oops i made an error in my post regarding the oppo 83se as an sacd player.
i heard an onkyo sacd player costing under $400 and when i brought my oppo to my friend's system, i ended up preferring the onkyo.
i assume that i would prefer the sony, but there have been other threads about this player and there have been differences of opinion as to its sound quality.
i am waiting to try to pick one up at a very good price.
there is also a modwright tube output stage that has been used to improve its sound.
