The Ref 5se uses a 20 amp power cord. There are pictures of the back on the arcdb website.
I have not heard either of the Anaconda power cords. I have heard that the later version was not quite as good as the earlier but I don't know. Like most companys, some of their pieces are real home runs while others are not quite as good. The HC versions have better shielding and usually sound better than the regular versions.
folkfreak, Does the Ref CD9 use a 20 amp power cord? I know that my Ref CD7 uses a 15 amp and I believe the CD8 does also.
