Hi Colin,
why don't you try with an Oppo that costs about 160 pounds and you can play Sacd, Cd, Dvd-audio. For someone in a blind test it sounded better then a Wadia that costs much more! Anyway, I didn't test still this player but reading on various magazines it's a sort of buy hint.
The mechanics isn't good at all referred to other expensive players but oversampling the bitrate cd's would sound better ...
