Bought one maybe 3 years ago and have not been tempted to replace it or had to mess with it beyond the occasional bias adjustment. If you want a definite tube sound you will not like it, it happens to coincide with my definition of what neutral sounds like so I do like it. Have paired it with Vandersteen 5a's and previously dynaudio confidence 3's, either match seemed to work well, the C3's were 4 ohm 85dbw and the Zeus replaced 300wpc solid state driving them. Am driving it with Rogue's Magnum 99 pre configured for balanced output and one balanced in and slightly hot rodded at the factory, there seems to be some nice synergy there and the M99's are selling used for good value if that is of interest. Last tidbit is there is some improvement to be had from calling Rogue and having them send you NOS 12ax7's and 12au7's. All just imho. Good luck with whatever you purchase. Oh, very last tidbit, if you don't need as much power, others have reported better synergy with their systems with 120's or 150's.
