Great as usual, especially the last part- change channels

So are there any reviews in the works for the hypex modules? Maybe the CIAudio D200s(I have heard these) or the DIY Cable version. I have been thinking about building a 2ch amp with UcD400 modules for some DIY S+Gs

Over at audiocircle there has been LOTS of talk regarding this article.
This is just one thread.

Some interesting stuff. I guess the head designer(TNT) at Nuforce was posting incognito but was revealed by accident. He was knocking the article and Hypex modules while trying to redirect the thread. Also it was mentioned that some of those nasty scope photos were infact the Nuforce refrence 9. The head designer did not dispute these accusations which leads me to believe them to be true. Not that I think many people here are shopping for 2ch monoblocks in that price range but I thought it was interesting none the less.
