Top three most over underrated eqpmt??

Throughout my 17 and some odd years of being into this hobby, I've had numerous equipment with some being so so, some being great, and the rest being bad....Just curious to find out what other people's experiences are with changing from one component to another...Well, for me here are the list for my top 3 most overrated equipment: SimAudio W4070 amplifier, Aragon 47K preamplifier, a tie with Kimber PBJ interconnects and Linn Majik integrated amplifier....my top 3 most underrated equipment: Chiro C-200 amplifier, Roksan Caspian integrated amplifier, Straight Wire Chorus interconnects....comments anyone???
