the Ayre unit could very well be just a minor step up from the Oppo (as Mitch2 describes)
Cmalak, to clarify, "just a minor step up" is not at all what I was implying and not what I said. My intent was to point out that several well known modders are reportedly achieving "significant" improvements to the stock 83se, and that the Ayre (which I believe is based on the 83, not 83se) is likely at the "top of the heap," with even greater improvements compared to the other modified units. Charlie Hansen and his crew have reportedly added improvements to the DX-5 that place it's sonic performance at or above the level of the C-5xe MP. I wish I could afford one.
