOhm or more.



4) Reinstall the LED circuit board.

They look much better! Would you say the brightness was cut in half?
Thanks!

I assume more than half... I reduced the current from 18mA to 1mA.

I'm going to look around and see what I have. I sure would like them to be far less bright.

Something bad happened to my OPA627's. Left channel went gone and I hear popping noises from it. When I removed the op-amps they were pretty hot.

I have now listened various music with DY2000 metal in the DAC and I like the sound so far. Nicely detailed and smooth. I will try later those OPA627's again if they were just overheated and sounded bad.

Mine seems to have developed a pop or a crackle that seems to happen periodically. I was listening to vinyl for a while so I didn't really notice it that much, but when listening to CD's its right there. I'm pretty concerned but I'm ganna let it rest for a while before I get to frustrated.
