The C5x-e is Ayre's first SACD/DVD-A player which is somewhat of a suprise given some comments made by Charles Hansen in the past (although notice it is 2ch only). But the addition of SACD and DVD-A didn't come at much extra cost. The comparison above is Redbook only and is quite a statement for someone to make given the performance of the CX-7 and D1-x at their price points. I haven't heard it yet but I plan to in the next month or two when I do my audio upgrade. I mainly care about Redbook performance.
