Recommendation - Line Magnetic, Music Reference, Shindo, Lamm, Manley, and VTL (except I have seen excessive tube wear with VTL designs)
I totally disagree about Rogue (transformers buzz and ground loop issues) I had problems with CJ (6months to get a tube preamp fixed after they sent me the wrong tubes for a Premier 14 and cooked it) and ARC (use to have great service but now that they were sold off meh). VAC and Cary are crap where the designers blame the tubes and way too many trips back to the factory to make it sound nice. Cary has rolling changes on hardware which they aren't even tracking.
