Sony SACD 555ES or Arcam CD-92 for redbook

I have a few hundred redbook CDs (no SACD yet) and can get both of these for around the same price. Which one would be better for straight redbook use, thanks.
Neither.'s bedtime, and my skepticism of multi-players prevails again!

The Arcam CD-92 is not a multi-player, could you be a little more specific in your response. Thanks.
