The MA7000 and the MC252 both have autoformers in their output stage. Both are rated @ 250W/channel. The amplifier section of the 7000 has several improvements over the 252, including improved layout and more power supply capacitance. My system includes the 7000 and I feel it exceeds the 252,levinson 383,and Sim Audio I7. I have owned or listened to these pieces extensively before purchasing the 7000. The 7000 has an extended top end that is detailed, very smooth and easy to listen too. Soundstage and power reserve were also better than the others. The five band EQ is a great addition and does not degrade sound quality and can be bypassed.
