pautinqch,
About the Eastern Electric DAC, the review by Stereomojo is very good. You have a link in the first page of this thread.
Another good review here
For the link i gave you on ebay, a lot of countries are excluded. Where do you live ?
About the Audio GD NFB1, I have no information, but a good PSU is always a good thing.
The Audio GD is balanced, you have XLR output. The Eastern Electric is only single ended.
