I received my Supermicro last week, and I really like it.\r\nMy source is a Sony R50 and I'm using ER-4S's for cans.\r\nAs expected, the bass is more impactful and sits more evenly in the mix. Instrument seperation is better as well. I am really surprised at the increased levels of detail retrieval. It's really amazing. The amp is really quiet as well; the background is completely black at all safe listening levels.\r\n\r\nAnyone else loving this amp? I doubt I've burned mine in yet, so I'll keep updating this thread as things progress.\r\n\r\nI also ordered the mini to mini plug from Xin. It functions perfectly, but looks really cheaply made. The tape used to wrap the 90 degree plug wasn't put on evenly and it looks like it could come off quite easily. Oh well.
