I have been looking into purchasing a new receiver. My choice is between the Marantz 5300/7300 and the Harman Kardon AVR525. The Harman Kardon specifies the peak current handling capability as 45 Amps. There is no similar current number specified for the Marantz. I was wondering if anybody knows about the peak current capability of the Marantz 5300 or the 7300. Any input is appreciated.
