Default New Here, Please Help

I am new here, but I have been reading about this DAC, so can someone please help me on how to go about in purchasing the kit? So far this is what I know, that there is a group buy, but not sure how to put myself in it, and how to go about in paying. Essentially, I am not very familiar in joining a group buy, I mean, on how to join in.

I am very much interested in this kit, please help me on how to purchase the kit.

Alex

Sorry, but it would not let me. When I click on the spreadseet, it opens up, but it would not let me put anything in it? How do I put my name in it. Sorry for the ignorance.

This was for the group buy number 1 so Quanghao will open a new one for this new group buy.

Hi audiodesign,
how do you compare this new discrete differential no feedback output stage with the LL1684 that you previously recommended as one of the best option?
Could the last firmware be considered final or there's still the necessity to buy a PICkit 2 programmer?

I have a couple of LL1690, I read the older thread but I couldn't find anyone who has tested those transformers with this dac. Do you think they could work in this project? I would like to save some money initially and upgrade to LL1684 in the future
