Linn Katans; apart from being dynamic and extremely accurate from the outset, they offer what few other monitors do... scalability. Katans make a quantum leap when they go from passive to active configuration... you can start with a passive system and slowly add... first a sub to fill in the base and eventually active amps. I started out several years ago with Katans and rotel amps. Over the years things have come and gone (eventually settling on an all Linn system), but the one thing constant has been the monitors.
