Hello, I'm driving my Audio Technica ATH-A500, which have an impedance of 64 ohms, with my early 70s Marantz 2220B receiver; lately, I've been noticing a crackling sound whenever any bassy material is played. Makes things quite unlistenable, so I've been using a discman recently instead, which does a fine job of driving the phones. My question is this: is there simply too much power coming from the Marantz for these phones, or does the Marantz unit itself have a problem? Or any other suggestions. Any responses are appreciated, thanks.
