i have the fpb600c and have since new around 2003. it has always functioned perfectly and really sounds better now than ever. rayoo's description is pretty dead on. fast, clear, powerful, dynamic and did i mention the bass? you will never want for more bass impact...ever. kick drums feel like body blows. i like em. i will say equipment matching is important with krell as cables are. i sort of tame mine with cable choice.
i do not find the heat to be excessive but they will significantly raise your power bill. seriously.
it should be mentioned that they are very large and very heavy. the build is outstanding all be it somewhat over built. i store canned food in mine in case of nuclear attack, i plan to pop off the top and drag me an my dog in for shelter. i do feel bad for my wife but really not enough room...
