Dont be put off by Gary's Mundorf fetish. Lol. The Max copper is a good cap, and about 2/3 the price of the SGO'. I had the SO's in my system and not the SOG's although I think there is a pretty strong family resemblance. The So's are basically unlistenable straight out of the box, which is probably why I didnt like them. From reading they require 300+ hrs to break in so I am going to go back and revisit them. I may change my mind about them, but I have no issues with the coppers and they dont require extensive break in.
