I have a D-Sonic 1000S (in use since last August) and am extremely pleased with it. It runs cool, sounds great, gives lots of power, is physically small, quite efficient, and priced affordably. I too studied the various icepower offerings from other manufacturers before going with D-Sonic. As far as I can tell, the performance of a 1000ASP module is pretty much equivalent no matter who sells it. The only real difference is in the looks of the case of the amp. Jeff Rowlands look much nicer, but it was an easy decision to go with D-Sonic after comparing prices. I wouldn't call the D-Sonic cases stunning but they're unoffensive and not as ugly as the Wyred4Sound ones.
