:?: I dunno. My model is a Sony MDS-JE520, if that's any use to anyone.
My portable DOES clip, though (making that nasty scratchy sound).
But with the deck, it's not like I'm frying the circuits or anything; just pushing the level against the 0dB limit, so it occasionally pops into the red. But then when I do fry the circuits it distorts just like tape, ie. no digital clipping.
