I too own Ayre C5xe and have a valhalla power cord on it. Stunning, and far more musical than sony. Sound stage is an affect that too many people try to get to with gear in audiophileism. Music is what's most important! If the speakers are set up properly in the room then the sound stage will fall in to proper place accordingly. If the speakers are set up right for the room and the coherency, timing, rhythem, timbre, etc., all couples well to that room and the soundstage still lacks, well it's time to upgrade! C5xe is better and it's a much better design internally. Valhalla power is like adding butter to toast. You have to have it.
