Is there a"giant Killer" CDP ?

Im looking for a high end CDP (one box or two box) to be absolutly great on reedbook. There are the renown ML 390S,Wadia 861, Capitole,Accupase 75V etc. I wonder if anyone actually has use one of these or any other true high end players in their own system and tried a cheaper solution and found it better than the true High end player.Please comment only if you actually tried both players in your own system!
I dont think you can judge who is better comparing players in shows and in stores!
